When I build my gun, I made the head space so that it just barely closed on a go gauge just to be safe as it was the first one I had done. Im looking for a little more capacity and I was wondering if upping the head space so that it just barely DOESNT close on the no go gauge would be acceptable.

I understand that normally if you FL size every time with more head space, this would shorten case life but my thoughts are to add .001 shims to the die and glue them when I find the correct amount to push the shoulder back slightly. Ive found with some of my hotter loads that they have to be FL sized or they don't chamber well. Maybe it doesn't even make a substantial effect though. I just know im crunching powder if I seat .005 from the lands with less than 42.7 gr of 4064 and 175 smk. I think I start crunching around 42.3 or so
