Re: 300 Win Mag brass - best one?
I bought 100 pieces of WW brass and couldn't believe the inconsistencies in neck thickness. They were all over the place, up to .005 Winchester was good about it and paid for the shipping back to their facility, and sent me a new lot. This lot was actually worse. About 50 of them had torn flash holes from when the primer pockets were punched. After that, I returned them for the Norma.
I had a lot of people tell me to just get the Norma in the first place, but I was trying to save money. When these arrived, I couldn't believe the difference in quality. I ended up getting 140 pieces and kept 132. Most of the neck variances were .001 and the rest of the keepers were .002 The other 8 are all .003 and may end up being used at some time. I don't think you can go wrong with the Norma. They have only been through two firings so I can't give any info on longevity yet.
