I just go a pound of H110 to reload for my Python, King Cobra, and Anaconda. But before I fire any reloaded rounds through any of them I'd like to know if anyone has experience any negitive issues with thier revolvers after firing reloads loaded with H110. With the way these revolvers have sky-rocketed I would hate to damage them in any way. The King Cobra and Anaconda are very special to me as I was the first one (other thab Colt) to fire these revlovers and plan on passing them on to my son and daughter.

Thanks

Tony

I have been using it for years. Plinking loads I go to W231 or Universal Clays with about 8-9 grs for a 240 gr cast.
Heed the warning on the label concerning reduced loads, give it a fairly heavy roll crimp.

I use it in my Ruger SBH. I don't know if I would feed those revolvers a steady diet of it. Especially the Ananconda

WHAT KIND OF NEGATIVE ISSUES ?

The loading manuals are FULL of pressure tested data for H110/296 in both of the cartridges you mention. There is NO reason for you to have so much as a single problem if--IF!!!---you follow that loading data.
NOW....if you think you'll just take whatever loading data you can find off the internet all bets are off and you'll be looking for trouble.

I use it as well for my S&W 686-4 and 629-4. H110 loads should not be reduced below the minimum and need magnum primers. They make for full power loads, and undoubtedly result in more wear than plinking loads of Unique or other powders, but they are among the hottest loads and are fun to shoot.

There was a minor kerfuffle over it and L'il Gun used in Freedom Arms revolvers, specifically the 454 level loads. There was concern over throat erosion and forcing cone failure due to perceived higher burn temps. I emailed Hodgdon about it and was provided burn temp data for a number of Hodgdon and Winchester powders. All were in the same class and burn temp range. Mostly the only caution with H-110 is to not load it below the published data, it isn't safe at low pressures; that's paraphrasing the obligatory safety bulletin, good shooting.

H 110 is the favored powder for both .41 Magnum and .44 Magnum loading here, used in full-power applications in Smith & Wesson Models 29 and 57. It also works well in .357 Magnum but I believe that 2400 is just a little bit better.

Thanks for the replies all. I plan on starting out at the minimum and woork up from there using data from the Hodgdon website. Will probably look for another suitable powder for lighter/plinking loads, as I want the kids to have a chance to enjoy my revolvers.

Yes, you will need another powder for lighter loads. I am guessing your guns have at least a 6" barrel? From my experience, it is one of the top powders for straight cartridges magnum handgun loads with at least a 6 in. barrel. The last Lyman handloader book showed it edged out 2400 by about 100 FPS.

Here's an exerpt from some information I posted about the .44 Magnum years ago. I had set out to work up to maximum loads with the powders below to see what sort of velocities could be "gin'd" up.


240 Grain Sierra JHC, Max/H110: MV 1542 ME 1267 ES 25
" ", Max less 1.7 grains/H110: MV 1478 ME 1168 ES 38
" ", Max/W296: MV 1510 ME 1215 ES 49
" ", Max/Blue Dot: MV 1461 ME 1135 ES 28
" ", Max/AL8: MV 1430 ME 1090 ES 30
" ", Max/2400: MV 1419 ME 1075 ES 71
" ", Max/Unique MV 1246 ME 841 ES 32
" ", Max/IMR4227 MV 1238 ME 817 ES 18

180 grain Sierra JHC, Max/H110: MV 1814 ME 1316 ES 62
" ", Max less 2.3 grains/H110 MV 1757 ME 1049 ES 40
" ", Max/W296 MV 1766 ME 1247 ES 49
" ", Max/BlueDot MV 1762 ME 1241 ES 33
" ", Max/AL8 MV 1694 ME 1147 ES 54
" ", Max/2400 MV 1620 ME 1049 ES 81
" ", Max/Unique MV 1548 ME 946 ES 37

All loads fired over a Oehler Model 12 chronograph from a Smith & Wesson Model 29 with 8 3/8-inch barrel
*Max means the maximum listed load as published in the 1978 edition of the Sierra Loading Manual
All loads used Remington cases and Remington 2 1/2 primers

I think H110/W296 is a little more versatile in the .44magnum. I use it for .30 Carbine, .357 Magnum and .44 Magnum. I can tell you that unless you get closer to the maximum published loads for the .357 and use a heavy crimp, you will end up with a bunch of un burned powder all over the place. It also does not work well in shorter barrels even with a near maximum load and a heavy crimp.

Due to the excessive fireball with H110/W296 in .357 I stick with the 158gr bullets. Next time I might even try out some 180's.

Good Luck!

296 is my powder of choice for my 357 magnum rifle. I've worked up a load with Hornady FTX bullets that I like, although have also shot it out of this gun with 125gr and 140gr FTXs, as well as hard cast 158gr SWCs.

It also shoots well with a 125gr XTP and 158gr out of all of my revolvers. A max load with a 125gr bullet is a good "range clearing" load especially out of a 4" or shorter barrel-the fireball and report is impressive! In general, though, for revolvers(like others in this thread) I prefer 2400. Supposedly, ball powders like 296 are worse about flame cutting and forcing cone erosion than are flake powders, although I don't know how true that is.

My only 44 magnum is a 629 "Mountain Gun", and I haven't been brave enough yet to try any 296 loads for it. 2400 does as much as I've felt the need to do, and honestly I use more Unique than anything for 44 mag.

Another powder worth looking at is Alliant Power Pro 300MP, which is a ball powder(or technically a spherical powder, since only Winchester makes "ball" powders). It is very similar in burn rate to H110/W296, and from what I've seen tends to be a bit less expensive. The biggest disadvantage is the lack of load data out there for it. I've found 18gr under a 158gr SWC in 357 magnum gives me 1500 fps out of an 8 3/8" model 27, which is similar to the original "full power" 357 magnum loads.
