My underwood ammo came in just now, and it must have a longer OAL, because nearly every round fails to feed. Ive been having this issue ever since I bought the barrel, but usually it was only one or two rounds per mag using winchester and hornady ammo. I dont blame the ammo, Im sure Ill be very happy with it, it is just this damn barrel is really starting to frustrate me. One or two ftf's per mag doesnt really bother me when im out plinking, but damn near every round is just too much to put up with. I wanna be able to reload the brass, and if I just shoot it through my stock barrel, in all likelihood Ill just end up with a bunch of unloadable brass due to glocksmiles, since this ammo is loaded to full power, or thereabouts. Ive considered sending the barrel to lwd to look at, but Im afraid Ill end up with a barrel that isnt much better than my stock one since they will likely just over do it on the feed ramp, instead of just a good polishing to the top of the chamber, which is really all I figure it needs. Im afraid they'll send me my barrel back in such a shape that it no longer "fully supports" the round. I guess Ive just gotta get my hands on a dremel tool with some good polish and a good polishing wheel, and do it myself. Ive never done it before though, but what could really go bad with just a polishing wheel? Unless some of my fellow GT'ers that have worked on a LWD barrel before and know what theyre doing feel like helping a fellow out?!?!
