I have the best luck with lighter bullet and back off the powder charge slightly as the brass will last longer.
+1, and I add a slooowwwww powder (1680) to that mix, I don't think it makes much pressure at all. Still using my original cases with my CZ, and no adverse pressure signs at all. I don't think I could get enough 1680 into the case to cause problems. I have other rifles for "going fast".
