This is my new toy! Brian Thurman (Veradium air) calls it his Bulldozer tune!!I didn't have any time to go to the range to sight her in or do any testing yet.im hoping I'll have some time this weekend. I did however fill a 55 gallon drum full of water and shot a 180 mr.hollowpoint Which by the way delivers over 300 pounds of energy. The shot I took was with the gun only filled to 2500 psi and this bulldog is capable of 3500 psi.but my scuba tank is only 3000!so Ms.Thurman tracked down AoA 74 cu ft tank for me and should be on it's way to Hawaii by tomorrow!.i would recommend him to anyone, not just for Bulldogs but anything airgun related. I'm new to pcp,and I'm glad I know someone like him who is willing to help,work with and communicates with his customers. I can't wait to give this beast some attention!!
