My Tikka is stock, stock barrel etc. Changed the bolt stop out and used the 06 length mags to be able to get a longer COL. The Tikka is a long action, the bolt stop makes it a short action throw. I'm getting a bit over 2700FPS with 8208 XBR and the 185g TSX. Charge is 47g but that is about max, I would start much lower. The Tikka's have a rather long throat. I have taken 6 deer with this load none were beyond 75 yards all were pass trough's and did not recover any bullets. Exit wounds were rather massive. In my Tikka right about moa at 100y.
