Tried some of my reloads on a Glock 21 (.45ACP).

My reloads are MBC 200gr LSWC over 5.0gr W231/HP-38. These load / shoot fine out of my XDm .45ACP. This is definitely my go to round for my XDm .45ACP.

OAL: 1.225
Taper Crimp: 0.469
Brass: R-P (I also use Winchester Brass in my rotation, but the vast majority is R-P)
Primer: CCI #300 (LPP)

The Glock 21 was owned by my Brother-in-Law. They are in the possesion of my Mother-in-Law now. My wife and I have been using it (addition to the XDm) since they don't actually shoot firearms. They won't sell it to me as it has sentimental value to them and I respect that.

I had significant feeding issues with one magazine of the reloads. I checked some rounds (after I got home) and it did not pass the "plink/plunk" test. Don't know if the chamber is just too tight for a .452 lead round or what. It did not chamber completely and did not try to force it for fear of getting a round stuck. Obviously if it doesn't drop in and drop out with pressure, it isn't going to chamber / feed easily anyway. Is it possible I need a shorter OAL for a Glock 21 vs. what works in my XDm .45ACP? Or is the round just too wide with the .452?

I've read good / bad posts regarding lead and the Glock 21. With that in mind, I'm looking for recommendations for bullets that are known to work in a Glock 21. This is strictly for range duty.

What are some recommended FMJ / TMJ / JHP bullets? Honestly looking for the cheapest possible route with some level of accuracy. These will be loaded with 231/HP-38 as this is the powder I have plenty of.

I've got a few remaining out of some sample packs from doing workups on my XDm .45ACP, but don't want to go thru the trouble of loading them up if they aren't going to work. My sample bullets are as follows:

* Berry's .451 185gr HBRN (given to me by a friend, but am interested in trying out other variations of Berry's in .451)
* Hornady .451 230gr XTP (if these work, will probably go with the 230 HAP, basically the non-expanding version of the XTP)
* MG .451 230gr JHP (they obviously make other .451 variations, but only have a sample pack of the 230gr JHP)


EDIT: It did fire commercial R-P Ammo wih issues.
 
My G21 leads (lightly) with plated bullets. Good luck with lead.

As far as feeding goes, my G21 has a pretty tight chamber at the mouth. It doesn't like it when I skip the crimp. Try doing a sharpie test to see where it's tight.
 
These are already taper crimped to .469. How much more of a crimp can I do?

I seat & taper at different steps. I use the Hornady Taper Crimp Die for the taper.
 
I'm not opposed to that, but could that cause issues with my XDm .45ACP?

Obvious concern would be pressure rising.

Where is the cheapest place to get FMJ bullets? I know that MG makes them. I would go Zero, but they've been OOS for weeks and weeks and have pretty much give up on them as they can't keep up with the demand.
 
I tried to feed 200 gr SWC reliably in my Glock 30 and gave up. I ended up using 230 gr RN.

As to your chamber drop test, if 230 gr RN drops in freely with a "clink" then it's the shoulders of SWC nose profile that's hitting the throat/leade of the barrel forward of the chamber.

Have you thought about shooting 200 gr RNFP? It should feed much better and has similar "round" nose profile forward of the bullet bearing surface. Although you can load this bullet to 1.250" OAL, but I found loading to 1.195" OAL with 5.0 gr of W231/HP38 produces comparable accuracy as the 200 gr SWC load.

Here's the thread where we discuss loading 200 gr RNFP - http://www.thehighroad.org/showthread.php?t=545996&highlight=200+gr+RNFP

BTW, .469" taper crimp seems too excessive. I usually use .471"-.472" for jacketed/plated and .472"-.473" for lead. Measure some factory 45 rounds, my factory rounds show .471"-.472".

What are your thoughts on the MBC 225gr LTC? I have some left over from testing my XDm. Or will I likely encounter some of the same feeding issues?

I'd have to order the 200gr RNFP. I'm almost out of the 3k 200gr LSWC I ordered a few weeks back and may have to throw in a box of the 200gr RNFP when I place my next order.
 
I think the 225 gr nose profile would do better if you are having problem with the SWC nose profile.

Get a drop-in Lone Wolf barrel for your Glock and shoot Missouri Bullets.

Cost difference between jacketed vs lead bullets will pay for the barrel in about 1500-2000 rounds.

Montana Gold 200 gr JFP - $149/1000
Precision Delta 230 gr FMJ - $119/1000 (they don't have 200 gr jacketed bullet)
Missouri Bullets 200 gr RNFP/SWC - $72/1000 (Powder Valley pricing)

Hmm. That isn't a bad price and I could stick with my MBC LSWC :)

I'll need to check with the CFO (wife) regarding the cost. Do you think I would need to make any adjustments to OAL on my current reloads? Currently at 1.225. Would be great if I didn't have to make any adjustments :D
 
I'll keep that in mind.

I would prefer to NOT have to do a different reload to run in the G21. If I can continue to use the 200gr LSWC and just purchase an aftermarket barrel, that seems to me to be a much more cost effective route.
 
Yes, for me, 200 gr LSWC has been very accurate bullet shot in all the 45 pistols I have used. Same amount of bullet bearing surface as 230 gr with lighter projectile.

FYI, I took a comparison picture of various 45 caliber Missouri Bullets.

Capreppy, speaking as the owner of a sometimes-finicky XD45, you cannot beat the RNFP for reliable feeding. Personally, I load them to a depth that puts the case mouth in the crimp groove then apply a factory crimp bringing the case mouth to an external diameter of .468" if R-P brass, .470" if Winchester.

5.3gr HP38/W231 reliably cycles every gun I've tried putting it through including a Glock 21, XD45, XDm45, M&P45, Taurus 1911, Colt 1991 and more. I see no reason why it couldn't be your "one-size-fits-all" round for both your Glock 21 and XD45. Most recommend 5.0gr but my XD will stovepipe that charge in the winter unless I put some counterweight on the accessory rail like my TLR-2. YMMV

What I have found recently is that 5.0 gr works well with the hotter burning Winchester primer (which all of my reference loads are tested with). With other brand primers that's got less hotter primer flames and colder winter temperature, higher 5.2-5.3 gr may be required.
 
I don't get any leading at all with LRN cast boolits in my 21SF.
