Just loaded my first few rounds of some cast and powder coated Lee 200 SWC. Went to test using my Springfield XD and immediately had failure to eject/load. Had to rack the slide to get fired cartridge out, no stovepipe though. COAL is 1.235, should i loud out longer? I have no previous experience with this round. BTW, they are crimped using the Lee FCD. 20210925_170926.jpg

looks good in pic
suggest a bit more taper crimp and make sure you are full sizing the case.
I run the die down on to the plate and back off a quarter turn.

same here on sizing, it has a pretty hard crimp.
 
Tried a plunk test again, while it was flush it would not turn freely, really rough, maybe it should be shorter?
 
Your title should read Failure to Eject. May need to move this to the Gunsmithing forum.

If I reading this right is the round fired and failed to eject.... The photo above show what the end results is.

A couple of things to check. Make sure your TC is 0.469- 0.470". If the neck is not tapered the base may be hanging on the sharp edge during the extraction. I would also check your extractor tension. This is the best guide I know of for fitting and adjusting the extractor. May not work for your top ejector but it gives you an idea on what to look for.

The first pic ain't coming in real clear but it looks almost like it's crimped too much. Maybe the case is getting into the rifling and being pinched in place when the bullet tried to move?

Triee 5.2 and got the same thing. Wont fully extract.View attachment 1027748

Bullseye is a pretty fast powder. The chamber pressure can drop on a combat tuned pistol quickly. When I see that kind of failure my first suspect is the powder-spring tension combination.
I have the same problem with my Springfield Armory Ultra Carry and Ramshot Competition with 200gr X-Treme plated round nose.

never had this problem before, its like the extractor is not fully grabbing.

If your pistol is regular "XD model" with flat bottom slide rib, it's a well known issue that extracting case rim will hit the shoulder of SWC on round in magazine and you will need to use RN/RNFP bullet as no amount of adjusting crimp, OAL or extractor tension will help - https://www.xdtalk.com/threads/45-swc-jamming.58545/page-3#post-1075507

Springfield addressed this issue with "XDm model" by angled slide rib that extended down further to push on top round in the magazine so extracting case rim could clear the shoulder of the SWC bullet.

Finished round should fall into the chamber with a "plonk" and spin without rubbing then fall out freely. If not, it fails the "plunk test" caused by case not fully resized (Test resized brass before seating bullet), OAL too long with bearing surface/shoulders of SWC hitting the start of rifling, bulged case neck rubbing the chamber wall (Use thinner case wall brass to see if it helps), etc.

But if failure to extract issue is caused by flat bottom slide rib not pushing on top round in magazine to cause extracting case rim to hit the SWC shoulder, only change from SWC to RN/RNFP bullet profile will help.

It wasn’t clear from your OP if you have never reloaded with SWC, or .45. If the former, you’ve stumbled on to the “how many ways can a SWC jam a gun” discussion. Some guns and magazines will run these all day without issue. Some won’t.
The COL can be very finicky on a per gun basis. Usually the shoulder should be a thumbnail thickness above the case mouth. A few thousandths can make or break that, either way. And, SWC molds aren’t all the same.
Google “1911 magazine lips” and you’ll get an education on how even the mag will affect feeding. Your XD isn’t a 1911 but the principle is there.
I wanted to shoot these in competition since they cut a huge nice round hole but couldn’t live with the FTF/FTEs so they run in the revolver. Some day I’ll work on this problem again, but, good luck and let us know what you decide.

^^^^^^ This ^^^^^^
From the pic, the extractor is letting go before case clears chamber.

Test: Will the gun fire extract/eject cleanly if magazine is loaded w/ only one round?
(i.e., case is ejecting past an empty magazine at that point)
 
If you think it is the extractor slipping off the care rim then take a machinist pick and see if there is a build up of powder and gunk inside the bend of the extractor. This happens to mine and when I keep shooting, it just keeps getting packed in there tighter and tighter and fills up the curve until it holds the extractor away from the rim far enough that it slips off the rim on the way out of the chamber.

Bullet diameter to fit throat .451" Some of the Lee bullets need a shorter then normal COL, round nose , i think?

Round in magazine knocking fired case off bolt face. Adjust magazine or try different magazines.

Try 4 grs Bullseye & work up to 4.5 grs. This will change slide timing. For maximum velocity, change to a slower burn rate powder. Screenshot_20210926-091657_Chrome.jpg My guess.:thumbdown:

Concur on more taper crimp. Try taper crimping down to .468” at the mouth.

Here’s a pic of my similar reloads taper crimped to .468”. Perfect feeding in two 1911s.

I see there have been 5 posts with suggestions since LiveLife posted in #14 and what he stated is a known fact and well discussed on the XD forum. I too went through all of this with an XD Mod2 and no amount of adjustment or bullet seating or bullet sizing would make it work. If you read the threads you will find that there was a complete change made to the slide on the XDm to get it to reliably cycle and feed SWC profile bullets.

Yeah, I will probably change profiles.
 
TO THE OP: Don't give up on that bullet just yet.

Will your cartridge "plunk" fully home with a longer OAL?
More exposure of the lead shoulder provides a softer transition past the case mouth.

Note cartridge on the right.

********************
See if such seating/shoulder exposure addresses the transition problem.

Did the OP plunk test his handloads before shooting? Extractor issue is very difficult to diagnose without a hands on approach so I won't try. I see a couple problems with some replies and most common is "add more crimp". In the many thousands of semi-auto rounds I've reloaded I do not crimp (32 ACP, 380 ACP, 9mm, and 45 ACP). I deflare with a taper crimp die and get 99.99% good feeding/chambering. I have 3, 45 Auto guns and two love the H&G #68 (RIA 1911 and HP 45 ACP carbine. Ruger P90 chokes on the SWC once or twice per magazine) clone but I normally seat the bullet deeper than the pic in post #23, the shoulder just a few thousandths above case mouth.

Good post.

This would be the definitive test where if single round in the magazine feed and extract without issues but won't extract with 2 or more rounds in the magazine to determine if the extracting case rim is hitting the shoulder of SWC of top round in the magazine.
