    ]The chanber size on lone wolf barrels will fit most if not all factory loads. Really dont know for sure because i shoot cast bullets. I have purchased three Lone wolf barrels, 9MM, 10MM and 40 S&W, all three gave me problems and had to return for chamber resizing. Now 31.60 a pop. Chamber Micro readings on all three were at or less than the size of any of my reloads.

    The trick is to send in three of your cast reloads before you order. Talk to the people by phone, to avoid the expense and head aches. Seems not allowed to specify by email a chamber size.

    if you only shoot factory ammo, I am sure you will not have a problem. If you size your bullets down, that may work. I always size mine just a thousand over. Lone Wolf writes on Glock talk that reloaders should size bullets to fit the lone wolf version of tight chamber size. Or pay the price of custom reaming.

    When I talked to Lone Wolf, I was told the barrels' specs were cut for jacketed bullet diameters.

    Well, I got 9mm/40S&W barrels (replacement and conversion) for my Glock 22/27 to shoot "LEAD" reloads primarily. Yes, chambers are tight (much tighter than most factory barrels) and reloading with larger sized lead bullets (.356"/.401") require more consistency on my part with more precise taper crimping - http://www.thehighroad.org/showthread.php?p=8088665#post8088665

    If you already bought your LW barrels and want to enlarge the chamber, I enlarged a G27 Lone Wolf chamber using automotive wet/dry sandpaper on this thread - http://www.thehighroad.org/showthread.php?t=561116

    For me, I like the tight chamber as it translates to better case support. The brass case wall don't expand as much and resizing the spent brass takes much less effort on my part. Less work-hardening also seem to extend brass life as I have not seen a split case in a long time.

    LWD likes to think "match" means super tight and they cut chambers to min. spec. My 9mm barrel was too tight, but my .45acp barrels have all been fine. No issues with any KKM or Storm Lake barrel.

    I have LW barrels for several of my Glocks: 19, 23, 20, 30 and a .357 Sig which works in both my 23 and 27.

    I've had no problems with any of them. They all work just fine with jacketed bullets in round nose, hollow point and flat point. Bullet brand is of no significance.

    They also work to perfection with my cast bullets in Round Nose (9mm and 45 ACP) and Truncated Cone in all of them.

    I've got a Lee six cavity for 175 grain SWC in 10mm/40 cal but haven't tried it since I've had a several thousand TCL and RNL run with no problems.

    You do need to get COAL and neck diameter set so a loaded round will drop with a "ker-plunk" into the chamber and fall freely out when the barrel is inverted. But that's been SOP for decades.

    A friend of mine buys lone wolf barrels for all his Glocks, they all are picky on ammo. Factory barrels work 100% on the same ammo the LW don't like.....
    I'll stick with factory barrels in my Glocks:)

    LW barrels are cut tight for jacketed diameter bullets. If they won't reliably feed/chamber factory ammo, I would contact Lone Wolf.

    If your jacketed reloads don't have enough taper crimp to return the flare back to flat on the bullet or using plated bullets sized larger like Berry's/X-Treme, you may need to work on your reloading consistency more. If you are reloading larger sized lead bullets, you may need to have the chamber enlarged - http://www.thehighroad.org/showthread.php?p=8093783#post8093783

    When I got my Sig 1911 TacPac, I knew it had a tight chamber. Well, it had even shorter start of rifling with almost no leade. About 500 factory rounds I shot to break in the pistol fed/chambered fine. It had feeding/chambering issues with MBC 200 gr LSWC at 1.260" OAL with .473" taper crimp that worked fine in my M&P45. When I decreased the OAL to 1.240"-1.245" and taper crimp to .472", the feeding/chambering issues went away.
