yes, you can. I've been arguing with John since the day he opened shop. But right now, today, I can and do send him drawings with exactly the numbers I want on them and he hits them. Basically I do less than half of the sizing effect that he calls for, and IMO setting the shoulder back two thou is absurd. I go for a half a thou of shoulders set back if I'm shooting the rounds immediately and a thou if the cases will set for days/weeks. His dies are also hardened now, this is huge. Un-hardened dies are an abominationWhat dimensions do you get after sizing brass, in relation with your chamber? Whidden says they take off .0025 with .001 spring back and approximately .002 shoulder set back. Just wanted your thoughts how they perform. I like the idea of minimal working of the brass. Can you request tighter tolerances ?

Un-harden dies ? That's crazy ! LOL I'm dealing with my Redding standard seater with .470 or so at the base..... I don't have pin gauges, so I'm not totally sure and any FL die is way under even when I bump my shoulders at .0025. Anything under that is a bit stiff. But I would love to use his dies. What kind of clearance can I go to for function after firing ?
If you're talking about a "typical" .308Win-based case and a typical (not fat-butted) chamber I'll suggest 1.5 thou @ shoulder and 2 thou at the base.
I don't get carbon rings and wouldn't reload tight if I did.
Perhaps it's safer you go with Whidden's recommendation.
I let it go a bit too long LOL live ya learn. Usually clean well, but didn't realize that ring builds up. Know now.
If the rings doesn't accumulate then I could load tighter ? Or is a Sammi chamber different than custom chambers ?
SAAMI is a governing body which defines minimum and maximum sizes to 'standardized' cases
"Custom" can mean anything.
I shoot very few chamberings which fall inside SAAMI definitions..... yet many of them will still fire and function initially in a SAAMI spec'd chamber.
nois it important to have a case head fit snug when in a seater die ?

hardened... heat treated hardened, I take it.

Any suggestions to go below .002 shoulder set back? I'm probably missing something. My bolt handle is to stiff for me below that.
In your situation I believe you are stuck..... if it were me I'd pull the barrel and hone the rear of the chamber out a thou or so but I'm not normal. I believe in attacking the root of a thing. And the ROOT of the thing is that your die doesn't fit your chamber.
