Few days ago I cast some 311041 for the Sneezer and since I have in recent months been enslaved with the finer details, I decided to weigh them. Actual count was 199, so I came up short of the intended 200. Oh well, I can be short to on occasion.
Not to say I haven't paid attention to other bullet weights in the pastime, but I've mostly done this with bigger bore stuff loaded with Lord Black. About 5 years back I had an online discussion about weight variation for my .45-70 bullets and found I had insulted one of the members of that fraternity. I had a 3% spread in weight for 530 gr bullets and he opined that sucked. Said that .3 grains was an acceptable spread. None of the other disciples argued with him so I figured that was the Holy Grail.
So, today I weighed the 311041 lot. 199 bullets with an extreme spread of 2.7 grains. Now I had identified 5 bullets with minor inclusions and marked them for use as fouler rounds. I wound up with one lot of 50 bullets with a .2 grain spread. Another lot of 58 with no spread and a third lot of 57 with a .2 grain spread. 165 bullets total. in that group. Extremes of the curve were a 1.8 grain spread for 21 bullets on the low end and .2 grain spread for 13 bullets on the high end.
Now it is with anticipation that await finding out if this will make and difference. Started working with a change in primers a short time back that reduced velocity spreads over 50% for 5 round lots of ammo. Added a small charge increase and bumped up the velocity as well. A few days ago I shot a one hole group with the 311041 bullets at 50 yards that had not been weighed. Bit earlier I had fired a couple of groups like that with the old working load.
Any of you fellas fiddle with this stuff and if so, what have you discovered?
Or and I the King of all Loonies?
