content: Does anybody know the calibers involved here? I'd give anything for a lever-actuated rifle in 308, or, God forbid, 300 Win Mag. Especially if the rifle had a heavily militarized action [in the style of the Mossberg 590A1 militarized shotgun]. Browning used to make a BLR in 300 Win Mag https://en.wikipedia.org/wiki/Browning_BLR But I don't think Browning makes it anymoar [???].
