I bought an xcaliber 24" 1/7 twist 5r rifle+2. Before my first shot found issues w the chamber hornady match and 103gn black were getting stuck in the lands. They rechambered it and no more powder everywhere. Then i went to the range w 100 108gn match. I followed their break in cause of the issues i already had. It wanted to group but not repeatable then one round hit just off the backer into the dirt. A few groups later i took a shot and heard 3 impacts (wtf) two hit paper and the holes were big. A guy that was at the range happened to be a local gunsmith and he broke out his borescope and found (attached pics) this. He wouldnt give me his professional opinion unless i brought it in, he just went hmm and get ahold of xcaliber. There is def barrel material sticking out into the barrel. You can feel it when cleaning and in the first few rounds i found bits of charred patch and brass shavings lodged into the gas block. Could this be giving me my issues? Just want your opinions. I have contacted them a few days ago but havent heard from them yet.
