An Ohio-style rifle in .40-.50 would work well. Here is mine:
Weighs but 6 lbs and the 30” bbl is more than manageable. I’d choose a .45 for in the woods deering work. Won’t knock a woman over but will knock Bambi over just fine!
The .54 is a great “middle of the road” caliber.
It can’t compare to the more effective .58 and .62s on big game, but for deer sized and below, it’s a very good round and is way above anything smaller.
I turned several guys on the forum on to those guns when they hit the market from that collection.
I didn’t buy one myself as I figured they were too valuable to shoot, and I’m no collector. Still should’ve gotten one.
