View Full Version : Super .30, 2400 and cast?
I'm currently cobbling together info and equipment to start casting bullets and have decided to start with .30 caliber rifle bullets, since I have a few rifles in that bore diameter to feed. This will be, for now at least, just a source of inexpensive practice/match ammo in most of my rifles...probably using Unique in my .30 WCF and C.E. Harris' universal load (16 gr/2400) in my Krag and '06 for the VMBAR and NRA reduced course (200 yd) Nat'l Match Course shoots. I've decided on Lee's 309-170-FN for my first mold and have the load data I want for the first three rifles.
The problem arises when I search out load data for my precious pre-'64 Model 70 in .300 H&H. The only data I have on hand for the cartridge w/ cast is Lyman's
47th edition, and it lacks 2400 data. Has anyone ever tried the combinanation? I seem to think that the C.E. Harris load could work in the larger magnum cases, with possibly a filler or a slightly higher powder charge. Or is trying for a load like this in the larger cases barking up the wrong tree?

I have Weatherby's improved version of the Super .30, and have had good success with modest loads of IMR 7383 under 200 grain cast boolits. (Specifically, 4.0 and 4.3cc Lee dippers.) Haven't tried loading it with 2400, but don't see why it wouldn't work.
Would the 16 gr. universal powder charge be the right place to start? Or would I need to go higher?
Thanks for the prompt reply.
I'm buying the .311 expander die from lyman...is there anything to watch out for expanding case mouths in the .300? or .30-30, .30 Krag or '06 for that matter?
Lyman 45th ed. shows:
311466 155 gr. Min 22 gr @ 1821 fps Max 26 gr @ 2053 fps
311291 173 gr. Min 20 gr @ 1703 fps Max 27 gr @ 2057 fps
311334 193 gr. Min 23 gr @ 1748 fps Max 27 gr @ 1937 fps
The usual precautions and caveats apply. Some say that current 2400 burns at a different rate than the older versions, so use caution.
Do you mean you bought a Lyman "M" die? I set mine up to bell just enough to allow the bullet to start and seat without shaving lead. Brass lasts longer. I'd just neck size the cases also.
Cheers and Merry Christmas,

bary, welcome to the addiction.:drinks:
The most important thing you need to do first, is to get some pure lead and slug your barrels. keep the slug marked for each barrel.
The M is the one I was talking about. Still getting around to ordering it, though.
Hi B Ary,
I've long had a soft spot for the 300 H&H. It was the first magnum I ever fired. Either 1956 or 1957, after a rifle tournament, one of the old shooters asked me if I'd like to shoot his 300 H&H. It was a Win M70 heavy barrel target job. We were at the 600 yard line and I can't remember how many rounds I fired or what the score was. The old shooter has long since passed on but I still remember that day fondly.
Thanks for catching my typo!
The .30 super is the only magnum cartridge I own, and probably ever will own unless I find both a financial windfall and a pre-'64 in .375 Holland on the same day. I'm currently mulling over putting a Lyman target sight on it and taking it to the Palma matches they hold at Camp Butner, NC about an hour north of lovely Fayettenam where I have the misfortune of residing. With 67 gr. IMR 4350, wlr primer, win case and 180 gr. corelokts the old girl will shoot better than I can hold off the bench. Now if only brass wasn't so expensive...
