Default XDm .45 FTF with LSWC

Well, I finally got out to the range with a bunch of my first few batches of reloads. My .38 and .357 mag XTP loads were great. My .38 LSWC were great and were a pleasure to shoot My .45 230 gr FMJ loads were a blast and cycled flawlessly. But my .45 200 gr Speer LSWCs were a pain.

About 25% of the time I got a FTF with the semi wad cutters. After a little research afterwards, it appears this is not that uncommon in .45s, those some swear that there XDms have no problem with LSWC. In all cases it appeard that the cartridge was not being pushed all the way into battery, and was still at an angle. No marks on the primer from the striker, but the striker was cocking. I figure that before I give up on these bullets, I should try a few things and would like your opinions.

I loaded these bullets seated as described in the speer manual, with only about 1/32" of the front driving band visible beyond the brass, which makes for a pretty short OAL. It could be that these would be less likely hang up if I seated them a little less, which is an easy experiment. Probably would not help, but may be worth a try.

I also had these loaded fairly light, since this was my first attempt with these. I would have to look at my notes to see exactly what the load was. But it may be possible that a slightly hotter load may work better.

But most likely, the lip of the SWC is just catching on the feed ramp somehow, or at least enough to take enough energy out that sometimes it won't feed all the way. I forgot to look closely at the bullets themselves to see is there were any tell tale signs like scraped lead or something.

Anyway, it seems like I should maybe experiement, since I have about 400 bullets left

Staestc,

Unfortunately that is an inherent problem with the Springfield XD as well as many 1911 Pistols. From what research I have done since I also own a 45 ACP XD is that polishing the feed ramps does very little to assist with resolving the problem. I heard one guy messed around with the length of seating the bullet but that is not my idea of solving an issue. As you stated, you might try to load them a little hotter and try it as you mentioned to increase slide speed and travel. However I doubt it will work. But the bottom line there are many including one guy who even sent it back to the Springfield Custom shop only to get it back with unreliable feed problems with SWCs. Wish we had some good news for you. Maybe someone here will as long as they are giving technical advise and not just opinion regarding a fix for your problem! It certainly needs to be someone who has had one and resolved the problem. Good Luck! But the XD is one fine pistol.

I have some thoughts on this.

Lead normally runs .452, where jacketed will be .451 with only a few being .452.
The chamber may be on the tight side and that very little difference could be a factor. Do you use a 'taper'/'factory' crimp or role crimp or just load them? For my .45ACPs, I just load them. For my .40S&Ws, I use a 'taper' crimp.

A conformation of your change in seating depth. I would try out a little and in a little.

Also, a slight increase in the charge could cycle the action with more authority and help. Don't know know your loading, so this is a long shot possibility. Short Stroking?

Disclaimer time. I don't have an XD in .45. I have a number of .45s in the 1911 form. I do have an XD, in .40S&W. I run mostly lead in my .45s (including a Marlin Camp Gun) and a mix of lead and jacketed in my .40S&W.

Keep trying variations and you will find the right mix. Keep records of your variations for later use. You have a good handle on the probable cause/s and how to address them.

I too question the crimp. A roll crimp might allow the case to seat too far forward in the chamber causing a light or no primer strike.

its how the throating is done, and the angle at which the bullet hits the top of the chamber. some semi autos will hang a semi or full wadcutter on the base of the feed ramp.

ive got two colt series 70. one was made in the 70's the other is brand new 2010 production. the only difference is how the chamber is throated. the new colt feeds full wadcutters semi wadcutters and even empty cases. the older one has a chamber like most 1911 and wont feed semi or full or empties and sometimes has trouble with certain hollow point bullet profiles.

my xdms wont feed empty cases so i doubt they would do well with semi/full wadcutters. but those arent bullet shapes i care to shoot out of my xdm.

I misread the post. I thought it was a fail to fire when I saw the no primer strike. On the fail to feed you might want to forget the swc and go with a plated Berry or Rainier round nose to keep the cost in line.

NEVER roll crimp a case that head spaces on the case mouth.

I was using a slight taper crimp. JonM's description of hanging on the feed ramp sounds dead on. I have not tried feeding empty cases, but I suspect it will be identical to what I got with LSWC. I am still going to experiment with seating depth and bump up the charge a bit. It is remotely possible that it will be less likely to hang with a different OAL.

Of course, the mold that is supposed to be here today is a round nose mold

Thanks for all the responses!

Hey Travis I had the same problem in my Ruger P90 and it was from loading the cast bullet too far in the case. Instead of 1/32 you should try a little more shoulder and they will feed properly. At least mine did. Give it a try because I went a little nuts until I tried this. Good luck Travis and Semper Fi!

Thanks very much! You give me hope. I originally loaded with 5.0 gr of Unique. The Speer manual calls out 4.9 to 5.4, so I am going to try and load some more test rounds up this afternoon with 5.2 gr Unique, and I will seat them out a bit more and see how that does. Of course, if you saw my other thread, my casting pot and .45 bullet mold came, so I might be distracted
