Has anyone been able to reproduce the results that Matt Duber supposedly shows on his Maverick Compact Video regarding shot count? The best I have gotten for 900 fps is 90 shots just as advertised. Somehow he shows he gets 139 shots off the 300 bottle and the 500mm barrel. I left him a comment asking him what the setting on his gun were for him to get those numbers - but no response. Shooting JSB 18.1 grain pellets. Thanks in advance for any advice.
