DMB and Wink man asked about 4350 for 308. I have no idea how H4350 shoots, but I can tell you that my load for 308 is 43.5 grains of IMR4350.
In the interest of full disclosure - I am NOT shooting clover leafs. But with iron sights and military style semi automatic rifles, mixed brass (including both Win308 and 7.62x51 mm military surplus brass from a half dozen countries , surplus projectiles that vary +/- 2 grains of weight, and the cheapest primers I can find I am getting 6 inch groups at 100 yards from factory rifles. If I shoot a full magazine, every bullet is on a paper plate at 100 yards. I really can�t ask for more than that.
