My CZ 458WM has never seemed to like light bullets but will shoot MOA with 450gn and heavier jacketed or TSX, so just tried some Oregon Trail True Shot 430gn FPGC .459 diameter cast. Worked up to 66 gn of Varget, crimped with a Lee FC in the first lube groove, 3.015 oal, the gas check is touching the powder. Got groups around 1-3/4 inches with point of impact within 2 inches of my go to 450 TSX load (Lott length) at 100 yards. Haven't chronoed them yet but they are stout, primers show some flattening and no ignition problems. Just what I was looking for, reasonably priced practice loads with POI close enough to leave the scope alone. US $22 for a box of 50 bullets, plus shipping. Only fired about 10 rounds today, but this load looks promising in my rifle.

This load was OK in my rifle but do your own research to be safe.
