Thank you! The rifle is a first model Newton. The buck “plowed” forward for about 20 yards at the shot but both front shoulders were toast.
I usually use 270 win brass to form the cases. On some brands of brass it was necessary to ream the or turn the necks after necking them down. I’ve shot these 123gr bullets and 140gr partitions and both shoot pretty well. H4831 or IMR 4350 seems to work well.
