Vara i may be wrong but didnt the xm shoot a 223 or was it still the old mini 30 bullet?

the 30 is close to a 30-30 but the 223 is way way faster

Mustang i like the old flintlock, ive got a thompson center 50 cal with 4 power scope, have never shot a deer with it(special season) yet but ive shure raised heck with the gophers around here with it
