Im new to Paradox guns and Im struggling with a few questions. Ive been hunting with double rifles for years; but I haven jumped into a Paradox yet. I'll probably be using my Paradox for medium game, mostly Wild Boar and possibly Whitetail.

I think Im looking for a 10 or 12ga. Ive seen some loaded ammo; but Im open to reloading with BP (or substitutes) or smokeless. Most of the factory loaded rounds are conical, with some round ball; but Ive also seen references to three ball loads.

Ive seen barrels from 22" to 30+ inches. Is there and optimum length? Something around 24-26" seems good to my novice eye.

Is there a standard "zero" range for Paradox guns? My typical hunting range is 100yrds or (preferably) less

Im at the point where I think I know...but Im not sure what I dont know. Im sure this may sound naīve to you experienced guys. So Im open to learning--thanks
