Shortly after the WSM’s came out I had a Ruger #1 made up into a .338WSM thinking that I would be ahead of the curve 🤣WRONG! They brought out the 325. Oh well. I am currently working on 250 gr load for it. Should get in neighborhood of 2650 from a 24” tube. Will be my son’s Africa rifle.

I’d love to learn of the powder and charge thereof that nets 250 gr @ 2700 from an 18” barrel in the 358WSM That would be sweet!
