Is there a downside to having your headspace set at minimum?
I just did my first barrel swap on my savage 308Win. I use the gun for shooting groups and long distance.
I think I have the headspace set almost EXACTLY at minimum. The real question is do I WANT absolute minimum.
Go gauge, FGMM, and new Lapua brass closes just fine. My used Lapua that I full length sized closes tight (+0.0025"). I may need to try resizing again with a strong cam-over to get the used brass down to size or will need to switch to a separate body and shoulder bump die. I would expect the dies should bump my shoulder back to minimum
I have never heard of anyone wanting to increase the tolerance on their headspace bit thought I would ask those more experienced.
1.6200 - 1.6210: go gauge
1.6195: FGMM
1.6200 - 1.6210: Lapua new
1.6225: Lapua used and resized
