Medriver,
Yep 350-360 grain bullets are just right. Was enjoyable to shoot with rl 10x handloads, from an 8.5 lb scoped rifle.

In the 416 ruger, I'd like to use the same bullet weight.

But the 400 grain factory dgx bonded stuff is just too simple to pass up. 2450 fps from a 22.5" barrel, over the chronograph.
