Custom barrel?

If you have maxed out reg then reduce hammer spring till the group tightens up, the avenger’s hammer is a bit too heavy IMO.
That is the plan. However I still want a slug that will be accurate at max or near max power. So far the only slug that has done that is the Apex 41 grain flat nose banded boat tail. Max power they are right at 70 FPE and almost as accurate as jsb 33.95 pellets.
 
How did it do with the 4 pellets? Sounds like maybe you did get a bad barrel.
Pellets is fine. It is very good with the jsb 33.95 both the original and Mk2's. Also got Seneca 35.8 grain, Seneca 43.2 grain, and air boss 33 grain copper coated pellets. Oh and I lied I do have some 37 grain ones made by someone on eBay but they don't shoot good as I don't believe they are made properly. Very large skirts and still lots of casting flash not cut off. The avenger is definitely a pellet barrel but it has been interesting trying to find a decent slug that will work with it.
