32 ammo

some years ago the American Rifle man came out with a very good article about the 32S&W long. in this article were some recomended loads -one in particular I used be have misplaced the info; it was loading OO buck as the projectile. can anyone give me some info on this load.

I don't know the particular load, though 00 buck for either .308 or .311 squib loads is an old time idea. It is .33 cal, if I recall correctly, which would be about 54 grains if pure lead (I don't know the actual alloy density). It stabilizes well in the rediculously slow twist rate standard in .32 Long barrels (18.75", same as .357, .41, .44, and .45LC; 12" has been shown to be much better (with wadcutters in particular)).

I don't know the particular load you refer to? I tried several in my internal ballistics program based upon seating the shot down flush with the case mouth. None of the usual pistol powders like Bullseye or WW231 would burn very completely in 4" to 6" barrels (50% to 75%). The only powder I have data on that did well in terms of burning and ballistic efficiency with this light little projectile was Hodgdon Clays. 1.8 grains of it gave about 1000 fps from a 5" tube and burned 99.75% in the tube.

I would give this a try. Peak pressure with Clays was achieved with 2.2 grains in a case with 14.8 grains of water capacity, but you only get another 140 fps for that, and may be stripping lead off if you do. I would start at 1.5 grains of Clays and work up, watching for leading.

re-OO buck load

Nick:
I appreciate your reply to my quirey(sp) about using OO buck in the 32 S&W Long. The article that I was refering to, that came out in Rifleman, was over thirty years ago-I called Hdq. NRA and was told to put me inquirey in writing.
As i recolect, the load was not to accurate, just a plinking load-cheap and fun to shoot.

0 Buck should be a better bet. 00 will need to be run through a sizer.

I cast WC for the .32 S&W Long, but the Hornady swaged HBWC are very reasonably priced and extremely accurate.

Actually, buckshot is made by a much less precise method than bullets. As a result the tolerance for buckshot is +/-0.015". So, even though the nominal diameter of single-ought buck (0.32") is closer to .311" than double-ought's 0.33" nominal dimension, some single-ought will be as small as 0.305", and will fall into the cases and allow gas blow-by in the barrel, causing leading.

You could try running the bigger balls through a sizer, but I think it would be hard to keep the small cylindrical bearing length that results from tipping off axis during seating. Try it to see? The powder will have no problem pushing the oversize ball onto the rifling, but if the largest balls swell the cases to the point they won't chamber properly, you could remove the de-capping pin from your sizing die, then run the loaded rounds up in there to size the ball and case into spec. You would do best to have a carbide sizer for this. Otherwise you will have to do a bit of lube cleaning.

I would still recommend you seat the balls flush with the case mouth, then apply a little bullet lube to fill the space left around the edge of the ball. You could also apply Lee tumble lube to the balls and let it dry before loading.

By the way, like Leftoverdj, I like cast wadcutters in .32. I bought a six cavity Lee mold for their .32 tumble-lube wadcutter. Very accurate bullet. My dad had trouble with hollow base wadcutters keyholing from his GSP, but not the tumble lube bullets. An article appeared a few years back in which the author fired .32 HBWC's through a series of barrels with faster twist rates. The groups were tightest when he got to 1 in 12". The shorter cast wadcutters (no hollow base) stabilize more easily in the slow 1 in 18.75" standard twist. .32 H&R magnums have enough extra velocity so this is less of a problem for them.
