So I’m building a 10/22 for my youngest son to shoot NRL22 matches with. I would like to keep the rifle as light as possible to help him with the off hand shooting and maneuvering around barricades. I would like to use one of the Kidd light weight aluminum barrels. I’m just concerned that I may have the same problem with it I had with the whistle pig barrel I put on my oldest sons RPR. It shot a lot faster than all my other rifles. So fast in fact that just about any match ammo I shot was coming out of the barrel transonic so the accuracy with traditional match ammo was crap. I wouldn’t really be concerned but a friend of mine with one of the Kidd barrels says his shoots unusually fast too. He uses supersonic ammo so it’s no big deal for him but I like to use subsonic match ammo. If all of these aluminum clad barrels seem to shoot fast for whatever reason I’m just going to buy a Feddersen and we will have to work with him on ways to maneuver the additional weight.
