I read that article in handloader too. I think he has other problems going on. While I have seen a few loads with the crazy ES's he is writing about, it is anything but the norm. You can see in my post above, I just am not seeing any huge differences between primers, and I'm not seeing huge ES's. This is with pretty much any bullet. Where I was seeing problems was with light bullets 100 grains or so, with slower powders. That's half the reason I kept going up in bullet weight.
There will never be a conclusive, all encompassing answer on what primers to use, and when. I use Federal standard primers with the 310 grain Lee in 44 magnum with H110. It performs the best. And here we are seeing some spectacular results with small rifle primers with flake powder in the 327 federal.
One problem I ran into with Starline brass in particular. It seems the annealing is questionable on some batches. I could feel bullets seat to different forces between each. I think Brian Pearce is looking in the wrong place.
Starline exchanged all my new brass for free, and the new stuff is much better.
