Hi Guys:

A while ago I bought a 375 H&H mag from one of our members on the board. It was a Winchester Mod 70 SS, stock barrel, CRF action, in 375 H&H mag. I wanted a 375 to round out my collection.... good excuse huh.

Anyway, this rifle had a sort of long muzzle break about 3 inches long, on a short barrel, total barrel lenght 23 inches to end of break. There was a trigger job that broke cleanly a 3lbs.

Started with Factory Remington Safari Grade Swift 300 grn, not great but 2.5 inches at 100 yards. So decided to reload for just one more caliber.

Anyway, this puppy shoots. The recipe I used, is IMR 4064, 71 grains, Federal cases, CCI 250 LRM primers, 270 grn Swift Aframes, Shoots (3) shots 1/2 to 3/8 in groups at 100 yards,Six shots average velocity @ 2710 FPS, extreme spread of 6.68, and standard deviation of 3.46...

Anyway I was impressed with the IMR 4064, because this is the powder I use in my 416 Rem Mag, with Swift 400 grn. @ 77.5 grains..

Just passing on some info...

I'm going to work-up to the IMR#4064 load you posted. I heard that IMR4064 was the powder used in most commercial .375 H&H ammunition. Another versitile powder is Winchester 760. My favorite load for 300 grain bullets (Hornady, Sierra and Combined Technology) is 76.0 grains in WW cases, using CCI 250 primers. 78.0 grains with the same cases and primers with the Hornady 270 grain spirepoint is another good load. Good luck with your .375 H&H.
