Thank you, Willy. I think I'll probably start out at 7.7grs using that same 1.26" for the OAL and work it up from there. Did you have any feeding issues with 1.26"?It has been a while since I loaded any, but 8gr of PP under a 230gr FMJ at 1.260" OAL would yield right at 900fps, from my G21, a good service round simulator, notwithstanding the wow finish (lots of flash).
No, I never have feeding issues with my trusty G21. I even had some plated SWC's that I had miserable luck with every other 45 Auto gun I own. I finally shot them up with my G21. She is ugly, but that gun just runs and runs.Thank you, Willy. I think I'll probably start out at 7.7grs using that same 1.26" for the OAL and work it up from there.

I'll be happy to give you what I have;What are you folks using for 230gr FMJs? For years I have used Unique and 231 for my 45s. I acquired some Power Pistol recently, but haven't used it yet. I researched it a good bit, but Power Pistol data is all over the road for the 45 Auto with pretty significant load for load variances in COL.
For those of you with completely stock Glock 21s, what are you using for charge weights? COL?
I want something to consistently give me 875-900fps. The Hornady and Speer manuals are as different as day and night, and much of what I have read in other forums about Power Pistol is just as confusing.
Thanks in advance.
I got back into reloading a year or so ago. PP was the only powder I could find. I'd used BE and Unique before.It has been a while since I loaded any, but 8gr of PP under a 230gr FMJ at 1.260" OAL would yield right at 900fps, from my G21, a good service round simulator, notwithstanding the wow finish (lots of flash).
Hey, Kent. I loaded some up today. I went with 7.2grs of Power Pistol, and used Federal Large Pistol Match primers. OAL used was 1.26". Now I am thinking I may have screwed up by not seating to 1.23" OAL. I am hoping it won't make too much of a difference. Bullets loaded were Remington 230gr FMJ.I'll be happy to give you what I have;
I consider Powder Pistol to be on the edge of the fast to medium burning powders, so what does that translate into? With the .45 ACP, I have found this powder gives me the best results using 230g JHP bullets. Now 230g FMJ bullets will work, but I did not get the same level of accuracy out of them... not sure just the way my tests came out so I will not list that data.
Power Pistol will easily give you an accurate round out to 25 yards, the trade out is in the "felt recoil".
Bullet - 230g XTP HP (Hornady)
Primer - Federal Large Pistol Primer #150
Powder - Alliant Power Pistol @ 6.9g (best over-all load)
Powder range - 5.5g up to 7.1g (Hornady Reloading Manual 9th Edition)
OAL - 1.230"
Velocity - 845 fps
Test gun - Glock G21 w/4.60" barrel
I tested 7.1g up to 7.3g - accuracy was still very good but the recoil was not really that much fun to shoot!
Velocity I achieved
6.9g - 845 fps
7.1g - 870 fps
7.3g - 898 fps
Just a side note, I tested 3 230g FMJ factory loads (Federal, Remington & Winchester), the average velocity was 814.5 fps. I tested 2 230g XTP & XTP +P loads (both Hornady), the average velociyt was 887.6 fps. Hornady's manual lists MAX charge of 7.1g @ 900 fps out of a 5" barrel.
Just some data & food for thought when you are trying to achieve that kind of velocity using PP.
Good luck and be safe out there.

Thank you, Kwesi. I won't know until I get to the range, but I loaded with 7.2grs of Power Pistol and a 1.26 COAL. What sort of spooks me about Power Pistol is the data for it is all over the road. I think part of the problem is the reload manuals show different OALs.My results for Power Pistol:
230 gr PD FMJ
6.8 gr PP
CCI SPP
COAL 1.258
864 FPS
I wouldn't pull them unless you think they're dangerous.Thank you, Kwesi. I won't know until I get to the range, but I loaded with 7.2grs of Power Pistol and a 1.26 COAL.

Speer goes with 1.26". Hornady, depending on the year, goes with 1.23" or 1.1" ( for min spec chambers)...for 230gr FMJs.
You get to a point where you just don't know what to believe. Speer data shows 8.1grs with an OAL of 1.26" delivering 900 fps. I have read numerous postings of people on different forums reaching 900 fps with 7.2-7.4 grs with the same OAL. That's one hell of a discrepancy...and these are people shooting G21s. There shouldn't be THAT much variation.
Now I am wondering if I just don't need to pull what I loaded and start all over.
Thanks, MSW. I will try them when I can get to the range. The brass I used was only once fired factory PMC, and I inspected it very carefully, so I am not worried about a kaboom. We gotta watch that when we reload for our Glocks!I wouldn't pull them unless you think they're dangerous.
Shoot them. Different guns if you have them and see hoe they feel. Look for flattened primers, etc.
You can also email Alliant powder company. I have and they've always responded.

Now all I need is a chance to get to the range!
Almost exactly the velocity I came up with using similar load w/Power Pistol. Very nice, thanks for posting.BTW: this is the load I ended going with primarily because I loaded it also for a buddy shooting a full auto Mac-10:
6.6 gr PP
230 gr PD FMJ
COAL 1.260
CCI SPP
835 FPS
NOTE: all were chrono'd in Florida in hot humid weather.
