*Max Load:
For your own safety, never start your load with the maximum load, always start lower and work up to it, whilst checking for pressure signs at all times.
*Start Load:
The start load is derived using standard Quick Load input values which were NOT calibrated for any given rifle. The start load = Maximum pressure minus 25%. This load is deemed safe for the first rounds fired in your rifle. The load can be worked up gradually to safe maximum pressures from this point.
*Start Velocity:
The start velocity is calculated from the start load. This velocity may not correspond with your measured velocity due to powder lot to lot differences, case volume, primers used, rifle barrel dimensional and surface condition variations etc.
*Case Fill %:
The case fill percentage in principle show that the slowest burning rate powder yielding the maximum case fill was selected. Under maximum load conditions the case should be filled close to 100%. If the case capacity exceeds 100% during your Quick Load calculation then be on the look out for “compressed” loads. If compressed loads are experienced then use the next slowest burn rate powder, if available. Please contact for assistance.
Use the recommended primer for your case. Better quality primers will result in better ignition and smaller extreme velocity spreads.
Omitted Calibres:
Please contact Balistix Bullets if you need assistance on calibres not listed above. (
Cartridge Overall Length. The COAL stated is this table is according to the SAAMI specification. The COAL is measured from the base of the case to the tip of the bullet. (Please refer to out “Reloading Tips” for proper measurement techniques)
If possible, we recommend that you determine the COAL of your rifle, and load your bullets at 1mm short of the lands.

Powder Selection:
The powders shown above by no means define them as the best powder for your load. It is a known fact that different burn rate powders may yield better performance in certain rifles. Please use whatever powder works best for you but always be safe and when in doubt contact or your propellant manufacturer.
