I bought a Tikka t3, and its a great ,very accurate rifle, with heavy bullets only. 69 grain sierras make this rifle shoot incredible, but I think I can fine tune it a little better. I tried some match grade 52-55 grain bullets and it throws them all over, maybe because of the 1:8 twist? So would anyonne like to share some pet loads and maybe I can fine tune this baby a little? My best group today was .77 for 5 shots.
