ole 270,
I have used H-335 and WC-844 (H-335 burn rate) in my Model 94�s with the 311041 bullet. In my opinion, these powders are too fast. Yet the WC-844 works very, very well in my 7-30 Waters with the 287346 cast bullet�go figure!!! I have found that with the 311041 and the 30-30, the slower powders work much better. My best load for the Model 94 and the 311041 is with WC-852 (slow lot). This powder has a burn rate in the 4831 range. Velocity is only at the 1800 fps range, but the �scoped 94�s will rattle brew cans filled with water at 100 yards most of the time. I think a slower burning powder might work better with the 170 grain cast bullet. A side note: H-335 is my powder of choice for the 30-30 with jacketed bullets. Both the 130 SSPSP bullet in the T/C Contender Super 14� and the 150 Hornady Round Nose in the Model �94 shoot extremely well. Again, I think a slower powder might perform better for you. Good-luck�BCB

Yes...
I used the Lyman 311041 in '94 Black Shadow with exactly 30 gr. H-335 & CCI 250 Magnum primers & boy does it shoot! A guy who is pretty much one of the main Gurus on this board told me that this powder needs to be loaded pretty near max. to shoot uniformly & it seems he was right. The bullets were dropped right out of the mould into a bucket of water so they are somewhat hard. I sized them .310" & lubed them with Lee Liquid Alox. No leading at all either after 20 shots. Went on to shoot a bunch of others treated the same way & still no leading after about 100 shots. I think the size, hardness, right powder combination all have something to do with it for sure.

H335/WC844 have various lots out there which are at least a grain apart in speed when shot in a 30-30 size (36 grains of a very fine ball powder to neck) case. Naturally, we are talking top loads here. Lever guns typically have an abrupt land protrusion, and this can increase starting pressures beyond normal especially with a powder known to be on the fast side. Also, an overly tight hold on the boolit in the case before firing can work against us. Plus, a hot primer. Getting all three reasons to gang together and we have a resulting pressure equivalent coming on way to early for the gun. Normally, the H335's, plus and minus, represent an ideal speed for the 30-30, but in your situation, going to a slower powder would not be out of the question. Any 748 or BLC2/WC846 on the shelf? I'd select a final powder that would consume 28 grains or better for a "full" load condition. ... felix

My feel is that H-335 has a bit more than the usual lot to lot variances and that it is a bit touchy as you near top loads. I've shot a good bit of it but mostly in .308, .223, and .250-3000. The early data for it had big spreads, and I ran into a grain and half difference in top 150 grain .308 loads between two lots.

If memory serves, Lyman tested a lot of loads with straight lino. Your WW bullets might be just enough heavier to make a difference in a load that is already hot.

Were I you, I'd give those bullets another coat of LA and start over at 24 grains, working up very carefully.

To the fellow who damaged the Rem 78, one possible cause would be that a fully annealed case somehow got mixed in. There were some of those floating around in the mid '70s and a perfectly normal load would expand the case head enough to damage rifles. I was a bit luckier and only lost the extractor off a Savage 110 to a moderate charge of 3031.
