The problem with comparing a Red Wolf to anything else is that it applies full bottle pressure to the projectile, but in a contolled way. An unregulated airgun does this also but when you throw a regulator in it, you're restricting the pressure and flow in most cases. That's where the plenum becomes important. There are versions of the Wolverine that aren't regulated but I've not seen anyone put a 177 barrel on them. The regulated versions have a small plenum... same as the Revere, and are not really intended for monster power. They really shine where they're intended to be, though.
I've had best luck with heavy 177 slugs in the Red Wolf over anything else, including the Delta for the above reason. It takes pl 12 on the Heliboard and full fill to get 1000 fps with the 20 gn NSA's. Zan's may be a little easier as they're softer, but I've not tried them yet. I've let my testing lapse on the 20 gn NSA's but REALLY wanted to find the solution for the leading and have not yet. In the small window after seasoning the barrel before leading builds up, I've shot the smallest groups I've ever shot with ANYTHING at 100 yds, even my bolt 223 with Berger bullets... about a pencil sized hole. I've even shot pretty small things at about 300 yds with them... they just need a SERIOUS airgun to push them.
Back to the OP, I've only owned a Wolverine, of the two in question, but have repaired a couple of Regals/Revere's. The Revere's are beautiful, no question, and handle well, but I like the weight and ergos of the Wolverine more. So does my wife. I find the Revere similar to the Tarantula... looks nice and feels great in the hands but has a limited application window so isn't the best for our shooting preferences.
