Ditto to what Huntr sez... I shoot 50.0 grains of H4350 in my Ruger #1 International (aka "RSI") as my "hunting load". That's a
MAXIMUM LOAD according to the Speer Reloading Manual #13.
I haven't chronographed this load yet, but I don't think this load quite makes it to 2800 fps outta my RSI's short 20-inch barrel, but it comes close... I'm guessing probably about 2785 fps or so.
However, in their testing, Speer's test rifle had a 22-inch barrel for this load and achieved slightly
OVER 2800 fps.
My RSI fired a .404 inch, 3 shot group at 50 yards with this load behind 140 grain Sierra ProHunter, flat-based bullets sparked by standard Winchester large rifle primers in once-fired Remington cartridge cases. I noted that recoil was up (but not bad) as was the noise level, so this is 'most likely a true "maximum load".
However, there were no pressure signs and the empty cases extracted easily... but that load is a "whomper" for sure!
Strength & Honor...
