Thread: Rounds jamming into lands

your issue ISNT the neck..or projectile...its more than likely the body of brass itself/shoulder...bump it back more and issue will simply go away...as will tight chambering.....in effect you trying to park a station wagon into a parking space just big enough...try it in mini and its really easy....try it in slightly smaller station wagon and happy medium is found.

partial length resize...sizes MOST of neck and some of case...it bumps case back a little..but not all the way true F/L does...its a bit of both sizing methods...if you dont screw die in enough you can sometimes see ring on neck where its down to...really shows up on 7.62x39mm if using 308 projectiles and sizing button..sort of a mini double shoulder... extreme eg to describe what I mean.
