Hello all, today I was working up a load for an upcoming moose hunt. I'm using a Mihec 375-275 purchased from a group buy about two years ago. With my lead the bullets weigh in at 273gr including gas check. I am using 34gr of H4198 and a dacron filler. The load has proven to be very accurate with no pressure signs. I forgot my chronograph so I don't have the speed but the book estimate is around 1900fps.
I noted that the shots were all 6" high at 50 yards but when I loaded my 270gr jacketed rounds they only shooting an inch high. I made sure to shoot the same each time and not let the barrel rest on anything.
I found it strange the lead would group so high, any ideas as to why?
