I'm using the Barns TSX 285 grain with 106.8 Grains of Vihtavuori N570 getting sub 1" groups at 100 yrds @ 2868 FPS

Cool! Welcome to the nation!

I'm not the most verse loader but that seems on the lower end of velocity for that grain? wby loaded ammo in 225 ttsx showing 3180 at the muzzle.

We slowed some a-frames down in my 340 because they were so accurate running about 2850 - but you could almost put 2 in the same hole and all through would be touching somewhat. I'll take that to a certain distances any day!

Welcome to the nation - she's not a cheap one to load or shoot for, but 338-378 is prob next on my list;

Welcome to the Nation.
A buddy uses his own handloaded 236 grain Hammer Hunter bullets with his 338-378 Wby. I don’t know the muzzle velocity but he drops elk on the first shot.
