I have been looking for data for a friend of mine looking to load the 350Gr TSX in his 458 Win. My Barnes manual, and even their website doesn't have any loads. Anyone out there with experience/loads?

I've tried a few loads, but have settled on 71 grains of H4198 in Norma brass for 2600 fps in my Winchester. 69 shot clover-leafs at 2500, but 71 shot to the same 100 yard POI as my 450 grain A-Frame load. Over that accuracy started dropping off but pressure still wasn't an issue. I wanted a lower recoiling option for a buffalo cull hunt I'm doing, in case a recoil holiday is warranted. I also am curious to see what the light bullets and higher speeds do on water-buffalo.

This article might be fun.

H4198 gets away from annoying compression problems when loading, and I can get it in Australia.

Thank you! You gotta love AR. I had help in seven minutes.
