Actually, the 10BA comes chambered in 300 Winchester Magnum, 308 Winchester and .338Lapua (long action). Insanely heavy (15 3/4 pounds) with no optic and a 0 MOA cant rail on the 300 and 308. The 338 comes with a 20 rail standard and it has a steel hinged wallet price of $2394 MSRP.
The 300 and 308 is 1-10 twist, button rifled and the .338 is 1-9.
Add A 2 pound optic and another pound for a bi-pod and you are almost at 20 pounds with 4 in the magazine....
.........and I thought my 11-111 was stout.
