Entered Sierra book max loads using both 7828 and Re-22 for 160 GameKing and getting low pressures (high 30k's/low 40k's) and velocities (2600's).
Case capacity seems correct (74 gr H2O) as is bullet length. COAL is per manual 3.325".
I adjusted weighting factor from default of .5 down to .4 (i.e., more overbore).
Anyone seen this before? Can't figure out if I'm doing something wrong and why there is such a big variance from manual and Alliant/Hodgdon websites.
PS Yes, I know QL is an approximation, but it's usually not off this far, esp. for a SAAMI cartridge.
