Chronographed my AR loads for my Brazilian 1917, 454190 and some AA#5. Surprisingly I got a one hole group @ 10yds casually shooting over my truck window sill to make sure I don't shoot my chrony. I sized the bullets to the throats (.454+) and want to group at 20 to25 yds. The 250gr. Bullets averaged 820fps and 373fp. Don't know what it would be good for, however I have a few loads with 250 gr cast hp in a soft alloy that seats deeper in the case and was wondering if any adventurous types would like to touch off a few?
