[QUOTE="waskow54, post: 754532, member: 62968"] I set seating depth by first seating a bullet of the type I am going to load so it's just far enough into a resized but unprimed and empty case that it doesn't fall out. I then take a cleaning rod with an extended drill stop on it and push the tip of the cleaning rod against the bolt or breechblock face and tighten the set screw on the drill stop. Then I put the case with the bullet into the chamber and press the bullet gently against the start of the rifling. I put another drill stop on the cleaning rod so it's between the first drill stop and the muzzle. Then I push the cleaning rod into the muzzle until it is against the bullet tip. Then press the second drill stop tight to the muzzle and tighten the set screw. The distance between the drill stops is the loaded cartridge length if the bullet were to be seated against the rifling. You can use this length to seat your bullets a known distance off of the rifling simply by seating your bullets for a shorter total cartridge length. You can check your measurements by seating the shorter total length cartridge and then putting the cleaning rod tip against the bullet tip tightening the first drill stop then putting the longer seated bullet in the chamber and putting the cleaning rod tip against this bullet tip and tightening the second drill stop. The distance between the drill stops will then be the distance the bullet is seated off of the rifling. You can start at a short distance off of the rifling-.025" load three or six rounds at that length and check accuracy. Repeating this at .005 or .01 intervals until you find the most accurate seating depth. Note don't do the length checks with loaded ammo! I use unprimed uncharged cases. [/QUOTE]
