This may be better suited to the reloading forum but Im not sure as it could have to do with the gun. Ive got a problem with my STI Trojan latley. After 150-200 rounds the slide isnt going into battery. I reload my .45 ammo using a lee pro 1000 and then factory crimp it all. Im using 230 grain round nosed bullets of unknown make(I got a deal on them). I test all the rounds in the case gauge and they fit in great.

From what I can tell after 150-200 rounds the chamber is getting fouled with lead(or something) and the bullets arent chambering properly and stopping the slide from going fully ahead. If I clean it the ammo falls right in the chamber again. This has just started happening recently. Ive been usuing different lead bullets than I had previously. Is it possible that that this type of bullet could be causing my problem? It may be lead or lube but whatever it is takes FOREVER to remove. The gun always got pretty fouled but not ever this quick. Any ideas? Thanks

"...factory crimp it all..." Taper crimp? Check the case lengths too.
"...round nosed bullets of unknown make..." Cast or jacketed? Regular cast 230 RN's with 4.5 grains of Bullseye work just fine out of my Colt.
"...case gauge..." The best 'guage' is the barrel out of the pistol.

Yes lee factory taper crimp die.

cast, I figure if I used jackets I wont have this build up, so I may switch to them soon. Usualy I have no problem with cast bullets either until recently

I use the case gauge and as I stated I also drop them in the cleaned barrel and when its clean they drop in just fine

Thanks

I Have a STI Trojan 45 as well.I had the same problem with reloads,I found that I had to have the LOA of the rounds quite short,or else the shoulder of the bullet would would impinge on the rifling and the slide wouldnt close properly.This would get worse if the gun had been shot a bit.The chambers on STI's are quite tight.

Make sure that you are belling the case enough,if you arent a small ring of lead can shave off,and build up in the chamber area,preventing chambering after a few rounds.A LEE FCD die is definitely a good idea when loading lead bullets for a STI

From your post,Im not sure whether you describe a chambering issue,or feeding issue?can you be more specific?

You shouldnt be having to go to FMJ bullets in a 45 to get it to work properly.45's and lead bullets were made for each other!
 
I had the same issue a few weeks ago, it occurred after I had increased the crimp on my 200 grain LSWC's.(Factory crimp die) I dialed the crimp back a little, almost 1/2 turn, and no problems the next time out. Don't ask why, I have no clue. The adjustment took place only on the upper (crimp) knob, not the die itself.
 
Its a chambering issue. The slide isnt going all the way ahead. A good smack will put it in battery but after a few good smacks yur palm bleeds and its not so fun lol. I'll check a few things out on the press. Thanks

EDIT:
What OAL are you guys using for 230 grain cast bullets? I just tinkered with the press a little: More flare, seated bullets a little more, and used a tad less crimp. Ive got 230 grain cast bullets with an OAL of 1.23 ish. No shaving of lead and the crimp looks good. They drop in the gauge and barrel(but so did the others until I fired 100 or so rounds)

I had the same problem with my Ranger II. The STI'S have a really tight throat so you need to crimp the loads more than you would normally. My regular load fed my Glock 22 with no problem but I had to increase the crimp in order to get them to feed in my STI.
