50/70 bullets

[J.B.]

This has been my experience as well Kurt but I've barely touched on pp as you have. I do like to have cases that run the full chamber length but this seems impossible with commercial cases unless one buys the larger size and trims back. At the cost of brass I'm reluctant to trim back 50/90 cases to suit. As you said though , I've found as long as I'm aware there may be paper rings, I allow for it and of course wiping removes the variable anyway. The 50's just dont seem to be as fussy as the smaller cartridges ..or so it seems. The RMC cases I obtained with thicker necks, didnt produce the rings but then they were trimmed to exact chamber length and at .016" thick at the necks...didnt allow the paper anywhere to go but forward with the bullet. There was no guillotine action happening on transition. Knowing what I do now I probably would have asked for a shallower chamber end but it still shoots better than I can hold. ... Actually they all do
