Hi all! I am loading .300 Blk for my AR. I have loaded 100 rounds using my RCBS 7.62-130-SPL mold. I am resizing to .309 using my Lyman 450 with RCBS Rifle bullet lube. I have not shot lead through my AR yet. My question is do I wipe off the excess lube above the groove?
Thanks
If it's on the bearing surface, leave it there. Wait to wipe any lube off until after seat/crimp. No sense having extra exposed lube gumming up things.
So after I seat/crimp. Wipe-off the exposed area?
You can. You might try not pushing it so deeply into the die......
I'm seating/crimping the bullet just below the grease groove. The groove is just exposed above the case mouth. Do most of you wipe-off the excess lube above the groove or grooves?
AFTER I have seat the boolet in the case and have applied any (if any) crimp then and only then do I wipe the excess off the OUTSIDE of the case neck and not the boolet.Robert
Thanks!
Your pictures would help...

These boolets appear to be tumble lubed, but the lower lube grooves, ordinarily filled, are seated within the case neck, and the case neck is crimped (if any) into the bearing surface (in this case).
If the lube groove is exposed, and you carry the rounds in a pocket, the lube will tend to pick up grit. Shooting grit down your barrel may accelerate barrel wear, but it would take a heap of shooting to do that.
Tom W's advice above is best for you. Do not size the round so deeply in the die, which allows lube to go above the ogive. If you have "a glob of goop" on the bearing surface of the bullet, you should wipe it off.
Not every groove is meant for lube. The grooves nearer the ogive are crimp grooves, wherein the case neck is crimped into the groove such that magazine fed rounds (like the AR 15) don't get pounded back into their cases by recoil slamming them into the magazine body.
