Hello,
Does any one have loads to share using R15, H4895, H414, H4350 and the 180 Bt Nosler in the 338 Win mag. I am trying to decide on a powder and have used all these before but not in the 338 can anyone help. and I do understand that all rifles are different. This load will be used for white tail and mullies.
Thanks for the come back.

My Choice is the H-4350 loading.

I am using 68.0 grs. of RE 15 with Fed 215 and seating the bullet .020 off the lands. I am getting around 1" with this load. I will use this combination on a late season cow hunt in 3 weeks and I'll let you know how the bullet performs.

During initial load developement I tried H414 but this powder did not group as well. If I had more time before the hunt I would have liked to try IMR 4350 but the RE15 did well within minute-of-elk so I just stayed with it. The recoil is minimal as well. This is the only bullet I've tried in this rifle and I can't wait to try some 210 Partitions.

My old standby with the .338 is some original surplus 4831, which is some bit slower than the current crop of 4831's on the market -- actually, almost as slow as IMR 7828. It has done well with bullets of 200 grains and heavier, but my preliminary work with the 180 grain Nosler BT indicates that a faster powder is needed. I'm going to try VV N160 first, since I have a quantity of it, but any of the 4350's, H-414 or WW 760, RL-19 and other powders in that range should be useful.
