So i recently purchased a nosler patriot rifle chambered in 280AI, i loaded a few rounds for break in and groups. Before i went to the range i put a bullet in to see how it chambered and the bolt handle wouldnt go down,the only way it went down was with excessive force. Im using nosler brass with nosler 140 accubond. OAL 3.330. When i put a piece of brass by itself with no bullet seated the bolt closes normal. Anyone have any ideas.
