    I recently asked Lonewolf Dist. for further info on conversion barrels for .40 to 9mm. Due to 1% of 9mm conversion barrels are affected by the poor performance with WWB and Rem. (UMC) ammo. JR Sheppard of LWD was nice enough to give me a speedy and informative reply.

    On your web site you have the statement below. I was interested in the purchase of one of these converion barrels. Also when are they due in?


    Notice: About 1% of our 9mm conversion barrels are affected by the poor performance of Winchester White Box (WWB) and/or Remington (UMC) 115 grain ammunition and may fail to extract reliably. For more information email us direct at lonewolf@lonewolfdist.com

    Here is the info you requested:

    About 1% of our conversion barrels are affected by the poor performance of Winchester White Box (WWB) 115 grain ammunition. This rare failure is too low a percentage to make an issue, however it is one we are well aware of. The fix to resolve this issue is quite simple.


    1 Clean and lube your slide and barrel.


    2 Shoot 1 mag to 1 box of good quality +P or +P+ ammunition through the barrel.


    3 Go back to the WWB 115 gr ammunition. If it runs... great! If you experience more failures you will have a couple choices to make.


    Fix A Reduce the recoil spring weight to 11 to 13 lbs. Cost is about $25 for stainless steel guide rod and reduced power spring.


    Fix B Shoot 124 gr or a better quality 115 gr ammunition exclusively. WWB 115 gr ammunition is no longer a valid option.


    What causes this problem? Several issues come into play.

    1 The 40 slide and (40 conversion) barrel is thicker than any standard 9mm slide and barrel. This extra thickness equates to more weight. The combined extra weight taps the energy of the "weak" WWB ammunition to its complete demise. It simply lacks in power and fails to reliably eject the spent round.


    2 Every once in awhile a Failure To Feed/Failure To Eject (FTF/FTE) is caused by a fit issue. We resolve fit issues by pumping +P or +P+ ammunition through the gun. This hot ammunition provides extra pressure and the pressure will positively align any and all components. Once they are all aligned there is no longer a fit issue. The FTF/FTE is usually resolved.

    FYI: WWB 115 gr ammunition is the weakest sub standard ammunition you can purchase. This ammo is also known to produce failures in all standard Glock 9mm pistols.

    Well, there may be issues with WWB ammo in their barrels, but I'm not sure the blame can entirely be placed on one type of "weak" ammunition. This is assuming the WWB they are referring to is the 100 round Value Pack 9mm 115 grain FMJ, and not the similar-but-different 50-round Winchester White Box 115 grain FMJ. I have not tested or chronographed the 50-round-box ammo, but I have shot a few boxes through my Glocks with no stoppages/problems.

    I ran 4 different brands of target-type 115 grain FMJ 9mm ammo through a G17 and G17C last year, with the results listed below. Of the four, the WWB was the second most powerful, based on velocity.

    ----------------------

    Factory "target" ammunition, caliber 9mm Luger, fired through a Glock 17 and 17C.

    Temp: 68-70 degrees F, velocities measured 10 feet from the muzzle.

    Each test string was 10 shots in about 90 seconds.

    DJ I tend to agree, that the WWB is not as impotent as believed. I have never had that ammo FTF or FTE, but than I have to listen to people like yourself who are more balistics savey. I very shakey now on buying a conversion barrel.

    I call BS on the above statement. It's LoneWolf in a feeble attempt to place
    the blame on someone else.

    I've shot thousands of rounds of Winchester white box ammunition in the
    last 15 years. NEVER one single issue!

    The thing I don't understand is if WWB ammo is the problem, why does it function poorly only 1% of the time?

    Yep,....sounds more like Lone Wolf only having a 99% product reliability rate
    and attempting to find a scapegoat.

    I disagree with Lonewolf's statement. A factory G23 and a factory G19 share the same recoil spring and both function 100% with factory ammo. Same goes for the G17/G22 and G26/G27. The problem is the barrel and not the ammo.

    PS--even a G19C will function 100% with Winchester USA.

    I think that both Winchester Value packs and PMC Bronze ammo may have recently weekened their loads. I base this on the fact that the WWB shoot so softly compared to other ammo - they just feel week, and the PMC's will barely eject from my G-34. I recently watched a fellow with a brand new G-34 unable to run a complete mag of PMC through without a failure. After giving him a few of my bullets, it was determined that his ammo was week. The PMC brass only cleared the slide by a few inches.

    I have never had a bad round of Win. White Box yet.
