I used Laser-cast from the Oregon Trial Bullet company...http://laser-cast.com/.
170 grain sized .310, no gas check. Tried Unique at 8,9,10 grains, then spent about 3/4 of an hour cleaning the lead out of the bore. Total 30 rounds fired.
All at 50 yards: 8 grains loads were very random, lots of horizontal and vertical dispersion, no real group to evaluate; 9 grains had a semblance of a group, about 4" at best; 10 grains had 3 bullets hit the 8x11 paper at 50 yards and I think this is what caused the barrel leading. Company claims they won't lead the bore of your money back.
I started with a squeaky clean bore.
I've been reading everything I could find on loading lead but obviously I'm missing something to get such poor results.
Next outing I'll be starting at 7 grains and going up to 8.5 max by 1/2 grain steps.
HELP!!!!!!!!!!!!!!!
PLEASE!!!!!!!!!!!!!!!!!!!!!!!
