Berger 156s dont fit into Bergara magazine

My load data for reference

56.6 gr N565
fed 210M
hornady brass
.028 off
COAL 3.037
2962 fps
Good to know.

I've got 5lb of H4350 so im going to try and run that. I think my Coal has to be at 2.987 to fit the magazine box.

I'll have to mess with it.
 
Unless you're building a custom rifle, extending cartridge length on a commercial rifle will always be a problem. Hand feeding & single shot sleds are the answer. Reality is that the large commercial makers are never going to build outside the "standards".
