Crosman Benjamin ePCP Rogue .357; The first big bore airgun from a major American manufacturer; Electronic valve and trigger, 6 shot rotary magazine, shrouded barrel. Presented at the 2011 SHOT Show 2011 in Las Vegas, available in May.
These were the three Quackenbush airguns that I took on the first Safari to South Africa; the DAQ .50 caliber (top), the DAQ .25 with a carbon silencer, and a DAQ .308 carbine.
Two bigbores showing the trend towards more compact design, the top is a .451 Dennis Quckenbush  built for me, and the lower is one is a Leroy Roduner .457. At LASSO this year there was a lot of interest in hunting guns that are built along these lines.
