THE 10 Powder and Best 180/1300 Load.

Discussion in '10mm Reloading Forum' started by 3/4Flap, Feb 1, 2011.

  1. The way I always do it is to ask, then check.

    Has worked for me since I bought a computer 10 years ago...

    1} What is THE Best powder for 170-180 grain 10mm loads? Meaning best, favorite powder for loads generating 1250-1300 fps with 170-180 grain bullets from a stock G20?

    2} Favorite specific load for 180 grain bullets at about 1300 fps in the selfsame G20.


    The "10 sites" are the best on GT.

    I've heard that 800x Hi-Skor produces some of the best results for 10mm. That's probably what you're gonna get here when others chime in.

    My favorite powder for 180gr bullets is Longshot. If you're looking for a safe 1250-1300fps 180gr load, Longshot & CCI350 primers will get you there. Start at the minimum charge, and work up to 9.5gr (Hodgdon's listed max). You should get what you're looking for at around 9.2gr. I didn't chrono them, but I worked up to 9.5gr with my stock barrel, and had no excessive pressure signs.

    Well, I love 800x, but only for handloads. For reloading, I prefer Longshot -- it's easy to meter, very predictable, and puts up respectable performance at conservative pressures from book loads. E.g. lists 180 grains at 1287 fps; with pressure only at 34.6kpsi.
  5. Thanks very much.

    What is the consensus about Unique and 2400?

    I've seen quite a number of loads listed for 2400 in various places but I'm thinking burnt powder residue might make a mess of the gun in no time. Ditto with old Unique but possibly not the new stuff.

    Unique is good for lower level target/plinking loads, but IMO 2400 is too far down the burn rate chart for 10mm. I experimented with Alliant Steel, which is faster than 2400. I couldn't get it to consistently ignite, even with magnum primers & a heavy crimp.

    Scan through all the Powder stickies at the top. You should find most of your answers there...
  7. Thanks,

    Looking for powders that are available around here, I see AAC #9 looks pretty good in the books and up top.

    Huh, I'll have to get some Longshot and give it a try when I get my press. So far I'm interested in Hi-Skor and Longshot, Blue Dot not so much since I don't care for the flash/noise.

    A9 is by far my favorite 10mm powder for a number of reasons. I haven't had as good results with 800x as have others. A9 is clean, easy to meter and low flash. If you see from some of my other posts, I'm beginning to sound like an Accurate Powder salesman. I'm a big fan. In the past, I've always run with cci mag primers. I'm am reworking some of my A9 loads with standard primers to see how they run.
  10. Vihtavuori N105 and CCI 350 LP Magnum primers. Start at 10.0gr and rise with 0.2gr steps. At 12gr you will reach reasonable safe limits, but if you have unsupported barrel take care of smileys from very start and STOP when they appear. Stay with 1.260 OAL.
    If you will test and shoot N105 rounds in summer, CCI 300 LP would be better (safer) choice.

    More info here:

    I don't guarantee you can make the same safely, so take care of overpressure signs, wear "all arround" kevlar or spectra gloves and best safety glasses e.g. Revision or ESS.
    If you care a lot about your face, motorcycle helmet might be a good choice :supergrin:....ok just kidding
    P.S.: I'm not Vihtavuori salesman, just can't buy any other brand here to load decent 10mm rounds. Well, Rex Magnum is fine too, but this one is not available in US so far.

    I always recommend AA#9 powder FIRST to folks who are just getting into loading warm to hot 10mm ammo. It's pretty forgiving, meters easily, and fills up the case (so no issues with double-charges or powder-position-sensitivity).

    2400's geometry is such that you can't get enough of it into the case to get to the velocities you want. I look at AA#9 as a slightly-slower, more-dense-compacting version of 2400. It will get you what want, but 2400 won't get there. The issue with residue is more from 2400 not being able to get up to sufficient pressure to consume itself properly with 10mm loads.

    There are many other powders which work well. Another favorite for 180s for me is VV N350. It's a little too bulky for getting top velocities with 200gr bullets, but it works well with 180s and especially 170s/165s.

    As far as primers go, I find magnums to be unnecessary in the 10mm. I like the Winchester Lrg. Pistol which is half-way between a magnum and standard primer and works great for large-loads in the 10mm.

    No one is talking about Alliant Power Pistol, is there a problem with it ?. Being a new guy here I'am always look for advise. I started loading 10 mm about two months ago. I load 180 and 200 gr. (Hornady, Remington and Zero bullets) with Power Pistol. Having good results loading 8 grs. I shoot a Glock 20 all stock.

    Several of my manuals list Unique as their most accurate load. I've used it in my 165 grain TMJs and 180 grain TMJs and it is real accurate.
    I also worked up a 155 grain plated load which is amazingly accurate.

    Fast Eduardo...I have used Alliant Power Pistol with Hornady 200Gr XTP's for top performance out of the Glock 29. It burns better than Blue Dot from the 3.78" barrel and gets better velocity.

    Power Pistol 10mm Load info tested July 6th 2008

    Hornady 200 grain XTP COAL 1.26”
    8.0grains Winchester cases
    300 CCI primers
    1170-1200 fps velocity S&W 1006 5”
    1080-1130 fps velocity Glock 29 3.78”
  15. Thank you all.

    Very interesting and helpful.

    I'm going to look for AA9 but since I have a bunch of Unique, I'm curious...

    With lighter bullets, as in 155-175, what are you guys getting for velocities?

    I'm leaning on getting a 6" KKM barrel, but haven't quite settled on a bullet weight yet. For my goals, wolves and deer and 200 pound bear are the biggest critters a bullet from my gun is likely to run into.

    Nothing wrong with Power Pistol, but it's a little faster than the powders that generally get top performance. If you're satisfied with 85-95% performance level (and there's no reason NOT to be), Power Pistol works great, as do a bunch of other medium-slow pistol/shotgun powders such as: HS-6, Herco, Win Action Pistol (can still be gotten from Ramshot - called Silohuette), AA#7, and WSF.

    For absolute top-end loads, you need to move up to: 3N37, 800x, Longshot, HS-7, AA#9, and 3N38.

    One of the first wildcats that started the 10mm journey was the 40 G&A, and they used Unique for loading it. It's a good powder, but like I mentioned to the other poster above, it won't get you max performance. Nothing wrong with that, I don't load to that level most of the time anyway...
  17. Even if Longshot is not available it's worth the wait or trouble to get it. Top velocity with minimal pressure and as clean burning with minimal flash as is possible. In 10mm 9.4 grains is running 1325fps with 180 grain XTP's. I bought 16 pounds and now use it in 9mm, 357Sig, 40S&W, 10mm, 357 and 44 mag. It is my "go to" pistol powder.

    I would probably look at the 200gr. XTP's if I wanted hollow points to carry in the woods... but honestly, I would probably rather carry a nice strong hard cast bullet in the 200gr. range for maximum penetration.

    Still a 200gr. XTP will probably do an excellent job if you drive it at 1200fps or so. You could go even higher than that with the right powder and since you're getting a 6" KKM AM barrel, you could easily pull it off..

    I prefer Longshot myself. For one I have a lot of it, and my go-to load for 180gr 10mm loads is 9.5grs, the listed book max. I've used that load for both FMJ/JHP and hardcast.
