So first off I apologize that my question is not about cast bullets. But I think it is applicable here. I am working up a 300 grain hornady hp load for my 45 70. The best group is only shooting about 1600 fps.
(4shots at 1.35 in.) I emaimed Hornady and they reccommended a minimum impact velocity of 1600. That got me wondering. I am already starting with a 45 caliber bullet and even if it didn't expand, wouldn't that hollowpoint act like a wide meplat and still do considerable damage? The rifle is a 1895 SBL and only has a 18 inch barrel so velocity is hard to attain without a lot of pressure. I had shot a group that had a velocity of 1700 but had a 3.9 inch group at 100 yards.
