Impact Precision’s action has more primary extraction built in than most other actions. This means that you can't push the bolt as close to home when you run it forward as you could on a standard REM 700. The con is a little more "cock on close" if you run the bolt slow motion. If you run the bolt like a man, you will never notice it. The PRO is more primary extraction. It is similar to shutting a vehicle door at normal speed vs slow motion. Run that bolt!
