1.                         IMPORTANT ADVICE
*************************************************************************
Because QuickLOAD is not intended to be a substitute for Reloading Manuals, 
instructions covering good (safe) reloading practices are not included here
or anywhere in the program's manual ! 

   Therefore, working with QuickLOAD's data assumes professional ballistics
   experience or at least expert handloading skills. It is mandatory to use
   a good reloading handbook, for example, such as the Dynamit Nobel book 
   'Wiederladen', the DEVA Manual 'Wiederladen', the A-Square Manual,
   the Barnes Reloading Manual, the SNPE Handloading Manual, 
   the Vihtavuori Reloading Manual, the Lyman Reloading Manual, the DPI
   Metallic Cartridge Reloading, the Nosler Reloading Manual, the Speer
   Reloading Manual, the Hornady Handbook of Cartridge Reloading, the 
   Sierra Reloading Manuals, the Hodgdon Manual, the Accurate Loading
   Guide, the Lapua Reloading Manual or any other recognized manual that 
   may offer all of the appropriate information.

2. Changes/Corrections
****************************************************************************

12-August 2005

   Vihtavuori N 150 powder data adjusted - now faster. Old data too
   slow and measured pressure up to 20% higher than calculated ! 

Version QL 3.1 containing pictures and/or cartridge drawings of over 400 cartridges
Version QT 3.2 has interface to MEHL BMC18/21 and PVM 21 chronograph.
Version QL/QT 3.3 contains some canges due to Vista.

5-December-05

Since Version QT 3.2.0.9 there is an AirgunPellet.bul file for QuickTarget
included. I holds about 100 airgun pellets with their BCs. QuickTarget
calculates now within a velocity range from 5900 fps down to 30 fps.

1-January-07
Version QuickTARGET Unlimited added. ß-Version 0.1.0.0
At this time only 3-DOF, extension to 4-DOF is planned, so far
a feasible model estimating missing coefficients is found. 
All bullets of QuickTARGET/QuickLOAD can be used in QuickTARGET Unlimited
in conjunction with selected G1-drag function. Old QuickTARGET will stay
because it is more easy to use and sufficient for hunting purposes, the 
'unlimited' version addresses long-range shooters.

8-February-07
Changes to Setup and Quickload and Quicktarget programs applied due to 
severe annoyances in Windows Vista(Build 6000). Now QL/QT works with 
Vista. Sorry for all who must use Vista, a 'pig with a lipstick'. 
QuickLOAD V.3.3.0.0, QuickTARGET V.3.3.0.0,
QuickTARGET Unlimited added (Point-Mass Ballistic,english) V.0.1.2.0
  To get rid of the annoying Vista-UAC-inquiry when starting a program
  use Regedit to change 
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
   Key: ConsentPromptBehaviorAdmin = DWORD:00000000
 If you have Vista Home pre-installed on your PC (Recovery version) the program
 may refuse to show any window on your PC. In this case 1) Click START
 2) Type: cmd 3) Right click cmd, click Run As Administrator
 4) Type: net user administrator /active:yes 5) Press enter
 Now log off, log on with the new administrator account. Install QL.
 QL should now run properly. After restart under different account it 
 should run too.

24-Mar-07 
Error in Quicktarget Unlimited: Calculating target position from GPS
gunsite position: Compass angle entry for older versions must be 360 minus 
compass reading. Now in V.0.1.0.5 resolved.

3. Remarks to the accurate adaptation of propellant data
*****************************************************************************
   
   ADVICE:
   Complete instructions covering good (safe) handloading practices are not
   included here or in the program manual. Therefore, working data must be
   supplemented by a good modern handloading handbook such as Dynamit Nobel
   book 'Wiederladen', DEVA Manual 'Wiederladen', A-Square Manual, VihtaVuori
   Reloading Manual, Lyman Reloading Manual, DBI Metallic Cartridge Reloading
   (3rd Edition), Nosler Reloading Manual, Speer Reloading Manual (12th or
   13th Edition), Hornady Handbook of Cartridge Reloading, Sierra Reloading
   Manual, Hodgdon Manual, Accurate Loading Guide, Lapua Reloading Manual
   or any other recognized manual that offers the appropriate information.
   *****************************************************************************
   
   For sake of computational speed, and to avoid possible non-resolution
   conditions (which result in faulty output or infinite computational loops),
   some calculations used in QuickLOAD and QuickTARGET use simplified formulas.
   This necessity sometimes causes unsatisfactory results. For example:
   QuickLOAD represented the duration and degree of work acting on the
   projectile (in any manner) against chamber pressure only by a simple offset
   pressure. We could optimize this function by implementing a more realistic
   resistance function. However, who will supply the inputs that approach would
   require? Even recognized internal ballistics experts disagree about the
   appropriate values. Therefore, sometimes, cartridge-specific adaptation work
   is required. An obvious example is in normal pressure rifle cartridges that
   are cylindrical or nearly cylindrical, where QuickLOAD cannot account for
   slower effective granule ignition in the front part of the charge, which
   results from the lack of turbulent mixing of granules that is seen in
   bottleneck cartridges when the powder funnels from the case while following
   the bullet. (See discussion below.)
   
   Please proceed carefully while making changes. Pay close attention while
   comparing results with published loading data and chronograph results.
   Published values are often rounded and occasional misprints exist. (The
   latter have formerly been quite common). Owing to safety concerns, in
   respect to the expected and recognized nominal lot-to-lot bandwidth of
   burning characteristics, published peak chamber pressure values are sometimes
   higher than actual laboratory derived values.
   
   It is also true that within some handloading manuals, separate tables for
   European CIP and American SAAMI limits are listed, e.g. VihtaVuori #s 1 & 2.
   However, CIP and SAAMI test methods are not identical. Therefore, no exact
   correlation between these (or any other) accepted pressure measurement
   methods either exists or can exist.
   
   Owing to this problem, we have a curious result. Sometimes, for the same
   cartridge and load configuration, the minimum charge shown in one table
   exceeds the maximum charge shown in another table. Obviously, this is
   erroneous.
   
   Absence of statements indicating the specific method of chamber pressure
   measurement (copper crusher, Piezo, etc.) renders any stated pressure value
   essentially unusable for any adaptation or modification of propellant
   properties. QuickLOAD calculations are calibrated only for corresponding
   piezo pressure values. These readings are approximately 1.1 to 1.3 times
   greater for rifles than values generated with the CUP method for rifle 
   cartridges (copper Units of Pressure - copper crusher). 
   For pistol cartridges it is just the opposite. However, outside side by side 
   comparisons, there is no method of direct pressure data conversion.
   Any such attempt is certain to lead to significant error - do not attempt it!
   
   ----------------------------------------------------------------------------
   You should know that there exist a legislative so that your handloads must
   stay below maximum pressures when you live in countries which ratified the
   CIP decisions. Using ammunition exceeding maximum pressure is illegal in those
   countries !    

   Only measurements with standardized equipment providing exact data of both
   muzzle velocity and piezo pressure can give a valid comparison. Further,
   that comparison is only valid for the specific combination tested.

   Pressure and velocity testing services are available to the individual
   handloader. Available test barrels you will find in file testbarrels.htm on CD.
 
    Such measurements are done e.g. in Germany for handloaders by:

    DEVA-Institute, Dune 3, D-33184 Altenbeken, Phone +49 5255 7343, Fax+49 5255 7305

   -----------------------------------------------------------------------------
   
   Powder burning rate anomalies related to case design, size and insufficient
   ignition:
   This anomaly has only proven to produce QuickLOAD calculations indicating 
   higher than actual pressure and velocity. 
   
   In certain small-caliber cartridges, those types with relatively small
   combustion chambers and in some big-bore cartridges, those types with almost
   cylindrical cases (which often require the same types of propellant),
   QuickLOAD often significantly deviates from suggested published reloading
   data.
   
   For such cartridges, it can be meaningful to adapt an existing propellant
   data file. The resulting powder data file is applicable only to the
   specifically verified cartridges. Store this data record with a special name.
   
   (Candidate cartridges include the following and similar chamberings:
   45-70 Government, .458 Win Mag, .22 Hornet, .30 Carbine, .416 Rem Mag, and
   all the old Nitro Express cartridges.) For example, propellants in the
   .458 Win Mag, .416 Rem Mag and .22 Hornet demonstrate a somewhat better
   efficiency than QuickLOAD's standard calculation suggests. This results in
   QuickLOAD predicting increased pressure and velocity, when compared to
   published data or chronograph results.
   
   To correct predictions is possible to enter a somewhat bigger cartridge case
   volume, compared to what actually exists. This causes a corrective effect. 
   For example, in the .416 Rem Mag, misrepresenting case capacity about
   +7% often results in good correspondence with published loading data.
   
   This method limits the effects of input data alteration to the specific
   cartridge, which seems better than creating an imaginary powder data file
   that will only be useful and appropriate with a specific cartridge or
   possibly a small class of cartridges. 
   
   The only problem with this approach is that it prevents direct assessment of
   powder loading ratio. That can be secondarily derived by temporarily
   reverting to the actual case capacity.
      
   Lot-to-lot dependent adaptations:
   When the user notes differences between the properties of a reference powder
   lot (which is stored in the program file) and a new propellant lot, an
   adaptation of the propellant data is necessary. Such differences will occur
   with practically each new powder lot. Sometimes these differences can be
   significant. For example: with many manufacturers, when the nominal Heat of
   Explosion is 4000 J/g, accepted lot-to-lot variation is between 3900 to 4100
   J/g.
   
   So long as no new values for the Heat of explosion are admitted by the
   manufacturer the old Qex values are retained and only the Ratio of specific
   Heats cp/cv and linear burning rate Ba are changed, as necessary.
   
   When calculated velocity (and pressure) are too high, the value for cp/cv is
   reduced. cp/cv-1 is approximately 0.25 and corresponds to the 'efficiency' of
   the transformation of the Heat of Explosion into propellant gases, which
   produce chamber pressure. (A propellant with cp/cv = 1 generates no gases,
   cp/cv = 2 signifies, that 100% of the available energy is converted into
   pressure.) Carefully change this value in 0.001-steps to correctly accomplish
   this adaptation. Increasing cp/cv increases both velocity and pressure
   (and vice versa).
   
   To adapt pressure together with this (lowering cp/cv), change the burning
   rate coefficient Ba. An increase of Ba increases pressure, a decrease reduces
   pressure. With this adjustment, velocity also changes. Change cp/cv and Ba
   until sufficient approximation to test result is achieved.
   
   When completely new propellant properties are available, the user can also
   change other properties.
   
   
   ********************************** WARNING **********************************
   
   For each cartridge and load, definite types of propellants are preferred.
   Other propellants are simply inappropriate.
   
   Since QuickLOAD allows theoretical experimentation with each propellant and
   cartridge, is it possible to model curious (and dangerous) loads.
   
   The transformation (burning) of most propellants (even porous types) at low
   loading densities and low pressures proceeds incompletely and atypically.
   
   In addition, many powders can ignite insufficiently, which can lead to high,
   potentially dangerous, pressures. This results from the chemical composition
   of the deterrent coating, which acts on the propellant. It also depends upon
   the geometric shape of the combustion chamber, bore design, bullet forcing 
   resistance and the nature of propellant composition. Often, only the
   propellant manufacturer knows the latter. 

   Always read warnings in actual manuals about absolutely minimum loads for
   critical powders like spherical powders or very slow extruded powders, for 
   example, H110, W296, MRP2, VV170 and VV500 series. Also avoid Load Ratio or
   case filling below 90% for very slow burning rifle powders, especially for 
   those "Super Magnums" like 7mm STW, .30-378 Weath, Remington Ultra Mags and 
   similar cartridges combining high case capacity with relative small calibers.
     
   Sometimes a tightly press-fitted or crimped bullet that results in significant
   bullet pullout resistance, is necessary for proper ignition.
   Otherwise, it is possible that after ignition begins a significant pressure
   drop can occur. This pressure drop can result from early bullet movement 
   (primer blast or initial combustion pressure that results from the burning
   of a small percentage of the powder granules) or from significant gas leakage
   past the bullet, i.e. seroiusly throat erosion, cylinder gap in revolvers 
   (which will occur before chamber pressure becomes sufficient to obturate 
   the bullet into the bore).
   Should this pressure drop be of sufficient magnitude, the nascent propellant
   gases can cool sufficiently to condense onto the unignited (relatively cold)
   propellant granules and heat them up. If the combustion process continues, this
   can result in unpredictable burning characteristics of the originally
   unignited granules. In addition, it is possible that some powder granules
   that are accelerated towards the bullet base by the primer blast will crush
   into small fragments. This happens especially at low loading densities and low
   temperatures. This will dramatically increase initial surface area.
   This would cause the burning rate to increase dramatically. Either effect
   could trigger the so-called 'Detonation' or 'Secondary Explosion Effect'.

   Charges, where pressure curves are predominantly under 15000 psi or 1000 bars, 
   do not correspond well with QuickLOAD interior ballistic computations. This
   is because at pressures under 1000 bars, smokeless powder combustion rate is
   not linear but is strongly exponentially progressive (as a function of
   pressure). The current version of QuickLOAD cannot properly handle this
   exponential dependence. Owing to this restriction, calculated velocity and
   pressure will often be higher than is actually produced by the resulting load.
   As with the above noted cylindrical and small case problem, this error has
   not been noted to result in any unsafe QuickLOAD calculation.
   
   Example cartridges: .45-70 Government, 9.3x72R, old Nitro Express, original
   blackpowder designs, etc.
