Setup: 1911A1 Springfield Armory with custom fitted Kart NM barrel and bushing, trigger work, 12# spring, ultradot mounted on slide. Has been feeding a diet of 200 gr LSWC over 4.2gr Bullseye at 1.26" oal without any problems whatever. Trying a load to use a large quantity of 200gr FMJSWC (Speer?). Test fired with 4.2, 4.5, 4.8, and 5.2 grns Bullseye. Total OAL is 1.275 (about 1/32 inch of bullet showing between shoulder of bullet and case mouth) Velocity is 741, 792, 803, 872 respectively. 4.2 grain load is dropping the empties right beside me. 5.2 grain is kicking them out about 6 feet behind and to the right. With all three loads, 2 or 3 out of a trial batch of 20 failed to return completely to batter: the round was picked up, carried forward, but the slide wouldn't quite close on it. Partially racking the slide cleared it. Looks like the top of the case mouth is just barely hanging on the barrel.
Anyone got any hints of where to start problem solving? Shorten or lengthen the total OAL of the round? Junk the jacketed bullets and go back to lead (ouch!). Stronger mainspring? Weaker mainspring? I'd like to hear suggestions.
Thanks.

Is your OAL what is recommended by Speer?

Is the chamber thoroughly cleaned from the LSWC?
Speer only markets the 45 TMJ Match SWC (same thing, supposedly but no exposed lead on the base) and they recommend a OAL of 1.275. Brushed the chamber with CLP thoroughly before trying the jacketed load.

What recoil spring weight are You runnin now.....Mainspring can't help it return to battery.....maybe load a little hotter....I don't care how far the brass goes just so it gets out and don't hit Me.....futher the better in most cases ,You may have heard of smiths that can build a pistol that will land all brass in a 5 gal. bucket....I've always called Bull$#*t on that one

If the weapon will go into battery given a sharp heel of the hand to the back of the slide, I would try a different weight recoil spring.

My first suspicion is ammo. Sounds like there is some level of inconsistency there. If only 3 out of 20 are doing it. If it were the mag, I'd think it would be a more consistent malfunction. Check crimp

Chamber dirty? Rusted? In need of throating? Undersized? All of those seem much less likely to be the culprit. Ammo is more likely.

I think I'd look to the recoil spring next. I believe the factory weight is 16lbs. Call me crazy, but 12 seems awfully light, IMO. I'll be watching this thread, fa sho. I wanna know where this one goes.

Sorry I haven't responded to suggestions lately. Paying work took precedence. I checked the rounds and they measure at 1.275, Speer recommends 1.25 and that could be causeing the rim of the case to just nick the top of the barrel, slowing down the return. Next step is to make a batch to speck on OAL. I'll also thoroughly clean the chamber and mags. Oil is no problem, lots of speckles on my shirt and range pad! I'll report back on the ammo adjustment and cleaning results. Then will look at a slightly tougher recoil spring.

Thanks. Stay tuned for the results. I WILL find a solution!

AlleyB.....Any an all of Your solutions could be the right one....I once watched a FAT SMART ASS show a pistol club how stupid He was when the problem was bad reloads , He's a self proclaimed gunsmith , a worthless SOB, the one that did the work on a slide I showed on here a few years ago and had reloaded the ammo.....My pistols will all work with lighter recoil springs than most run.....can't say why...I use the firein pin stop to slow the slide down in its rearward run so if the recoil spring will chamber the round that is enough for me....May be just Me but in Louisiana 10 months out of every year My hands are wet and sweaty , grab a slide to rack it, have it slip in Your hand and that Bo Mar open a Gash like the one belongin to a Carilina gal named Rosey Rottencrotch , a lighter recol spring might be the answer

Wild Bill, I don't claim to know anything other than how to follow instructions, and that has got me in trouble more times than I want to admit. So, with all that you and others have suggested here, I got a Wolff recoil spring tuning kit and will follow those instructions to see what I can come up with.

I don't understand what you mean. I'm rollin' on the floor about the Carolina girl thing!

DT...foreroger on the recoil spring kit...You will probably get it runnin and get some good schoolin at the same time.....by the way, last post could be misinterpeted.....I meant a lighter recoil spring might mean the slide would be be easier to rack and maybe if it slips , not get too bad a gash.....get the reloads in spec or go a little under , besure chamber is clean , then try heavier recoil springs

AllyB....look at a modern firein pin stop....You should see a maybe a 3/16 radius , May have that number wrong , no drawings handy , They are all in the shop......JMB put a very slight radius on the early 1911s.....more radius on the firein pin stop makes it easier for the slide to cock the hammer and continue rearward , henceforth less radius makes it harder for the slide to cock the hammer thus slowin the slide down and......maybe JohnTe will see this and explain it better than I can,.....playin guitar and drinkin all weekend , takes awhile to get it goin on Monday

How do the loads work with the original barrel? A custom barrel may have a slightly different chamber cut.
Don't have the factory barrel. Lead 200 SWC feeds and runs just fine with nary a hitch. Same problem on a factory stock Springfield Stainless Trophy Match when the jacketed rounds are used. So, I'm thinking it may be the rounds being just a half a hair too long. Will keep you advised.

In that case, it almost has to be the ammo.

Wild Bill, I get what you're saying there about the radius on FPS. Drinkin n playin'..... I swear you make me laff d**n near every time I read one of your posts.

Oh, I better be careful. I just got banned for 20 days this week on another forum for cursing like that....:eek:

Check crimp

I have a caspian gun with a Wilson barrel that gave me fits with te same problem. In the end the chamber was so tight I had to crimp more than usual. Even factory loads weren't 100%. Loads that worked in all my other guns weren't 100% in that barrel. After setting up my crimp by chamber checking each round in the actual barrel I got complete reliability and the ammo still shoots fine in everything else. Good for easy 2" groups at 40 yds using 4.6 gr of WSL. Very light target load. I think that powder may be discontinued but I still have a little left in an 8lb keg and a sealed 8lb with a $66 price tag on it. I am using an 18 lb spring. I also switched my sizing die from dillon to a redding. I just kept increasing crimp till it ran 100%. BTW I'm using cast 230rn bullets. Even though the crimp might be considered too tight on paper in actual use it didn't affect accuracy at all. I find a good tight crimp makes all my ammo more reliable. I really like the lee factory crimp dies a lot

Kaboom, that makes sense. The difference in the issues I'm seeing is that yours WOULD run in other guns. It sounds like DTHughes is saying these reloads give him trouble in another gun(That is stock) too. If the gun will feed SWC bullets, then these rounds have to be out of spec so far as I can tell... That and he actually said they're loaded to .02 longer than Speer recommends. Your chamber was tight as gnat booty, but his issue sounds like reloading headaches to me... I agree with you on the LEE stuff. Some folks think they're just cheapo, but I really like mine. 45-70, 9, and 45 all without issue. I have had some 45 that slipped deep into the case after being chambered(From Georgia Arms-I think they were their "Remanufactured rounds)... I would be inclined to agree that using a tighter crimp is fine as long as you get 100% reliability. I will definitely sacrifice accuracy for reliability any day.
