Here in NY for the next short interim, Center fire rifle has slowly been getting authorized for large game through the various counties.
Previously, large game could be harvested with Shotgun (slug) or Muzzle Loader only. So I followed in a friend's footsteps and picked up a cheap .50 cal Cabela's (Traditions) Shenandoah-style side lock.
Some might consider that by using BP substitutes and Power Belt bullets, I don't really qualify as a BP user. That being as it may, this inexpensive firearm can be very surprisingly accurate. Last time I shot it, I was using Pyrodex RS Select, but any future shooting will be done using Triple Seven. It's just so much easier to clean up.
