i own a Tikka t3 in .270wsm. at 100 yrds with Hordnany Superformance 140gr, it shoot 1/2 min. i hand load 140gr nos ballistic tips in Win brass,fed 215 mag primers, and 61gr of RL19. With that load, I get .434 at 100 and 4" at 400. this is a factory gun, thin barrel. speed is 3080fps. Recoil is no worse than my Savage 110 in .270win.. I am getting it re-barreled with a heavier fluted barrel, and will be getting some Matrix 165gr .277 bullets. will work up a load for them and with their BC of over .7**, should be a shooter at 1000, just to see if I can. One of the very few things about living here in Pa. We have a few 1000 yrd ranges..
FYI, I love the .270wsm. have taken deer and whistle pigs at over 300 and all have dropped where they stood.
