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.
Not with the mixed components you are using, but if you switched to one brand of brass, bought some decent bullets and possibly primers you could shrink group size significantly. If you would be interested in such a thing?
