I'm looking to buy some Norma brass for my .270 wsm. I understand that this brass is thicker and therefore stiffer. Does this create higher pressures and as a resultshould I back off my loads a bit????

So far my best (Great)accuracy has been with 59 grains of IMR 4350 in once firedWin. brassand I'm reluctant to change anything.

Thanks,
Bill
