It may be old school, but I like the consistency of ammo that you get with a lever action chambered in .357. It’s certainly a bit slower to operate than an AR platform, but a butt sleeve increases the reloadbility. You can load flat nose, hard cast bullets for penetration and down range punch, or hollow points for anti personel. Add a four inch revolver and you’re good to go. Reliability rules. Looking at the ballistics of some of the loads from Buffalo Bore show a lot of potential.
