I'm looking to achieve 3.0 kgs with scope, suppressor and sling. Did you mention the weight of yours or have I missed it?

2930 pulls me up with the 77tmk out of a standard length tikka. Long Waters mag but they shoot best at 2.3" oal. Headcase's Geco brass is lasting well (but slowly disappearing into the tussock). I wouldn't like to push it much hotter - 3k sounds a bridge too far for the TMK. I get there with the 74's (standardTikka). 2206H for all.
