I am seeking advice on the best path to pursue for loading for a 45ACP glock 21 and secondarily 1911 style pistols.
The bullet I want to use is Rim Rock bullet's .451 250 gr. RNFP BHN 15, which as loaded by Buffalo bore is by far the most accurate bullet I have fired in a Glock 21.
Buffalo bore loads "+P" ammo, and I am not necessarily looking for a +P load; just one that will cycle reliably.
Load data for the 250gr lead bullets is scant, at least pressure-tested loads are, so I am extrapolating from published loads by Alliant for their 260gr jacketed bullet.
these loads are:
45 ACP, 260 gr JHP
Bullet Powder Weight Powder Velocity OAL Primer Source
JHP 8.3 gr Blue Dot 780 fps 1.21" Fed 150 Alliant
Pressure: 19,000 Suggested starting load: 7.5 gr
JHP 4.5 gr Bullseye 725 fps 1.21" Fed 150 Alliant
Pressure: 19,400 Suggested starting load: 4.1 gr
JHP 5.9 gr Herco 750 fps 1.21" Fed 150 Alliant
Pressure: 18,600 Suggested starting load: 5.3 gr
JHP 5.4 gr Unique 760 fps 1.21" Fed 150 Alliant
Pressure: 19,400 Suggested starting load: 4.9 gr
(hope those pasted in understandable format)
Anyway, should I be looking for velocity or pressure (all are 18-19K, but still) to reliably cycle the autoloaders?
Alternately, does anyone have any experience w a load, preferably pressure-tested, using the 250gr cast bullets; that worked well w the Glock 21 or 1911 platforms?
many thanks,
