[QUOTE="Mateo, post: 1449648, member: 77067"] I was still on my original 100 pieces of NORMA 300 scum brass when I burnt out my barrel. well.....some of the original 100 I'd had to cull about half of them due to loose primer pockets. I then retired the rest when I pulled the barrel off. I was having trouble with annealing the necks. I think I over annealed them even though I was careful and used tempilac to get my timing down. I'm gonna bring them to someone with a proper annealing machine and see if they can be brought back to life. they held bullets fine it's just that the neck tension wasn't consistent anymore. I could feel it when seating and also sizing. I found some Remington stuff for cheap and have been using that. however my scale went a little nuts (gem pro 250) and was wandering like crazy. I still loaded with it while constantly recalibrating it and that's what I used to break in the new benchmark barrel. once I fixed the scale I weighed some of those loads I had been using and discovered I was shooting some hot loads! 1.6 grains over what I usually shoot. and now I've noticed a few loose primer pockets already. oops. strangely enough, it shot fairly well and didn't show much for pressure signs. The odd one had a stiff bolt and a bit of an ejector mark. I'm thinking those where a bit higher in charge weight. As for seating depth, I use 2.930" with the 140 VLD-H and keep that same seating adjustment with the Matrix 150 gr bullets. I'm playing with 140 gr chinchaga ULD's with a rebated BT. we'll see if I can get them to shoot. [/QUOTE]
