I have 500 brand new pcs of Starline 45 Super brass wanting to be used... anyways I've always wanted to work up the 250gr Gold Dot to run around 1000-1100 out of my G21sf w/KKM barrel. Anybody have any ideas? I'm planning on using Longshot to start with, it seems to do well in both .40 and 10mm (when I used to shoot 10mm). I think the sweet spot for that bullet is within the velocity I'm looking at, it mushrooms huge and moving at that speed, is good medicine for about anything one would ever encounter...within reason of course.

I have found that the OAL makes a difference in feeding. The bullet was designed for the .45 Colt, and while the G21sf seems to chamber them all well, I've found my DW 1911 won't chamber any of them...unless perhaps I look at a shorter OAL...perhaps around 1.2"?

I will keep you guys posted on my results.

FWIW, 460rowland.com sells both a compensated and a ported kit for the G30. I would equate .460 Rowland to being a pretty hot round. I don't particularly care for thier compensator as it resembles a 1911 slide more than a Glock, although it looks pretty good on an XD.

I have been considering getting into the reloading/loading business and one of the first loads I am thinking about involves the Hornady XTM .451 250gr bullet. But I am thinking more along the lines of getting .460 brass and loading the 250grainer to around 1200fps, as the .460 brass will more than accomodate that. Buffalo Bore already loads a 255gr hardcast at 1300fps.

I ask because I think the 36 would be a good trail gun...
If I were looking for a small trail gun I would choose the 30 over the 36 just on the merit of capacity. Most aftermarket barrels will handle 45 Super because most of them tout "fully supported chambers". Then of course you need the stiffer spring. If I were going to do that project I would buy a 20, 22 and 24# spring and pick the one that the gun shoots the best with. They don't cost that much.

And don't forget about 460rowland.com where you can get a conversion kit for the G30 to fire an even hotter round than the 10MM.

I am posting to follow along because I see either a 45 super or a 10mm in my future. I am leaning toward a G30 followed by a G21 sometime later....both shooting super. Could the G30 shoot 255 gr hard cast bullets at 1000 fps? Thanks.

The 460 is very appealing, but the power level I want is 230-255 gr bullets at 1000-1100 fps. Still, the 460 is nice, neat, and could be "super" and then some

Buffalo Bore shows a 45 Super 255gr hard cast @ 1090fps from a 5" 1911, so the G30 would require hand loads, most likely, to get there. Unless you were to get a longer barrel from LWD. Then, IMO, the $319+s&h you would pay 460rowland.com might not be a bad idea. And if you hand load then those ballistics would be easy to achieve with the rowland set up. I have often thought that I would like to hand load so I can have a 250gr XTP @ 1200fps from my rowland G21. Cor Bon loads a funny looking .460 hollow point 255gr close to those ballistics-1100fps from what length test barrel I do not know.

After thinking about it, I think you are right. I did do a bunch of research on 460 Rowland about a year ago. There is really no downside. At my level of performance, I might get by without the compensator....but then I wouldn't have the style points
1. Mild 45 acp to wild Rowland will cycle.
2. 319.00 ain't bad considering he has already worked out the bugs.
3. It looks really cool too.

At the time, I had an M&P pistol. I emailed a question to them and Johnny Rowland himself emailed me back within a day or two. It seems that his venture is still small but it has been growing slowly but steadily. Now if I had any money.....

I have been fooling around with 460 for my 21 for a few months now and I am close to getting it right, without the comp or porting. But, since I want to keep within the forum rules, I will no longer post here about 460.

Awesome thread. I subscribed to follow along. I might come off as weird to some because of my quest for the perfect simple one or two gun set up. I currently carry a Ruger SP101 with the 3" barrel. I also have a Flat Top 44 special intended for hunting. They are both wonderful (haven't even fired the flat top yet due to no reloading equipment and being broke. ha!). I target shoot, plink, carry, and put deer meat on the table with the SP (legally).......but......

My wife hates revolvers, but wants a Glock. I love Glocks so why not a pair of G30's for us with a bigger G21 on the wish list for later. If I put Rowland kits on mine, we still could share brass (rowland of course), dies, bullets, holsters, 45acp ammo etc..... It just makes sense to me.

I posted this over on the 21 club. Hate to double post but think it is good information to share. Input is appreciated here too.

Ok, here goes. I started some 45 super load work using 45 +P Starline brass. I also purchased some 45 Super Starline brass as well. I cut some of each in half and felt the 45 +P brass provided more support.

Gun details: G21, Lone Wolf aftermarket threaded barrel, Wolf 24lb recoil spring. Stock otherwise.

The starting data used was lifted from this site I used Hornady 185XTP, AA#7, Wolf primer.

I'm at work and don't have the middle powder measurements however the first 5 shot string (left in picture) started at 13.0 grains and the 7th and final string (right in pic) finished at 15.5 grains.

My chrony was acting up all day and obtained some limited data. Shot string #5 (left to right in the box) was in the 1340fps range if memory serves correctly. Chrony messed up on 6&7 so I will have to redo those.

The gun functioned perfectly. Ejected cases went 5-6 feet to the right and slightly back. Recoil (in my opinion) was moderate-heavy.

I'm not seeing any smiles or any other indicators that would say to stop at this point. I've micrometered all of the cases the entire length of their bodies and I'm not finding any differences from string #1 to string #7 that would make me say "whoe nellie".

Please let me know your thoughts and what you would consider as a case head measurement that might make you take a second look. Question: Is this measurement vs a virgin unfired case or vs a starting load fired case?

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.

I've read through this thread and it seems that a 21 lb spring is all you need to fire .45 Super out of a Glock 30. However, is it also recommended to upgrade the barrel? I'm hearing this may not be the case with the 21's but not sure about the lighter slide 30's.

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.

I use two standard mag springs in each of my 21 mags. At first it seems like they just won't fit but keep at it and you will get them in the mag. I shoot Underwood 230gr @ 1100fps without any misfeeds. And I shoot .460 Rowland with the last two rounds misfeeding. That is 230gr @ 1300fps, and its always the same, the last two will not feed without assistance.

Unfortunately with the double sprung mags you won't be able to get 13 rounds in, but I am satisfied with 11 rounds in mine.

Also, you might have to remove the recoil buffer to allow the slide enough room for rearward travel, because your slide may not be going far back enough to get behind the case. I "bit the bullet" and bought a Sprinco recoil reducer to eliminate the frame contact, although I had to send it back to Sprinco so they could put a stronger sub spring in it.

The next step is a threaded barrel with comp.

Thanks,
I have the threaded barrel, and I was thinking about buying the extra power mag springs?

I have two Wolff "extra power mag springs" collecting dust with the rest of my gun stuff. My feeding problems didn't stop until I combined the two standard mag springs. You might have better luck with a different brand than Wolff.

The only comp that I think would be worth the money is the Yankee Hill Machine Co., which comes in stainless steel, not blued steel or aluminum. Good luck with your endeavor.

What powder are you using? I'm thinking about getting a 6" bbl for the G21sf. As for your post, I would try it without the recoil buffer, I've had issues with those before in other guns.
