Home Forums Reloading Big Game Rifles Tell me how good h335 is......

Gunshop didn't have the powder I was looking for but a pound of this called out my name and I took it home the other day.
Looks like it could be real good for the lighter bullets in 3030 and 308 which I have both of. Maybe good in 4570.
What else have you had luck using it for....I have many calibers from 243-4570.
Thanks for input so I can play properly and get this powder to work.

Kraky,

not to be the party pooper....

H 335, is the only powder I have had blow up an action ( although it was repairable) utilizing load manual specs...

it was with a 223, and real bread and butter load, of 25 grains with a 55 grain SP...

and it happened twice!!! no less, one Black Hills load and the other one of my handloads...

I admit, I don't trust it in a 223.. and the couple pounds I have of it, I use sparingly...

it was accurate, but the other down side of it, don't use it for night varmint shooting or shooting prone on top of a dry grass area... or if you do, enjoy the pyro technics of it.....

real "flashy" powder...

Very dirty stuff. You will curse as you attempt to clean your barrel.

Oooh...not off to a good start here LOL.
I "read on the internet" that early 335 was some sort of slow burning pull down powder but newer lots in the plastic cans are quite a bit faster. Hogdon still lists it as slower the 748 on there burn chart but their online data shows it much faster. I also read somewhere it was dirty....I should "read" before I buy I guess!
Someone can give me a positive here.....please!

It meters well.

Ive only got half a pound left......

H335 is very temp sensitive. When its hot outside so is the powder.

The original H335 was a mil-surp powder. They ran out in the early 1990's and switched to a newly manufactured version, which was considerably faster.

A lot of .223 shooters have burned a lot of H335, because for quite a while it was one of the better ball powders available for the job. It metered well from a powder measure and usually shot quite accurately.

But the downsides have all been listed above: pretty temperature sensitive, especially in heat, and very dirty burning. It would carbon up a .223 bore so quickly that after 50 rounds you'd get the impression from looking at the muzzle the bore wasn't copper fouling. It was--but you couldn't see it due to the carbon! H335 was one of the main reasons pratrie dog shooters scrubbed out their bores in the field every 50 rounds or so!

All that said, if you're using H335 for deer hunting the powder fouling won't be a major problem. The temperature sensitivity might be, depending on the range of temps you typically hunt in.

It shoots great but is dirty and as said gets hot in the summer. For me I like Tac and AR COMP better. As of lately I switched to Varget for .308/.223.

Be careful! I had one lot of H-335 that with the listed starting load would almost give me top load velocity in a .308. I use a lot of it and don't notice it to be any more dirty burning than BLc-2, H-414,or H-380. On another note, I will probably never buy another kernel of it as I have plenty.

I burn a lot of H-335 in my AR's, but the loads were worked up during the summer and are burnt during the summer.

Since I'm not shooting prairie dogs or benchrest, I've never noticed any fall off of accuracy from fouling. I clean them every 200-300 rounds whether they need cleaning or not.

I used it in my son's 30-06 to duplicate 300 Savage velocities. Pretty impressive fire balls each time the trigger was pulled.

I also used it in his 223 but I've emptied my supply and won't be buying it again.

I like H335. It gives me better groups in my 222 and 22-250 than H4895. It does throw some fire out though. It's a very versatile powder IMO. I haven't noticed it being dirty but I clean my guns very often.

It's been my go to powder for 223 pdog guns. I've not had any problems with excessive carbon fouling but rarely shoot more than a 100-200 rounds between cleaning. The carbon fouling from H335 seems to clean as easily as any other powder IMO. Very accurate powder in 223.

I love H335. Meters well, and is accurate. I have not been able to find any for over a year.

works in 222 with the 45 grain tsx

H335 is my go to powder for my Marlin 35 Rem. Lever gun loves this stuff. Haven't tried it in any other caliber.

335 is a good powder , but I won't buy any due to the fact Benchmark is MO better. All the best of 335 without the downside.

Strap,

If you didn't use H335, you wouldn't have to clean your guns very often.

Agreed.

Besides Benchmark, there are a bunch of powders out there now with similar burn rates, that don't have the downsides of H335.

Exactly.

But many handloaders often keep using what's worked for them for many years, either because they never try anything else or they bought a lot of it.

Once in a while one of these guys actually tries something different and sees the difference. I have a couple of friends who claimed for years that XYZ cheap bullets were just as accurate, explosive and flat-shooting on prairie dogs as those more expensive plastic-tips. Then both of them tried some of the plastic tips, and changed their minds. As soon as I tried Benchmark and Ramshot TAC in the .223 my remaining H335 went unused. And nowadays there are even more clean-burning suitable powders.

I was running 25.0 with 75's in my 223AI with so so results. Switched to 80's and Varget and don't think I'll be going back....

I'd love to try other powders. Unfortunately, I've never seen a can of CFE223 and it looks like it's going to be a long time before I will. Luckily, I still have the biggest part of 8lbs. of H335 left. At 25gr per load, it'll still take a year or two to use up.

Yep, a max charge touched off with a magnum primer pushing a 200grn Core-Lokt, accurate, minimal muzzle flash (24" barrel)and I haven't noticed it to be any dirtier than any other powder?

Don't rule out H335 for the Big Bores either. Check Hornady and Barnes for the .458 Win Mag and .45-70 with the heavies. I've found nothing better in those two. And I'm not alone in that discovery -- when you need more room for powder. As well, I've found temp stability to be awesome... one of the best for .458 caliber. It might be a different story for the small bores, I acknowledge, having never used it in anything but .358 and .458 bores.

And, in the Big Bores there's little cleaning to do anyway as you'll rarely fire enough to dirty the barrels. The exception is all copper fouling.

Have always heard that 335 metered great. Do TAC and Benchmark behave just as well in the powder thrower? For the record I just bought a pound of Benchmark but it was an easy choice, only 223 suitable powder I could find local.

I started shooting Pdogs with tac. Shot good and all that stuff. The next year, I could not find any so I checked the burn charts and here is H335. Tried it and got the EXACT same speed with the EXACT same powder charge of tac. ??? Dirty ?? Wife shoots 100 to 150 rounds a day and we clean every night so I guess I never noticed it being dirty. Maybe 5 patches of CR10 and clean as a whistle. Never did any Pdog shooting in the dark so I missed the flash.. Is there better powder ?? Maybe... but 5000 dead prairie dogs haven't complained yet....

Yes they do, Benchmark is just an extreme version of 335

Thanks, didnt realize that

And cleaner-burning as well.

I was under the impression that H335 is effectively W748? Not so? Certainly works just like it in my 223AI.

748 is a lot slower than 335. It would be more in line with varget and BLC 2.

Looks like i can use it pretty easy in my 30-30s, 308, 35rem, and 4570!

I love h335. Great for my 223 444 and 45-70

444 300 sierra


444 300 bearthooth bullets




45-70




223 50 gr bt 5 shots

I like H335 and have for around 30 years. I originally used it in a 223; still do. It's also useful in several other cartridges. Yes, it does flash in some applications. Dirty? That's largely overplayed unless you're running many dozens or hundreds of rounds in short time intervals perhaps. It isn't like it creates a horrible mess that requires hours of cleaning.

Fotis...mind sharing that 4570 load?

350 gr Hornady Sp 58gr H335

Thanks...somewhere around 2000 fps?

I used to use a lot of H-335 in .223. I noticed the temperature sensitivity on a prairie dog shoot in AZ. I switched to H-322 which seemed to work just as well but was much more stable. I have now switched to TAC, but X-Terminator was also very good with 40 gr bullets in the .223. Tac is more versatile, so I've made the switch. TAC measures just as well as H-335 without the downsides. I also switched to Big Game in my .22-250 loads for the metering accuracy and it shoots superbly.

yup 2000-2100 pending on barrel

Has hogdon changed the powder formula since the 90's? I have 2 cans i bought never used.Seems fine. Thinking of using in place of tac in a 350 rem mag.

They never made 335. In fact Hodgdon has never made any powder. They started by selling military surplus powder, and nowadays have their various powders produced by different companies.

The original powder was a pile of mil-surp stuff that was sorted according to burn rate. Some of it was BL-C, some of it was BL-C2 (Lot 2), and some was H335. There were probably other powders sorted from the same batch.

When the mil-surp stuff ran out in the early 1990's, Hodgdon contracted to have a similar powder produced. I acquired some of the new stuff but didn't know there was a difference. Had to reduce my long-standing .223 loads 2 grains.

If I remember correctly i bought it during the component scare,shortage in the 90's and never used it.

In my 222 out of a 24 inch barrel

Remington cases
cci br4
25.5 grains h335

45 grain tsx 3350-3360 at 65 degrees

Shoots .5-.7 pending temperature and how much coffee and sleep my workaholic self has.

I did work up to this load very slowly looking at some of the older manuals including an old speer and the newest nosler manual. It seems way off the chart however the newest nosler says that 25 grains is okay with a 50.

The good thing is that it shoots about an inch and a half almost directly below my reloads with reloader 7 and the 40 grain v max.

Woodchucks to deer with one rifle.

I'm most of my way through an 8# keg. Is it the best powder for every application, no. Have better powders been made since, yes. I'm not in a local where temperature sensitivity is an issue

I have primarily used it in the .223 and 5.56. I've also used it in the .243 with 58 gr bullets and in the .308 with 110-125 gr bullets. Accuracy in the .223 has been excellent. Accuracy in the .243 and .308 hasn't been so great when I did load work so I don't use it in those rounds. Muzzle blast from the .243 and .308 have been most impressive.

A pound of H-335 will serve you better than an empty shelf of a better powder.
