Pre-fit Lemmon? What’s your thoughts

I use it in my ARs. I can wad up a 30 round mag in 1MOA with my loads.

BLc2 = wc846= CFE223 without copper erasers

You don't use the go gauge on an AI chamber unless that is what you asked for, some have the .003"-.004" negative headspace on the go gauge, others do not.

Cheers.

The 223 go gauge becomes the no go gauge on 223 AI
Tikkas have generous gap between back of extractor and face of bolt,with plunger ejector,plunger keeps the case pushed foward during ignition.
Controlled round feed actions can,most of the time form long chambered AI's,somtimes might not get sharp shoulder,extractor holds case head tight against bolt face,shoulder goes foward even if chamber is a bit long,brass will only work in that chamber.
Did most AI's in early 80's,fireformed a lot in prarie doging with cheap canister powders and bulk bullets.
