Guys I have a question to ask please? I have a custom Mauser in 308 win, and I reload for it. The problem is the neck of the fired brass has burnt powder residue all around it. Am I doing some thing wrong here? Am I not seating the bullet out far enough or maybe full length resizing to much, and getting shoulder bump? The rounds do vary well for me out to 300 and 400yrs, but at those velocity's getting out any farther is pretty much a lob. I am a casual bench shooter and really have no need for any longer shots.
Any comments or suggestions will be appreciated!
Barrel is 24in" Shilen heavy bull, 1in10 twist, it likes long heavy bullets, can get 3 round bug holes at 100yrs
Bullet= 180gr SST
Powder=39grs of RL15 best load for groups, Hornady book says max for RL15 is 41.4gr at 2400fps out of 20in" Barrel.
At 40grs I start to get flat primers, at 41gr I start to get shinny's on case and heavy bolt.
Cases=Winchester new or once fired, full length resized and trimmed to 2.015
Primers=Winchester LR standard
COL.=2.750" book says 2.740" Should I go to say 2.800?
Vel. avg.= 2364fps chronographed at 10' from Barrel
Thanks Marvin
