I've fired the Co-Pilot (Non class-3) with some of the willy whup a$$ Buffalo Bore ammo. It wasn't something to curl up to at the bench all day, but I've fired alot worse.
Never fired the Bushwhacker, and I wouldn't want to without the full stock. I've no doubt it'll be a little more uncomfortable, but I wouldn't want it for Benchwork, I'd want it for general use woodsloafing, canoeing, etc.
Granted, it is a bit silly in the pistol chamberings, but I can see alot of good in the .457 that can also chamber 45/70 as well as .410 shotgun shells. The 350 grain bullet at 2200 fps seems pretty noteworthy.
a class 3 is a bit of a PITA, but it's still just paperwork, $200 and a little bit of waiting. (State Troopers are very gracious about signing them in my area)
well worth it if you truly like a particular firearm.
My thoughts are quite similar to Munks' in that "tactical" means nothing to me. I don't believe in tactical guns, knives, flashlights,coffee cups, fishbowls, or anything else with that name. "Tactical" is nothing more than a term intended to manipulate the ignorant masses.
My rifles have earned thier keep. They've been carried for countless miles,in rain, snow, wind, dropped in mud and rivers, thrown in canoes, light aircraft, and still fired every time with lethality. they are good rifles for moose, bear, and caribou, though they remain distinctly unattractive. I don't think I'd feel foolish relying on them to protect my family. I'd still rather not have them referred to as "tactical" though.
