I have a lathe and mill and Rem700 rifles from the pawn shop waiting for me to rebarrel and re stock them.
But I have no intention to true the actions. Looks like fun, but no thanks. I have enough stuff without buying tooling I don't need.
I am a hunter. You name a cartridge, without a trued action, I could build a Rem700 rifle that would average 1/2" five shots 100 yards.. but it would be heavy and need to be tested on a low wind day.
Truing the action is a comparative waste of time for a hunter, compared to spending the time shooting long range targets.

If you are competition target shooter, and willing to do anything to squeeze out 1% more performance, that is different.
