H-335

[Mitty38]

H-335 is my holy grail for my .223 wild AR 15 with a 1-8 twist .
Seams like if I am loading Jacketed bullets for varmintering, anywhere between 55 and 63 grain. There is always this spot on, sweet spot that is a half grain of powder wide. Find the middle, set your measure within .2 of the middle, if it drifts a bit you will never tell.
What I am wanting to know is has anyone played with this powder using cast, in any caliber. What are your thoughts.
Educate me.

No cast work with H-335/WW-748. It is the SCHIZNIT in 223 and 308 using the redcoats AFAIC, but low density loads with ball powders don't give me the warm fuzzies.

I suspect it would be all right in 30/30 WCF, since the caliber reaches its velocity apex at the top end of conventional cast bullet capabilities and has pretty good densities while doing so. It is decent in jacketed 30/30 loads as well.

 

[Mitty38]

I was thinking it might make a good 45-70 heavy cast bullet hunting load. Of course, shot in a newer Henry or Rossi steel action, or a bolt action.
Or maybe a 450 BM Ar-15 in cast? 2200 fps is its standard velocity, that's not too far from 1800 fps, and I have witnessed that being done with cast. Maybe it could be done with a gas checked, powder coated,350 grain flat nose bullet?
I have saw 30-30 data but never read of anyone's experience with this powder in cast.

My "magic" powder for the 223 is H322. Loaded with a 52/53g Match bullet I have yet to see a gun that didnt shoot it well.
Many great powders, just as many favorite powders.

Here's magic for you. .222 Remington, 22.2 gr. H322, c.o.l. 2.20" Hornady 50 gr. V-Max. Deuces all over the place.

First powder I got for the 30/30, works fine with cast. Good in 308W too.

 

[oscarflytyer]

Have a 335 load trying in the 358 Win. I use it for my jacketed 35 Rem load.

 

[fiver]

it's too slow for the 45-70, the expansion ratio will kill you.

 

[Cherokee]

H335 is my powder for 223 and 308. I've used it in 30/30 with the RCBS 190 RNFP GC with good results for me.

 

[waco]

I use H335 with a Lee 55gr cast bullet in .223
19gr gives around 2060fps. It cycles my AR and holds the bolt back on the last round. I can bust clays out to 70 yards offhand pretty easily.
I am rethinking my powder choice now. I heard some talk hear about downloading H335 is not a good idea......

H-335 is my go-to powder for maximum performance with cast bullets in .35 Remington and 5.56. I use jacketed load data for equivalent bullet weights.

Is H335 a twin to WW 748?

 

[Mitty38]

Correct me if I am wrong, going by memory here, but the load data varies a bit between the two.
I used WW-748 in my .243, a bit. When I still had it.
It seamed to be like H-335's slower brother.
Like a step down, giving those heavier bullets a longer steadier push out of a longer barrel.

 

[Ian]

I'm not aware of the two ever being interchangeable or "the same" like H414/WW 760 and H110/WW296 and HP38/WW231 which are in fact the same powders now.

I will say that 748, H335, and Ball C-2 are all very similar and their respective burn rates have varied so much between lots over the years as to actually overlap.

 

[S Mac]

I think that answers my question, now that I think about it maybe I've seen both listed in load data with different #'s, ie charge weights. Never had 335, do have a few lbs of 748.

 

[fiver]

there's a little family of powders right there that were originally govmn't type over runs or surpus close-nuff's to sell off to the public under one name or another.
blc-2 [and 1 at one point only with another name] 335, 380, 748 and many of the WC's [that come hot and cold for tracer ignition] all kind of scatter plot in that burn speed between 4064 and 4350.

so data of course would overlap, and probably only varied due to powder shape and lot discrepancies such as who [which shift] added the burn deterrent on that batch.
anyway with all the variables your really looking at a 2~maybe gr. [at most] variance window between the whole pile of them using the same cases and bullet weights.

 

[hrpenley]

335 and 322 both always performed well for me with cast, 223/308/7.62x39

 

[hrpenley]

748 is my break-in and test bed powder for a number of rifle calibers, all 3 can be downloaded pretty well, good consistency when dropping below published book loads. The only issue I ever had was 748 doesn't burn as clean as the other 2 which is really not that much of an issue as far as I am concerned. Especially when its 10 bucks a pound cheaper.....

 

[Ian]

748 never worked very well for me when downloaded and I know Fiver has had terrible luck with it. I keep it on hand for occasional use with full-tilt .30-30 loads using 170 grain or heavier bullets and a WLR primer.

Definitely a family of ball powders there, and that family has orphans, stepchildren, and a diverse racial history. I figured Bruce Hodgdon bought train car lots of reject powder along with surplus and tested the stuff himself; whatever it came closest to it got put in that can and sold to the public.

 

[hrpenley]

lol, you got me there I have see the same variations you guys talk about, I know its not my measurement, I still weigh every round no matter the caliber, I have learned to leave myself plenty of overhead but I have had good luck downloading those powders, blc2, varget, 4895, 3031 few others may be better choice depending on how far down you want to go or what pressures you want to hang around but I figured he was looking at 335 so I just threw in my 2 cents.
