I'm reloading for an almost new savage 12bvss in 22-250. I've only been reloading a few months so this may seem like common sense to alot of you but I just want to do some double checking. I just picked up some berger 64 grain hollow points that I want to try out. Thought before I started loading these I wanted to check the true OAL for my chamber. Up until this point I have just been using the 2.350 standard and have had decent success but trying to learn and improve accuracy. Anyhow I used the method in the nosler reloading manual of painting a bullet with a sharpie, starting it into a once fired case from this gun that has not been sized, closing the bolt down on it to shove the bullet in the case, and pulling it back out to measure OAL to the lands. By using the marker you can tell if it stuck and pulled the bullet out of the case some so you can push it back in for an accurate measurement. First off does this procedure sound correct? Secondly the measurement I got was 2.518. Even when pushed back in another .020 to get the bullet outta the lands that would make it 2.498. That's a lot longer than the 2.350 standard. Is that normal? Just surprised me I was finding so much difference between the standard and my chamber. One last thing will having an OAL of 2.498 cause issues will the bullet not being seated far enough into the case? Thank you!
