My favorite in several .338s for more than 30 years is:
73 gr/IMR 4350
Fed 215
210 gr Nosler Partition
Winchester or Nosler brass.
That sounds like a load I'd try....How fast are those running? Probably pretty close to 2,900 huh......
Right at 2900 fps...I never really did a work up with H4350 because IMR4350 worked so well, but the Hodgdon's may be better yet. I just know that this load has worked in five rifles I had over the years, and the one that remains.
