If, I manage 2350 fps with the 404 Hammer from my standard SAAMI 458 Winchester with 22" barrel, I should have a few fps either side of 1900 at 230 yds.
The 230 yds is my target of "long-range" bullet performance. I "think" the 2350 fps muzzle velocity will be easily obtained. I am staying conservative / reserved on my guesses, until I chronograph this rifle.
My optimistic side says 2375 Fps will be no-sweat condition achievable. The 404 Hammer bullet is #1 !!
