Along with the great information provided in this thread, the Daystate Red Wolf seemed to dominate a good number of the posts. It is a gun I would like to have and just may wind up getting down the road a piece., but until then I will have to be satisfied with my Wolverine "R".
The Wolverine line has been around for quite some time, so when they added the Huma regulator, I didn't see that as a major change except for the good. The Red Wolf, although having its roots in the Pulsar is new and although there have been very few reports about growing pains, a little time to work any possible ones out, would make me feel more secure about getting one.
One of the features the Red Wolf has that is very attractive is its short "lock time," the time it takes for the pellet to start its journey after the trigger has been activated. It is said to be upwards of 5 times faster than a mechanical arrangement, like on the Wolverine. So even if you are right on target when the trigger breaks, by the time the pellet leaves the barrel, fractional movement could throw the shot. I have experienced that too.
With all that said, even with all the mechanical stuff going on, here is a 4 shot group (right side) from the Wolverine "R" 177 JSB Exacts 10.34 grain at 40 yards. Not typically this tight but more often than not, a one hole group in general (left side with the obligatory flier).
. I'm drivin' hard to the hoop to up my game! The more I do it, the more I enjoy it. In the inimitable words of the legendary John Mellencamp, "I been doin' it since I was a young kid 'n I come out grinnin'!" Like pizza and beer, it never gets old
