Just putting this out there for future google searches.....may come in handy for somebody. I was not expecting this. I don't know if this is the norm for a wolverine. I jokingly made a comment that they must have hidden a regulator in my wolverine. The chronograph was 10 feet in front of muzzle so add 8 to 10 feet per second to all values. That comes out to an average of about 32.6 ft lbs. The groups out at 50yards this afternoon mirrored this tight spread. Here is a pic I posted elsewhere of a 10 shot group at 50yrds from today. Nikon Acculon range finder verified.
They must have turned up the juice on these since they first came out several years ago. Seems like I remember 70 to 80 shots per fill but that was with a 15.89 jsb in the 890s I think. This was 900ish with 18.13gr jsb. There was only a max 12 feet per second spread on 50 shots. Personally.....Im happy with 50 shots at 32.6ft lbs. in .22
I use the 15.9. 100 shots per fill at 925 fps.
