NOT a RELOADING expert, but I have had excellent results with H-335 in my 7.62 x 39 SKS loads. Always start at the lowest recommended powder load and work up. Also I’ve have had good results with Alliance 2400 powder. H110, I do have a couple of pounds someone gave me but haven’t had the time to sit down and reload anything with it, but start low and work up.

Be careful with H110, Hodgdon warns not to load "below" starting grain reccommendations. Its a funny powder that way. This powder needs higher load density to perform as expected.
I have found H335 has worked great for me when loading 150 grain .308 diameter bullets in my Ruger Hawkeye compact 7.62x39.
(2050fps.). I use Hornady or Sierra flat based 150 grain spire points.

Red Dawg, I can relate with prosper and the Reloader 7. I have tried the IMR 4198 and IMR 4895, but they didn't seem to perform that well.
Another CGN member had posted results with the Rl 7, so that inspired me to try it also. I have a Lee Enfield that I rechambered to 7.62x39, which would be sort of simular to your A1A, and the results were outstanding.
A four shot 1 inch group at 100 yards. The only reason it was that big, was because I pulled one shot. Three shots were touching each other.
My recipe is, Lapua brass, CCI large rifle primers, 123 gr. Hornaday V-Max bullets and 24.5 grs. of Reloader 7 powder.

I suppose it depends what you're looking for. In an SKS or mini, you probably won't be able to detect much difference as the guns just aren't that accurate to begin with. 322 worked OK, as did WC-735 surplus. 4227 wasn't great, and I never tried 2400 or 110 as I think they're probably too fast-burning for optimal performance. AA-1680 is probably a good candidate to try, but I never did. RL-7 gives me the most velocity with the best accuracy of any powder I've tried, and with my bolt-gun, gives TRULY exceptional accuracy. It cycled my SKS just fine
Ok - wasn't sure with H110.
Will try RL-7 - I want velocity, but don't want to play around with pressure issues, but also have some decent groupings - preferable under 2" at 100. If anyone has played with H110 - Let me know - apparently it's a slow burning pistol powder, best ignited with magnum primers as well.

On that note, anyone have load data with H335 and RL-7 they'd like to share?
Just loaded 110gr V-Max and 125 Gr TNT HP with 30 gr of H335 behind them, while loading same bullets again with 26gr RL-7 behind 'em.
These aren't max, but getting up there. Would like to see if anyone has similar loads with AIA 7.62x39 and had success with 'em? Hunting season is around the corner, and unfortunately range-time is next to none cause I'm too busy ;D

Loading .44 mag with H110 the accuracy is poor when there is room in the case for the powder to shake. When the bullet compresses the powder so it can't move around I get a lot better accuracy. Gun is a Marlin 1894 lever.
In my .410 shotshell loads using H110 powder it's always compressed and works well.
Just my $0.02 on my limited experience with H110 powder.

Agreed.
H110 definitely likes to be compressed.
When experimenting with it in my .454 Puma, H110 compressed with cream of wheat gave me more velocity and about a 75% reduction in shot-to-shot velocity variations.

H110,, only pack 10 rds, with 17gr of H110 @ 123gr berries bullet,, did not cycle, fired ok, but stove piped ever second round,, may try 17.5 or just find something else to load with this powder.
Update for those who care ;-)
Hi All.
Bit of an update -
So here it is:
I tried pushing a 110 and 125 gr .308 bullets.
My findings were that R7 worked better and got velocity around 2400 or standard pressures from surplus - best with the 125 gr bullet - approx 3-4" group at 100m - which is junk in my opinion, especially when aimed shots have to count. Solid snap and "crack" when trigger is pulled.
H335 worked better with the 110 gr and with a fairly tight group, however velocity was probably closer to 2000 with the shell just about maxed out - plus some grains left over and sound of shot went "fap".
SO, currently loaded casings with both 19 and 20 gr of H110 with 110gr VMAX, which I believe is 2 gr below suggested loads for 90 gr bullets (of which had velocities of approx 2700-2800 fps with about 22 gr of H110 - Reload data from Lee die set).
The casing is only filled to about half with 19-20 gr of H110 - so lots of room for upping amounts, however still sketched on reports of guns going kaboom from lack of powder/spike in pressures. People also using this powder for supersonic loads in 300's with relatively light bullets.
So we will see! Any input would be great! Thanks!

Kabooms in rifle cartridges generally happen for two reasons when it comes to using reduced loads,either double charges with fast to med fast burning shotgun/pistol powders or going below listed load data. The term for it is know as SEE Secondary Explosive Effect,SEE can destroy the strongest rifle action and it can happen on the first shot or the tenth. SEE is the result of slow or incomplete ignition of small amounts of smokeless powder. The powder smolders and releases explosive gases which, when finally ignited, detonate in a high order explosion. The warning sign for imminent SEE is a hangfire or delayed ignition. There is no warning sign for a double charge of fast to med. fast burning powder if you go over the specified load it just simply blows up
As long as you stick with the Min. and Max. load data listed for a given bullet,powder,primer.cartridge case combination you should be fine. I only know of one load using H110 found here http://archives.gunsandammo.com/content/the-762x39?page=1
For commercial jacketed bullets I only shoot two weights Hornady 123 gr. .310 dia. FMJ,V-MAX and SP or Speer,Sierra or Prvi Partizan 150 gr. .311 dia. bullets. My powder of choice is Reloader #7 mainly because it works with so many different weight bullets is readily available,gives excellent accuracy and is cheaper than AA-1680 or IMR-4198 around here,both are good powders as well and will give you excellent bang for the buck as well as accuracy and velocity.
For reduced loads one of which is my 170 gr. gas check cast lead bullets I use Alliant 2400 the good thing about 2400 is that it's neither case capacity or position sensitive and ignites readily when used at the recommended starting load of 11.0 grs. in the X39 case with a Max. load of 15.0 grs. In my Chinese SKS 12.5 grs. gives me 1450 fps. and dumps the brass right at my feet. 14.5 grs. give me 1950 fps. average MV but throws the brass about 15' away. Both loads shoot under and inch at 50 yds. with the irons.
For sub-sonic loads I cast the Lee .314 90 gr. SWC if you don't cast Hornady makes the same commercial swaged lead bullet. You can push that little bullet with 2.7 to 3.0 grs. bullseye it not a Max load but above 3.0 grs. and you start to get leading with PB bullets and accuracy goes south. MV will runs somewhere between 850 and 950 fps. and it's a excellent plinker small game load.

I'm glad to hear that Reloder 7 is giving good results.
Does it cover the spectrum of bullets from surplus through 150gr and up to 180gr?
I know I must have asked this before in another thread a long time ago, but has anyone tried H4198?
I bought two pounds of it to play with that I haven't even opened yet. I was thinking it might be less temperature insensitive than other powders.
