Wont feed Sig target ammo
So far this barrel works ok. It is a tight fit but it fits. I have tried 2 target types of target ammunition in it so far. Federal red box (1030 fps advertised) and Sig Sauer Elite Performance (1250 fps). Both 180grn. Without the surpressor the barrel won't feed the Sig at all but feeds the Federal fine. With the supressor it feeds both. The failure is in chambering the next round in the magazine. The round gets hung on the upper part of the chamber.
