I purchased a tumbler that uses stainless steal pins. I have been tumbling my brass until its "squeaky" clean. It satisfies the OCD part of me, but now bullets are hard to seat and I get quite a variation on my length to ogive. I think this is due to the "squeaky" clean brass and the bullets "Barnes" having a lot of friction because there isn't a small residue of carbon. Its hard enough to seat that I think it might slighty changing the overall length of the brass during sizing. I am chamfering and sizing for .002 of neck tension.
after a few conversations with the folks that made the tumbler I will now only tumble about 40 min, but I have brass (nosler) that is sized and ready to load. I was thinking about dipping the bullet into Imperial dry neck lube to make it seat easier on that ultra clean brass. My only concern is that maybe during recoil the bullets in the magazine might be more apt to move in the case. Shooting a 300 Win Mag (with a brake)
Thoughts?
