IMR 800 x hi skor

[horsemen61]

What is IMR 800 x high skor good for as I recently got a Pound of it for a good price I am just getting into 10mm and I heard it will work in that any other thoughts on this powder guys

 

[Jesse Heywood]

I like it. Have used it in 38/357, 9mm and 45 Colt. Biggest issue is metering. 800-X meters best in RCBS Uniflow.

 

[Hamish]

I use it for .38 Special only. It fills the case nicely so I don't have to worry about double charging.

I have tried it in 9mm, and didn't like it. There was too much unburned powder dusting the bench, and it was messy to shoot. For .38 Special it works well.

I bought a pound specifically to try with 10mm.

I just loaded 50 rounds this afternoon. 9.0 grains with a 165 Ranier flat-nose plated bullet at 1.26. Burns clean, but will throw sparks sometimes (always wear glasses). Slow to meter but is supposed to be the best for 10 mm hunting loads. Also will work in a .44 mag.

 

[kerreckt]

800X, AA7,AA9 and Blue Dot are my favorites for 10mm. 800X gives best velocity. YMMV

800X may bridge in the powder measure. Look in the case before seating a bullet.

 

[gunlaw]

Works great in 45 colt.

Makes a heck of a good 357 SIG load too!! I meter it in a RCBS Uniflow a little low and trickle up with the trickler...

 

[Stumper]

It will make usable loads in just about any handgun cartridge. It is arguably the "best" 10mm auto powder and will run right up with 2400 and 296 in the magnum revolver cartridges. It is a coarse powder so doesn't meter to suit some folks. In the bigger cartridges the slight variations in dropped charges don't cause a big issue(at least with my measures/methods) IMO 800X shines in medium loads in the magnums Full loads in the 10mm and, while it will work in a .380 , 9mm or .38spl and a host of others there are easier to meter/cheaper to use powders for those applications. BTW it was designed for heavy loads in the 12 gauge shotgun.

I use it for 180g 40 S&W. My L-n-L meters it just fine. It does look like black corn flakes though, lol.

 

[abq87120]

I had a problem with set back with my 357 Sigs. Now I use 13.0g AA #9 and 124g JHP from Precision Delta without problems. This is a compressed load. I finish them off with a Lee FCD too. That seems to help.

 

[gamestalker]

I used a lot of it for 9mm & 38 spcl. back in the 80's, and it worked quite well. But I think it might have been redeveloped since then, not sure? Not much else I can add to that.

800x

I use it for OO buckshot loads in 12 gauge hulls.

My favorite .357 load is 7.5 grains of 800x behind a 158 grain lrn or lswc. It is a nice, accurate load that runs about 1200fps out of my revolver and 1400fps out of my 16" rossie.

 

[Potatohead]

It's supposed to be the cats meow for 10mm I do believe. Ive used it in 9mm, though I don't think it's optimal.
Dont quote me but I think my Lee 380 dies have a recipe for it in the instructions, for 380 of course.

 

[NuJudge]

.45 acp and 200gr SWC

There was a Handloader article some years ago where splendid accuracy and excellent velocity were the result of combining 800X and 200gr SWC bullets. I tried it, and the accuracy and speed were there, but also considerable blast, and as noted above it meters worse than any other powder on the planet.

 

[yamahawarrior89]

Man that stuff meters like corn flakes, but it is by far my favorite powder in 45 colt once you push it. Light loads are super dirty, but it is quite nice and accurate when it is pushed

 

[TonyT]

HS-800X has some impressive ballistics but it is absolutely the worst metering powder I have ever used. Years ago I purchased a keg for loading 28 ga shotsheel without heeding the store owners advice that it meters poorly. First ever shotgun squib loads. It took me a long time to use up that keg.

 

[bluetopper]

If you can put up with the dime size flakes its performance is great in 357 and 44, and 45 Colt

 

[KansasSasquatch]

I worked up a load for it with 230gr plated RN in .45acp. It worked well but had more muzzle flash than I like. I never used much of it because of how it meters. Since then I've started using it to fire form 8x57 brass converted from .30-06. I used a filed down .40s&w case to make a dipper that yields between 9.8 and 10.2gr, that's better than I've ever got it to meter out of my Hornady powder measures. Cornflakes.....more like Buffalo Chips.

 

[CoalTrain49]

We used to use it for heavy 12 ga. trap loads. Makes a pretty nice 1 1/4 oz load for Annie Oakley shoots.

You asked.

 

[Peter M. Eick]

Works great in the 10 especially with lead bullets. I picked up 8 lbs of it a few months back just for 10mm.

Imr 800x

Works excellent in 44 magnum one of my go to powders for the 240gr LSWC.
