Just last weekend I worked up a really nice plinking load for my Ruger No.1 in 375 H&H Magnum.
Projectile: 255 grain RCBS FN GC mould - throws a 261 grain projectile with wheel weights plus 2 percent tin Sized to .376" and lubed with SPG lube
Powder: 33 grains ADI-BM1
Wad: 1x grey foam wad 1/2" x 5/8" pressed down nicely onto the powder but not tamped down too hard
Primer: RWS 5333 Magnum primer (only used these cause I had a couple of hundred of them sitting around)
Case: Kynoch
5 shots Chronographed at 10' went as follows:
1566 1565 1576 1564 1573
Average of 1569 fps ES 12 fps
100 yard group for the 5 shots 1-1/8" (4x Pecar scope fitted just for group testing)
With the open express sights I can keep 3 into an inch or a bit less at 50 yards all day. No visable leading after 30 odd shots. Had great fun busting clay targets with it at various ranges out to a hundred yards or so.
Nice load, very accurate, very mild and very useful. Kills our wallaby neatly with no fuss at all, just bang flop. So far so good. I think I'll enjoy playing with this.
Same caveats as usual with any loading data, my loads, worked up in my rifle, start lower and work up etc etc.
