Ever hear of Dennis Quackenbush? Very talented craftsman. I've been following BB's posts on the Quackenbush Outlaw .457 long action air rifle (see
Part 1 and
Part 2). Also check out
Big Bore Shoot 2008.
No big bore maker is as popular as Dennis Quackenbush, however. Dennis turns out hundreds of guns every year, and yet cannot seem to catch up with the demand. He's been making big bores longer than any other maker today. He started by making up parts for 10 Paul air shotguns in the early 1990s. He sold them as kits that a skilled worker could turn into a close copy of the original .410 air shotguns made in the 1920s.

Dennis Quackenbush is working toward an air rifle with the muzzle energy of a .50/70 black powder round. That's a .50-caliber 425-grain bullet leaving the muzzle at around 1,200 f.p.s. (from a 32" Springfield barrel). That's 1,359 foot-pounds, and such rifles were very successful buffalo rifles in the 1870s, sometimes taking bison at ranges up to 500 yards. It's a lofty goal for an airgun maker, but I wouldn't bet against him.
