Well it was such a nice day high was 52 degres. I went to the range to find out how fast these 300 gr bullets would go
with max load of imr4350. They went 2648 fps thru my conagraph. I don't think that was to bad I mean after all it is a 375 H&H. There were no flatened primers everything was normal. So now this summer I'll find out how they fly to 200 yds.
I shot those at 100 yds and the group was less than 3/4"
5/8s" more like it.
