    Mine runs right at 2735 w/SMKs or VLDs.

    And is a dream to load and shoot.

    The sorry thing even has a tupperware stock.

    Its a great 1200 yard rock breaker....Whooo Hoooo....

    I get between 2765 fps and 2800 fps with 91 grians Retumbo. Thats with a factory 26" tube. Its deffinatly on the hot end of the scale, but its where the gun wants to shoot. I highly doubt that you would gain anything by going to an edge... maybe with a 30" tube, but then still marginal.
