What's good load data for 200gn LSWC that will NO JAM MY GLOCK 21?

[Lead Waster]

Hi guys. I have some (like 450) 200gn LSWC "laser cast" bullets that I bought a long time ago. They never fed well in my Glock 21. I'm using an aftermarket barrel for shooting lead reloads.

I think what is critical is the OAL. I've tried a few but still get unchambered rounds. I'll be using Clays for these rounds.

Any advice on this? I've even set some bullets with the shoulders right at the case mouth, which is probably not a good idea, but they don't consistently chamber either.

What's a good starting OAL? And really, what's going on? I'm assuming that the lead lip of the SWC is catching the part of the chamber that the brass is supposed to sit (Sorry, my nomenclature is uneducated!). Does shallower of deeper seating help?

Is the critical part the shoulder of the SWC or where the nose is?

Thanks for any advice on this!

Eh? Maybe I just need to read it again.........

Sorry, too much rambling.


Basically 230 gn RN bullets feed fine in my Glock 21, but I'm having a devil of a time getting 200 gn LSWC cartridges that feed well.

So I'm wondering if anyone has any good load data that they use when loading that round, hopefully, for that gun.

And maybe some insight as to why that bullet profile hangs up on feeding.

Thanks!

Lee FCD - get one!

I shoot SWC's out of my G30 all the time. The thing with hardcast bullets is they are 0.1" thicker than FMJ bullets of the same weight. Do you see a slight bulge on the case from the bullet? I used to have a problem feeding LSWC's in my G30 but the advice I was given pointed me towards the Lee Factory Crimp die. Once I started using it I no longer have feeding problems with my G30 factory or aftermarket barrels. I recommend you purchase a FCD and give it a try.

FCD FTW

I use 4.5 grains of titegroup for a 200 grain hardcast SWC. It's a light accurate round out of my 1911's, Flock and Revolver.

I actually do have a FCD for .45. I must be using it wrong because I believe there is a little bulge around where the bullet is seated!

How deep do you seat the bullet? What's your OAL? THanks!

OAL for me is about 1.250 make sure mouth is crimped to .470-.473

From what I have been able to decipher from your post:
You getting FTF's (Failure to Feed)?
I seat 200 grain LSWCs around 1.248 or just so that there is around 1/32nd of and inch or one thumbnail width where the lead is above the case mouth. Taper crimp to remove any trace of belling and no more.
Quite a few people swear by the LEE FCD, I consider them a waste of money! Properly adjusted dies do not require a FCD.

i had serious feed issues in my ria tactical until i figured out the optimal COL for my chamber and feed angle (is that the proper terminology?). surprisingly, how much i belled my cases (within reason) didn't have a whole lot to do with it. 1.225, 1.230, and 1.250 with taper crimps to .470" had failure rates (failure to feed or to return to battery) of about 5%. now i've settled on 1.241 with a simple taper crimp and the rounds chamber perfectly.

the drop-in-chamber headspace test is fine for gauging headspace, but it doesn't accurately reflect the trajectory of the round when it is chambered. that is, the highest round in the magazine (next to feed) still sits lower than the chamber itself, and the round therefore enters the chamber at an angle. so if a round passes the headspace test, that DOESN'T mean it will chamber reliably.

another forum mentioned a good way of checking whether a round will chamber reliably WITHOUT going to the range and performing a live-fire exercise. first, load a magazine with the round in question. then, chamber the round while GUIDING THE SLIDE gently and slowly forward with your nonshooting hand. (yes, i realize it's something you'll never do in real shooting.) if the round chambers smoothly that way, it'll chamber smoothly when the slide slams forward under tension from the recoil spring. if the round gets caught or the slide doesn't fully return to battery while you're guiding the slide forward, you've got to decrease your case expansion, increase crimp (whichever die you may be using), or, as in my case, optimize COL (increase or decrease--you'll have to figure this out).

The best way is take the gun apart and use the barrel as the gage. The feed angle is controlled by the frame ramp and the magazine follower in some cases the barrel will have to be opened up a bit more to feed certain bullets.

I've knoticed a lot of modern combat pistols have issues with swc and wc bullets. I personaly would try to trade them off for some rn or tc bullets.

I could not get SWC to work in my G 30.

[Chief-7700]

My guess would be the Glock ramped barrel will not accept the Olgive of the LSWCs

i find the bear creek 200 swc feed just fine in mine but the same load hangs up in the mag of a xd45

i got some 3 groove 200 grain swc and i cant get them to feed in squat so 45 revolver they go
