dj,
My 350 is a .22. In stock form it was giving me 22.5 FPE. Then I velocity tuned it and it gave me 24. But it was a beast. Now it has the Vortek PG2 kit and is doing 21. It's still a beast, but it's a much more controlled beast. It currently has my Bushnell Banner 6-18x50 on it. We'll see how long it lasts. I've heard that the Hawke Airmax scopes are pretty tough. They are expensive, but not nearly as expensive as say a Bushnell Elite. Regarding the Centerpoint on my 34 Panther (detuned to 15.9 FPE), hopefully I got lucky and got one of the tough ones. By the way, I do like the PG2 kit but now Air Rifle Headquarters has a new tune kit for the 350. Hmmmm.
