[QUOTE="Buck Buster, post: 1392643, member: 99718"] You are correct : The powders listed for its best loads are 4350, 4831 that I use and H450. The 300 win. mag. and the 308 Norma mag. were both developed on the 338 Win. case and loads and fps are very close to each other. The shoulder on the win. was moved forward to lengthen the case capacity and left a shorter neck. I also have a carry gun in the 300 Win. mag. and use this powder in both of them. I load 77gr. of 4831 and a 168 gr. Amax in the 300 Win. mag. manual puts it at about 3200 fps.; I tried heavier bullets when I was working up a load, but the Hornady 178gr. Amax beat the next best ( 190 gr. Sierra BT match king ) by a smaller group of over 1" at 300 yards, so I went with the bullet that shot the best group. I don't think I would have much more to gain, the heavier bullets may give me a few more yards down range? But they will also be starting out of the tube at a slower speed. I am satisfied with the distance it shoots. If I want to ever shoot farther I will go bigger, 338- 378 or the big 50 cal.; I don't see that happening. Hope your out of the snow for the rest of the year. Good luck hunting and shooting in 2018. [/QUOTE]
