I can squeeze 25 normal play shots before the velocity drops on my 68's and tuned to 250-260fps) ... but they are far from stock, if I get all gangsta it'll drop to an even 20, I can eek out 30 if I play like a pump, but the last few are close range only and low velocity.
Dave G I tinker, therefore I'm broke!
Further, now that I've found the MCB BST ... I've recently sold my house and moved under the bridge down the road ... but I've got lots of markers.
I have no life, I'm just a dad in constant flux between baby naps and 8yr old tantrums.
