Any recommendations for a good powder for 10mm? Versatility with other calibers is a bonus, but not a requirement. I currently use Power Pistol for 90% of my pistol reloading with multiple calibers. I'd planned to stick with it for 10mm, but I'm down to my last jug and now that Alliant isn't selling powder I think I need to find something else. I've seen lots of recommendations for Longshot, but it seems unattainable.

The 2 best powders for 10mm are Longshot and Blue Dot for high performance loads. If you want diversity you can't beat Power Pistol.

I only recently got a Glock 20.5 MOS. I bought a pound of Accurate # 5 and loaded some Everglades 180 FMJ. The reloads were in new Starline brass with LPP and functioned 100%.

Does Blue Dot generate a nice fireball like it did for one of my .357 Mag loads many years ago? A big fireball at the range makes 10mm so much more fun! |

I have titegroup and bullseye… are either of those good for 10mm?

Can't speak to Titegroup, but Bullseye is suboptimal for 10mm. Burns too fast, meaning the load range is going to be pretty narrow before you hit unsafe pressures, and you would be on the low end of velocity for it.
I loaded up a hundred rounds of 180gn PCLRN with Bullseye during the pandemic powder drought, when I was trying to make use of whatever I had available. I did not chronograph it at the time, but I recall not being very impressed with it in my 1911, plus I found it to be annoyingly dirty. Win 231 was not all that different, honestly, but it has a slightly broader loading range, and I've found it to be surprisingly consistent in terms of velocity, although you are still stuck the 1100s at safe pressures. I ended up settling on it as the most versatile of the pistol powders I keep on hand, because it is good enough in a pinch for most calibers I load. Like a lot of other folks on here, I prefer Accurate #9. |

Blue Dot is about the best 10mm auto powder you will find. It is a perfect case fill, speed, and provides maximum velocity. To top it all off, it's about the most accurate powder I've ever tried. Unfortunately it too is an alliant powder.
The best thing Hodgdon has right now is Accurate #9. Longshot is good too, but it's about like power pistol. You will get good velocity, but not quite what you can with bluedot or Accurate #9. If you for some reason happen across some old powder, SR 4756 was a top tier 10mm powder. 800x can be very accurate, but it is a little fast for best velocity. I should say I've only ever tried 180, 200, and 220 grain bullets. Maybe the light bullets would be phenomenal with longshot. Between longshot and Accurate #9, I would go with #9. Between longshot and Accurate #7, I would go with longshot. |

What about BE-86, a local shop to me has an 8lb on sale for 210.00. I was under the impression that it was one of the best powders for 10mm and .40S&W. I have been using Longshot and 231 with good results, Tightgroup works well too.

Do as you wish, id just shoot the 45 acp at that point. |

I tried AA9, Blue Dot, Longshot, and 800-X.
AA9 and LS were both very consistent. I'd not hesitate to use either one. Wasn't a huge fan of Blue Dot. It wasn't consistent for me. 800-X is discontinued so moot point. |

My post from a 2021 thread. Not much to update, I still haven't tried the Longshot.
Link to thread:https://www.ar15.com/forums/armory/10mm-Reloading-Questions-Concerns/42-528070/ Posted: 9/9/2021 6:40:46 PM EDT[#2] I like LPP brass. Starline or Hornady. In my G20 with factory internals the results with AA9 are below: Hornady brass WLP primers, March 2015 shot over Shooting Chrony Master at 15 feet. Five shots per string. 13.8gr AA9 Low 1169 High 1178 Avg 1174 fps ES 9.45 SD 3.6 14.0gr AA9 Low 1203 High 1211 Avg 1207 fps ES 8.07 SD 3.31 At 14.4gr AA9 shot over Chrony at 5 feet Low 1228 High 1244 Avg 1236 ES 15.67 SD 7.34 14.6gr AA9 shot at 5 feet with one shot tossed out Low 1224 High 1254 Avg 1240 ES 30.06 SD 14.79 From that testing I compared to factory loaded Hornady Custom 180gr XTP ammo and found that 14.0gr of AA9 pretty much mimics the factory Hornady load. What I load for 10mm 90% of the time is 13.8gr. I have experimented with Silhouette and 800X also. AA9 is best for me unless I want nuclear loads, then it is 800X. I have Longshot also but have not tried it yet. FWIW, my Chrony is iffy. Very hard to get good readings in certain weather, not sure how much I trust it. When it works, it works, seems to be trustworthy. When it doesn't work, load, shot distance, etc. It makes me not trust it. With the G20 when I had to back it up to 5 feet to get consistent readings I start to lose trust in the reading. I would like to do the below test again in good weather at varying distances to see if I get different results. (or put a round through the Shooting Chrony and buy a LabRadar...) In March 2017 shot in my G40 with a 22lb ISMI flat wire recoil spring shot over the same Chrony at 15 feet: 10 shot string, WLP primers Hornady 2X fired brass 13.8gr AA9 Low 1256 High 1301 Avg 1276 ES 44.72 SD 15.23 ETA: all loads above the bullet was seated to 1.255" and crimped with a Lee FCD at just over 1/2 turn from contact. |

Thanks all! It seems like AA #9 is the way to go. Unfortunately everywhere I checked locally was out of stock. I may have to just order some to try. I did find some Longshot, but I didn't pick it up since I'd mostly decided on AA #9.

I can’t remember my load off the top of my head, but I’m getting 1250 fps under a 200gr bullet out of a factory barrel. 1300 fps for a 180gr bullet IIRC. ETA on second thought don’t, I just remembered I’m running a bit low.

I did find some Longshot, but I didn't pick it up since I'd mostly decided on AA #9. It looks like it's in stock online, so do that as you wish. It is the best powder besides Bluedot I am aware of. That said, I wouldn't shy away from Longshot, it's actually a good powder. It's a little fast, but it's still right up there to the point it doesn't matter much. Lot's of guys go over max a little in 10mm to get that speed back anyway. Kingston fisher above apparently shot over max by a 1.1 grains. 200 grain at 1250 fps from a 5" barrel is over max no matter the powder, but many people do it. Hodgdon lists a max of 8.2gr Longshot with a 200 gr bullet and 1172 fps in a 5" barrel, so it's no slouch. It's actually right there with Accurate #9. |

It was always listed for 9mm and 10mm. Alliant must have dumped that data to push be-86 when it came out whatever that was 5-10 years ago. Is this what getting old feels like?

I have tried the following powders in 10mm;
Auto Comp, used with 125 gr frangible bullets bought during a shortage. Meh, and found I didn't like bullets lighter than 180 grs (175 gr HCPC the exception). HS-7, using up a partial pound I had with 180 gr plated. Ok CFE Pistol, 180 gr plated, Ok. Powders I would use if I didn't have my favorites, also used for 3/4 powder range loads; 2400, have lots. I load 175 gr HCPC (home cast powder coated), 180, and 200 gr plated. Not bad at all. Not quite full power. BE-86, lucked into a good amount last Spring, 175 gr HCPC, 180, 200 gr plated. Good fit, but not quite full power. Power Pistol, one of my favorite pistol powders. 175 gr HCPC, 180, and 220 gr plated. Great results, not quite full power. My favorites that I load full power loads with. Full power=180 gr and 1200 fps. Blue Dot, an old favorite of mine. 125 gr frangible, 175 gr HCPC, 180 gr HP's, 180 and 200 gr plated and FMJ. Great choice for full power. AA-9, I'm late to the game here, but really impressed with this powder. Bought when it was $20 and $25 at the funshow. 200 gr plated. Good powder. Long Shot, tried it only because of all the positive comments here. Comments were correct. 180, 200, and 220 gr plated. Good powder. 800X, saved the best for last. Had a 1 pound can I started with, then scored an 8 pounder from a buddy. 175 gr HCPC, 220 gr plated. The full power 220 gr loads=hold on. Shooting a Glock 20 clone, and ported M&P. Many of these powders are suitable for cast PC and the various plated and jacketed I didn't list. My list was of only what I have tried. I have a 200 gr mold I hope to get some bullets out of this summer. |

Quote HistoryOriginally Posted By fgshoot: What? Herco is one of the most popular 9mm powders ever. It was always listed for 9mm and 10mm. Alliant must have dumped that data to push be-86 when it came out whatever that was 5-10 years ago. Is this what getting old feels like? Next thing I hear, someone wont have used Unique because there's no data. Yeah, nothing there now. The 45 Colt loads are pretty stout though. |

My guess is that herco and BE-86 are so similar you probably wouldn't want to try it. The real advantage to herco is the huge amount of data for it over the decades, the stuff is almost 100 years old. If you don't load for shotgun though, then I wouldn't worry about it. |
