Thanks for the info. During break in I only fed it Hornady 55gr HPBT. After it started having problems I tried a few other makers and it still would not feed. Most of the time it would not pick up a round. And if it did, it would jam it in the throat. If I pushed up on the bottom of the mag that's when it would grab the round and then it would not feed it. The model 12 BTCSS in 223 is not a cheap rifle, it is one the more expensive guns Savage makes. For that money it should function every time with no issues. I hope Savage can fix it. If not I am sure they will replace the rifle. Thanks
