[QUOTE="vonb, post: 188947, member: 8910"] If you look at the specs of the Borden Alpine vs. the Rimrock, you will notice that the Rimrock actually has a tighter bolt/receiver fit. Rimrock Action: [COLOR=black]"[FONT=Arial]The (Rimrock) actions feature the patented “Borden Bumps” that result in a very close bolt body to action bore fit when the bolt is closed ( <.001" diametral clearance)[/FONT] "[/COLOR] Alpine Action: "Bolt Body to Action Body clearance <.002 inch" If you are going to hunt with it and are worried about dust/grit, I would go Alpine. If looking for a target grade action, go with a Rimrock. I was up against the exact same choice as you and went with the Alpine for a .223AI build. [/QUOTE]
