Howdy, y'all -
This is my first post on this forum - I was referred here for possible help with an accuracy problem I have with my .45-70 crack-barrel Henry.
First, by way of introduction, my "fer real" name is Sam. You can call me that or anything else except "too late to eat". My initials are SOB (really!), hence my handle. I'm bumping 70, USAF veteran, ain't got a wife, don't want one , got my guns to keep me warm. I like good beer, good eatin' and good companionship, I love to joke (especially at my own ugly self!) and I love to help my friends. Born and raised a north Louisiana country boy - I'll offer anyone my hand in friendship, but if they throw a punch they'll get one right back.
Anyway, enough carrying on about me. I have a bit of an accuracy problem in my Henry. It will shoot groups with jacketed bullets that are tighter than Ole MacGregor's coin purse, but cast boolits are all over Hell and half of Louisiana. I slugged the bore - groove diameter is .4565, bore probably a few thousandths less. The hard cast boolits I've been using mike at .458 and .459, so they should be fine. Granted, I've been pushing them at 1800 - 2000, which may be a bit much (BH is 16 or so), but I shot some with some Holy Black which should have given me ~1300-1400 and they still scattered like a flock of scared hens.
I'm perplexed, flummoxed and bumfuzzled over this. I posted a couple of pics of groups I shot at 25 yards (indoor range) for illustrative purposes. Any input y'all can provide will be muchly appreciated!
