[QUOTE="tooele, post: 504668, member: 31853"] Having some trouble with getting a length with the 210 berger bullets in a 300 rum. I am getting real consistent measurements with the Hornandy OAL gauge. THe length is too long for the magazine, so have made the max length what will fit in the magazine. So I seated bullets in the cases X 3 at the determined depth. Started cycling the shells. The Bolt was very difficult to close as if I were shoving the bullet into the rifling. So after a tough time getting the shell out, I remeasured and indeed the bullet had been seated deeper into the shell. With a comparator, original OAL with Hornandy was 4.47 repeated 10 times. Shell length to fit the magazine was 4.211. After feeding the bullet and extraction the length was 4.185. Same thing on all three shells. Each bullet after extraction was marked. So what is the problem here is it the Hornandy shell casing compared to a normally sized casing. Have a hard time believing it is my technique as it is very reproducible? Is it the Berger bullet? There is a big discrepency between the Hornandy OAL and what the rifle determined is the actual OAL (4.185). Any advise help would be appreciated. T [/QUOTE]
