I've got a DT and a Ruger precision if you'd like to try before you buy.

As far as the bolt manipulation goes, that must be that guys issue. I ripped through stages faster than most of the guys in my squad at the last T3 match. I've got a 10 rounder for my Creed conversion that runs flawlessly. And as said previously, I can switch to my 338lm conversion in less than two minutes and have an MOA change in POI.

ColoWyo, you just swap out the bolt, barrel then put the corresponding magazine in and go to town.
