    165gr Sierra JHP @ 1.260"
    9.8gr Power Pistol w/ CCI LP
    Stock G20sf

    Average: 1,311 fps/ 630 ft-lbs

    Brass looked great (was using 1x Remington Nickle) and feel the book max of 10grs is perfectly safe. I'm really liking Power Pistol more and more. 10gr is shown to get 1314 fps and I'm right there with 9.8gr. So far with 10mm, Power Pistol has been very, very close to giving me what they said it will, and I like that.

    I tested some Longshot with the same setup as above today also and while it's velocity averaged higher, PP was a little more consistent. I'm sure it could be driven faster, but in the stock setup, I think 1300+ is plenty fast for a 165gr.

    Thanks for the report. I find the Power Pistol provides better velocity than other powders (Blue Dot LongShot) in the shorter barreled pistols like G-29...

    Good to see someone else using MG 180's (JHP, CMJ, etc.) I can't find a better bullet for the price. I just got a case of 155g JHP this week to try out this week. Anyone know how well those MG JHP's (155g, 180g's) expand? Wondering if they'd b good for hunting or SD/CCW. I don't have a range to do my own testing. I can't test on prisoner's in this country.
    Also, 7.3g Power Pistol in .40 w/ CCI SPP in my G23 stock..or KKM for that matter, is a great balance of power and accuracy. They'll take down plates even on an edge hit. I haven't tried PP in 10mm G20FS yet. Any pet accurate loads you might suggest for 10mm using BD, PP, AA#7, AA#5, Silohouette or W231? I'm just starting to reload 10mm for the first time this week. But I've loaded .40's all year.

    Anyone load 10mm rounds in .40 S&W cases? Thoughts? I'd like to shoot .40's in my G20FS for relatively cheap plinking and practice. I shot some of my hotter .40 reloads (MG 180 JHP 1.125" COAL @ 1100 fps avg on chrono) in my G20 and they seems just fine.

    TIA for replies!

    The Montana Gold JHP's expand OK in the 10mm, but shed their jackets quickly.

    Yes, I load 10mm rounds in 40 S&W cases. As long as you're long-loading to 10mm OAL (say, 1.240-1.260" or so), just use 10mm load data. You'll probably find that pressure and velocity are slightly lower than the same loads in 10mm brass.

    Shooting 40 S&W in the 10mm barrel also works fine, in the Glocks. Not advisable in other guns.

    I've only "jug tested" the expansion of the MG 180gr JHP and Yondering is right. I only tired it in the .40, using a max load of Power Pistol and it expanded okay (about .63 ") but nothing to get excited about and the jacket came off and separated into five pieces. I would expect slightly better expansion at full 10mm velocities but don't expect the jacket to stay on the bullet.

    I've had good results from Power Pistol in the G20sf. TiteGroup does pretty well as does Unique, but in all honesty they all shoot very well. As a side note, if you ever load up plated bullets, remember to not over crimp them as it can cause key holing. I loaded up some with Longshot (180gr and 200gr plated) one time and it didn't shoot groups, it shot patterns...and pretty rough patterns at that. I learned my lesson on that one.

    I've not really paid much attention to AA9 and AA5 accuracy wise, but would assume it's pretty good as the numbers are fairly consistent. However I've never got anywhere near the advertised velocity AA9 or AA5 claims for the 10mm...even out of the 6" KKM bbl (AA says they use 5" bbl). For example AA5 claims almost 1200 with a 180gr but I didn't even break 1100 fps from the G20sf. With AA9 I was getting slower than advertised speed with the 6" kkm bbl as well. Longshot does pretty good in getting advertised velocity, not quite as close as some of the Alliant powders, but good nonetheless.

    Since I know the .40 has no problem breaking 1100 fps with a 180gr bullet, I just stick to it for that velocity range. If I want a little faster, I load up the 10mm. Having .40's and the 10mm, I don't see a point in loading the 10mm real light personally, but I could understand if one didn't have a .40 to load for.

    That's one thing I like about the .40/10mm, if you load for both you have pretty much everything covered. You can load light .40's for game use or whatever, normal/mid range .40's for duplicating factory loads. Warm .40's pretty much duplicate mid-level 10mm loads and visa versa, then the 10mm can scoot them on out a bit faster still if you get the itch for extra speed.

    From what I've read on Alliant's site, Promo is the same by weight, but not by volume to Red Dot, thus the charge weight remains the same, but the volume is different. So, you need to reset the volume on whatever type of adjustable volume based powder measure that you might be using. If you are one of those folks who actually measures the weight for each and every charge, you can continue to use the same method that you have been using, but you might notice a difference in the level of the power in the brass afterward.

    I might pick up some Pro Reach if I can find any in town.. Give it a try with 180gr bullets and Starline brass, again with what I can find..
    I wonder where a good place to start is..?
    I see Alliants shotshell data Pro Reach is about 10grs behind Blue Dot, with equal loads, for more velocity than BD loads.. Haven't seen PR on any powder burn charts yet..
    But this powder looks like a high energy powder and sure sounds like interesting candidate for research with 10mm..

    The Pro Reach burn rate (ONLY) falls between Blue Dot and Longshot. Powder densities though, are very different, requiring varying case volume capacities. You can't get enough Pro Reach into a 10mm case to be practical with any bullet weight. It's a (high energy/magnum/long distant) shotgun powder, and should be limited to that. Some shotgun powders work well in some handgun and rifle loads, but NOT all. For example, Blue Dot is a "Magnum Shotshell" powder, as it was originally formulated and intended, and was labeled as such. Now, it's labeled "Magnum Shotshell & Handgun Powder". Other modern powders are labeled similarly, and some that were labeled like this aren't now.

    I've been reloading with AA#9 for my Hornady XTP 180 grain bullets using new Starline brass and CCI300 primers. What I would like is to get some suggestions for using the same components but with Power Pistol. I don't need nuclear loads, I just want to develop a nice, powerful self defense load for my stock G20. Any help would be appreciated.

    Alliant shows the following with 180 grain JHP bullets from 5.5" barrel COAL 1.250"

    Power Pistol 8.7 grains @ 1,240 fps 34,900 psi

    You could start lower than this 8.0 grains will probably be about 1180 fps for your setup.

    Where did you find that Alliant info? I can't find it anywhere, not even on their website.

    Chuck11976, I collect the data over many years of handloading (33+), if you wish I'll email you a PDF from the data I posted. But that is all they show for the 10mm using a 180 grain JHP bullet. I have tested this data from my guns, Power Pistol is a little faster than Blue Dot and using a little less makes it more ecconomical.

    You can't collect enough data resourse materials to make decisions.

    There is a group shot with Power Pistol here at the end;

    9.0grs behind an XTP was one the most accurate loads shot through this factory G20-SF.
    But.. I only found this load after carefully working up from 8.4grs in 0.2grn increments, and paying close attention to case head measurements.

    Alpha Master Chrony {I have to check batteries to see if they are at least 7.5 volt}
    10ft. from Chrony shooting distance
    Glock G20 / KKM Precision 6" drop-in / 17 bs. tungsten guide rod /spring

    Load test:

    PowerPistol 8.7 grain
    WLP Primer
    Starline Nickel plated *new* .960 case length /fresh out of the box
    1.260 C.O.A.L
    crimp .422
    Hornady XTP 180 grain
    6 shot average 1348 fps.

    I question the accuracy of the Chrony due to cold and possible low 9 volt battery. The cases landed 4 o'clock 12 ft away. Controllable recoil and seemed accurate. Shot 60 yrds. @ 16" round gong target 5 out of six hit, my bad on 1st shot looked away for ejected case.

    The velocities seem close, but you may have just been standing a couple feet too close to your chrony and the blast beat the bullet to the chrony.

    That sounds like a very nice load there g29guy. Thanks for posting that. I imagine that the powder burn was pretty clean?
