    Well I have all the other problems solved on this paticular gun and it shoots real good with round nosed FMJ, But any hollow point or semi wad cutter is a different story. It will shoot 2 maybe 3 then jam. I have worked on the throat, checked the barrel fit and it all looks and measures good. I'm beginning to think it's only going to shoot FMJ bullets. I have two other 1911s in 45 and they shoot about anything I put in them. What now? I would appreciate any and all your coments and advise.

    (Shooting factory and reloaded ammo)

    Are you shooting handloads only, or factory loads also. For the SWC's, a little longer OAL is sometimes needed to increase reliability. My P220 is finicky about flat nose bullets, after testing with different OAL's, I finally found one that works good enough for plinking. ( just enough to finish off the 200 flatnosed bullets that i had )

    If you're having problems with certain factory HP's, buy a box of several different brands and try them out. A little spendy, but well worth it if you're looking for a reliable defense load.

    I have a 1911-A1 pattern .45 that would not feed ANYTHING but FMJ ball when I got it. A retired police officer had "throated" the chamber for the previous owner, another LEO, but just simply didnt have it quite right. It can be a "little tricky" to get the chamber throat angle just right, and to completely deburr and polish the feedramp. I picked up another barrel, and had another VERY COMPETENT LEO friend throat that second barrel, and polish the feed ramp, and to this day, it will feed ANYTHING that I give it to digest. Please understand that I am not knocking your work on the pistol so far; I am just simply stating that it can be ever so slightly tricky to get it "just right" without removing TOO MUCH MATERIAL and leaving the cartridge in the chamber without enough rim support. I picked up the other barrel, because I felt that enough material had already been removed from the original to "further work" it. My 1911 will feed both soft and hard lead round noses, hollow points, the "truncated cone" medium/soft lead 230's that are considered a cheap "ball ammo copy" for inexpensive "bowling pin" practice, etc. Pretty much anything at all; and it will feed it reliably whether the gun is held straight, "TV Gangbanger sideways", or even upside down.

    Most 1911 feed problems are magazine related. Do yourself a favor and purchase a few Wilson Combat, Metalform or Chip McCormick mags.

    If the pistol is a new purchase, did you give it a good cleaning and lube before going to the range ? Do you own more that one mag ? If so, is the problem the same with both mags ?
    The Springfield shouldn't need any work on the barrel throat except maybe a little polishing on the feed ramp. Don't change the angle on the feed ramp.

    I could go on typing all day but it will be faster for you to read this link. :)
    Pay close attention to the barrel section.

    Shooter, Do you think these mags will be better than the SA factory mags?

    I have never had a problem with SA mags. Now you were having a problem with wad cutter ammo. I use Metalform Mags for my LSWC ammo and they work everytime. For carry, Wilson Combat. CMC are good mags also.
    Always test new mags as I have seen a few different brands, mostly factory, that are pure junk. Carry the mags that work flawlessly in your pistol and use everything else for range mags.

    My last one would feed anything including empty cases. I used WWII and more recent Colt mags.

    Shooter, Thanks for the great advise! The issue was the feed ramp. I had polished it, But not good enough. After rereading the link you posted and thinking in over a while I went back and found a rough spot. I polished it smooth. Today it would feed anything I put in it SWC, HP, FMJ (all factory loads) with factory magazines. It will shoot a 3" group @ 25 yards off the bench. Problem solved! Thanks again for all the great sugestions and advise.:)

    Beth the chamber is where the round sits while being fired , throating the chamber is polishing it to where its smooth for the round to enter and be extracted without catching

    because of hammering actions on semi auto's this may need to be done a couple times over the life of the weapon ( not all need it other dont have impact) to take out the bumps caused by thousands of impacts by the slide of the chamber face

    i like diamond paste other folks use specialised tools for the chamber

    broaches files wool with carborundum powder, its metal so as varied as there are metal workers, i mount mine in a lathe and do it that way so i can measure it all as i go

    marlins do often benifit by a chamber polish , but never muish the hassle is people over do it and make the chamber loose for the ammo , chambers should be tight

    adjustments made to the extractors or feed line is preferable than loosening the chamber too much

    hard to say without the rifle and experimenting with it Beth

    either way they are a good basic rifle and once set up will last several lifetimes ..

    you'll be good to go soon enough ..
