I think I have at least 7 tikkas currently and have done a few more builds with others. My latest I just picked up is a 6.5 prc build. This smith did use the tombstone lug after facing the action . This is a first for me, but the rifle shot the factory 147 for him in the .4s, so I'm not going to argue. The m+ mags are a great short action option. I've been running the 180 eldm s for giggles out of my 7mm08 at 2.95 and the damn things shoot, even though everything on computer says factory barrel and sea level should not. I've had at least 5 tikkas re barreled and not one has ever needed any truing
