View Full Version : Bullet Seating

07-25-2015, 09:52 PM
I am using a SWC sized to .452" in a Springfield Range Officer. Doing the plunk test, I seated the bullet so the case is even with the hood. The front drive band of the bullet is head spacing off of the chamber shoulder. The nose of the bullet is not touching the rifling. I crimped the round to .472". Used a marker to verify where the bullet was hitting. Will this cause any problems?

Thank you,

The cartridge should be head spacing on the case mouth, not the projectile. How far above the rim is the SWC shoulder? If it's just a couple of mils it shouldn't be a problem unless you start shaving lead off of each bullet as you are shooting them.

Welcome along Vyrl, on a SWC it seems unlikely you would ever have the nose of the boolit hit anything forward but I've been having my little go round with a tight chambered 9 Luger so I know what you mean about headspacing off the front band instead of the case mouth. I found another bullet that had a nose shape for a reasonable COL I'd try another option and see if the problem reoccurs.Gp

.035". I am not sure if I need to resize to .451"

your best answer is ... try it and see.
run 20 of them through the gun.
