Hey guys,
I've got a 22br I put together a few months ago. It's a .252 neck. I've done very little load development with it (busy with life lol). Ive loaded and shot a few rounds to break in the barrel and get close to zero.
I loaded up some 52gr mk, benchmark powder, CCI br4 in Lapua brass. I ran them across the chronograph and noticed my
ESs were about 100 fps for each load. I thought that was a little odd since my 6br is in the single digits and teens. Then I noticed a fired case neck wasnt opened enough to slide a bullet into it.
I was just curious if the neck may not be opening enough to release the bullet leading to my rather high ESs? I don't have the neck measurements to give as I'm not home right now.
Thanks guys!
