Have you tried it out at 800m yet?
You will likely see a difference in performance at long range between a trued and untrued factory action.
If you never shoot out there, you can enjoy your tack driver as is.
As for DM systems, my buddy and I just won the CF sniper competition and never loaded a round in a mag. Food for thought.
Welcome to the sport.

I never load a round into magazine anyway, but most of my rem700PSS does very good at 100meter, and generally does very well out to 500meter, last weekend on Sunday, we try to shoot out to 700meter figure 11 metal gong, the last 5 round hit on to center mass, while the first 2 round miss because of the wind. is just my opinion that Truing the action is not necessary, what make the gun shoot good is the Quality of the Barrel is the first biggest thing, then putting them on straight is another, the rest got to do with reloading.
