Prefits are the way to go if available for your action. I've done numerous now. Origin Bighorn, Defiance Tenacty, 2 Kelby Atlas, Etc… The tolerances on these actions are so precise and repeatable. I used shouldered barrel prefits on all mine and all head spaced perfectly. The only issue that can arise is when you want a chamber throated for a specific bullet. Most prefits are going to be throated to SAAMI specs. Proof now offers some, PBB and RaggedHole do them as do numerous others.
The issue you run into after truing-blueprinting the newer RR prefix Remington actions is a PITA. They lack primary extraction and after truing it gets even worse. Correcting it can get costly. Did it once and never again.
