About 6 weeks back, I purchased a Savage Hunter 11FCNS AccuStock in .223. I finally got some time this weekend to load for the rifle. New lapua brass that is 1.750" long. Brass was run througha Lee collet die to square up necks. I can't get the bolt closed on these cases, so I tried some old Federal cases that were run through a RCBS full lgt die with the same result. Both the Lapua and Federal cases will chamber in .223 mini-Mauser. Before I get on the phone to Savage customer service, is there something I'm missing? The rifle presumably was test fired by Savage. Any and all input would be appreciated? Stoney
