Welcome Halesy404.

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.

Hope this helps

Best
