[QUOTE="Hand Skills, post: 1505270, member: 103303"] Thanks for following up! How does your rifle shoot with factory ammo? One thing to keep in mind is the difference between chamber and magazine. CHAMBER does not care about OACL. CBTO is what matters. MAGAZINE does not care what CBTO is, but it does limit OACL. One thing I like to do when loading for a new rifle is to find the lands. I make up a 'dummy' round (no powder or primer). Just a bullet in a case, seated out really far, I'll slowly increase the seating depth (half turn at a time) until I can close the bolt on the dummy. This indicates where the lands are. For a precise measurement, I use layup die/smoke residue/jiffy marker on the bullet so i can see the points of contact with the lands. [/QUOTE]
