    OK Thanks. You have covered all of the bases like me only I was unaware of the Ace spring.

    They had some in stock yesterday.

    PS - I am going to try a 24lb ISMI spring I got from Glockmeister the other day, have been using a 22lb version of the same up till now, just a little frame battering, not bad.

    I can say this; What I have learned from converting my 21 to fire 460 Rowland is that it is a very powerful cartridge. I decided to skip the compensator, in favor of a more compact handgun, and I have learned that though the 21 seems to be able to handle it, I'm not sure that I can.

    I describe my 460 Rowland experience a little more in detail here:

    Dougader,

    Appreciate your load data and pictures of the WFNGC bullet... I am going to try that bullet out.

    The Beartooth 265 grain WFNGC hardcast slug ...What dia. did you get... .451?

    Thanks,

    Jerry

    Finally got some Underwood 45 Super on the way. 230gr Gold Dots @ 1100fps. I will see how my Sprinco likes that stuff. I just hope that my 21 doesn't get upset with me for switching up on it. I was feeding it 230gr @ 1300fps. I'm sure the frame will enjoy a little break from the pounding.

    Hmm... 45Super 230gr @ 1100fps, ME of 618, PF of 253, dia. of .451, 12 rounds on hand(with double sprung magazine). What more can you ask for?

    I shot a box and a half of the Underwood 45Super 230gr Gold Dots, through my .460 barrel. And I was using my double sprung mags. The 1100fps ran like clockwork out of my 21. I believe that the slide stop never even touched the frame during the recoil. So the Sprinco, set up for .460 Rowland, couldn't stop the frame contact when shooting 230gr @ 1300fps but it worked perfectly when shooting the 230gr @ 1100fps. Who woulda thunk it? I think that I am going to have another conversation with Sprinco about this.

    Any how. I believe that I have finally found a 45 caliber round that I can be satisfied with; The Underwood Ammo 230gr @ 1100fps Gold Dot. Shooting this ammo reminded me a great deal of shooting my old G20SF, really powerful but not too powerful and I even noticed a little flame coming out of the barrel. So now I really want to get some video of this ammo. Guess I'll have to order some more bullets.

    I shot some of the Underwood 230gr GD the other day out of my stock G21SF (with the exception of a 24lb ISMI RSA). The recoil seemed a little more jarring than my G20SF using a 22lb spring shooting 180gr XTP at 1295fps. I attributed the heavier recoil feel to the 24lb spring.

    I got no frame battering at all with the 24lb spring. Feed was flawless. I am going to try the 22lb spring out of my G20SF to see if felt recoil will be a little more sedate. Cases were landing pretty close with the 24.

    I really like this ammo. Definitely will be my new SD load for my 21/30's.

    Loaded up some .45 Super for the first time today. Used:
    New Starline brass
    9grs Power Pistol
    230gr FMJ seated to 1.240"
    CCI LP.

    Only ran 5, it's terribly hot here, right around 100 degrees. Shooting Chrony F1 @ 10'.
    Ran through Glock 21sf np3 w/4.6" KKM barrel and captured 22lb recoil spring. Recoil was there, but not brutal. Speeds were:
    1095
    1096
    1092
    1084
    1078
    Avg= 1089 fps/ 606 ft-lbs

    Brass looked good, I feel there is some more room to play here.

    Little update, I loaded up a few more and to the backyard I went. G21sf w/KKM 4.6" bbl and 22lb spring.

    230gr XTP 9.5gr Power Pistol, 1.230" (1.240" wouldn't feed in my KKM bbl), CCI LP, Starline brass. 5 shot average was 1135 fps packing 658 ft-lbs energy. Liking the 45 Super more and more! Brass looked good, I'm sure one could go a little higher still...slowly. Maybe 9.7gr next.

    Also for kicks I wanted to give Longshot a try. I almost started at 10grs which is the minimum charge for 460 Rowland...but I prefer to play it safe. I only shot 3 of each, but here it is, this time 230gr FMJ @ 1.240" CCI LP Starline virgin brass.

    8.5gr Longshot avg= 1025 fps

    9gr Longshot avg= 1068 fps


    The online data Hodgdon shows for the .45 Super is a joke, not even .45 ACP +P level. Brass looked okay and could more than likely go higher, but that's all for today.

    Great data! It's great that you can shoot 45 Super through the Blackhawk convertable-makes it even more versatel. And once you get the cylinders modded right, being able to shoot the 460 Rowland is an added bonus.

    Man, it has to be nice to be able to shoot through your chrony in your backyard. I could likely do that once.

    You are seeing a little better velocities with Longshot that I got. At 9.5 are you seeing any extractor rash or flattened primers?

    Thanks for the link for the Blackhawk convertible information. I think, at least in the case of my G21SF in its nearly stock configuration (only an RSA swap), the pressure limits may be more about timing than absolute pressure limits. To my mind, there is no reason to believe that if my Glock didn't have to unlock, eject and reload it likely could withstand 460 S&W pressures.

    Living out in the country does have it's advantages :)

    Yeah I am seeing a little bit of scarring of the brass via the extractor, nothing major but there's a little bit of bite showing. Primers did not flatten out with the 9gr Longshot or 9.5gr PP load however.

    Gotta love those CCI primers.

    At right around 1100fps with both BD and LS I start getting some extractor rash (and flattened primers, but I am using Winchester which are softer, I think if I were using Federal's they would be flatter than a pancake).

    The extractor rash is not bad enough to cause problems getting it into a shellplate when reloading.

    I saw your post on the KKM barrel. My KKM barrel does have a little more support under the ramp, but I think the chamber is very similar to my stock barrel, maybe a slight bit tighter, but still a lot of wiggle when I drop a round in and move it around with my finger.

    I am going to pick up some CCI 350's this afternoon and give them a try.

    I have been testing the Hunter's Supply 275 gr. cast FN bullet, and it's a dandy and my favorite thumper 45 Super bullet.

    I'm shooting an XDm 5.25 (sorry), but I've run them up to 1060 fps. with Longshot and nearly that with Power Pistol.

    I just sent some to an industry friend for pressure testing. I will post the results here if anyone is interested.

    I built a 21 SF for .45 Super and I am having some problems.

    The gun;
    Glock 21 SF
    5.75" Lone Wolf Barrel
    Wolff 24# spring and Guide Rod
    Recoil Buffer

    The problem is it won't cycle the next round, sometimes it jams with the round still in the magazine but the bullet sticking up to catch the slide. And sometimes it doesn't feed at all, I have to manualy jack one in each time.

    Chrony data;

    185 gr XTP - 1373 FPS @ 3 ft.
    230 gr XTP - 1213 FPS @ 3 ft.

    Any help would be much apprieciated, I REALLY want this caliber to work, It is the ULTIMATE woods carry gun if I can make it reliable.

    Hot stuff.

    It sounds like your slide is out running the magazine. You might give one of those heavier wolff magazine springs a try. Getting some additional weight in the slide assembly might help as well. I am not very fond of comps, so when I have to cross this bridge some day, I am going to try a stick on wheel weight as a test.

    Also, I had no luck at all with a buff, in .45 Super or with my G20SF.

    Thanks,
    I think I will get the extra power mag springs and toss the shock buff and see what happens.
