Bullet seating question?
Reloading my .300 Win Mag and am having trouble figuring out overall length (OAL) to get correct seating depth.
I'm doing what's been suggested by several people- place bullet in brass (cleaned, deprimed), put in gun, close bolt, open bolt, measure OAL.
Supposed to be when you extract the OAL is such that bullet just touches rifling (then back off 3/1000 inch).
OAL is all over the place (I'm trying Hornady SSTs and Nosler Ballistic tips)- from 3.3 inches to 3.6 inches. I've tried it dozens of times and no consistent pattern. Tried it w/both bullets in cases that were both snug and loose.
In comparison, factory Federal Fusions range 3.287 inches to 3.294 inches out of a box of 20, and I've seen on-line OAL should not exceed 3.402 inches.
I'm thinking the bullet is getting slightly too snug in the rifling when I close the bolt. With cases that are a bit snug when I hand-seat the bullet, sometimes when I pull the bolt back the bullet is stuck in the rifling and I have to push it back out w/a cleaning rod.
I can't figger out the correct OAL using this method.
When was the last time you heard somebody say "Go ahead, it's a free country"?
