[QUOTE="Savage 12BVSS, post: 1808248, member: 112413"] OK boomflop, I'm give you my humble opinion on this, I been loading and shooting my 22-250 for 17 years and you know what? Till this post I never so much as gave a thought to how far in the case it was seated. I just went down and checked it and I use 50gr boattails that are .774 long they are seated in the neck .134. You couldn't pull one out with your fingers if you tried, I did. Heres what I do with every rifle I load for.. I put the bullet in a dummy case (one of the cases you use, just no powder or primer) for that caliber. Seat it in your seater but leave it hang out nice and long. Then gently close it in your chamber and close the bolt, Than pull it back out with the bolt and measure the overall length.
