My wife took over my Tikka T3 LS 270WSM. Actually I bought it when we were still engaged and I wanted her to come out hunting and I wanted something smaller than my 300WM. Soon after I bought the same identical rifle for me.
Both shoot 140gr Accubonds. SHe prefers the factory WS ammo over my reloads.
Taken elk, moose, bears and deer at various distances. All clean kills.
My wife's longest shot was about 400m on her first Mulie Buck-dropped 1 shot. She spent alot of time at the range with me and knew her rifle. Plus the BC reticle in the Leupold VX3 scope helps too.
A 7mmRM with 140-160gr bullets (Accubonds) would be good too. I personally not a fan of the 7mmRM. Too each their own!!
