Same case trim O.A.L. of 2.100 (book recommendation trim to 2.090)
Same C.O.A.L. "book recommendation of 2.860" for all the wsm's 270wsm, & 300wsm, & 325wsm & 7wsm.
Model 70 Winchesters typically have a pretty long mag. I don't know what your Tikka mag is.
I'm having a 300WSM built on a long action Model-70 specifically for even longer C.O.A.L.
But I have a factory Model-70 in 270WSM that the C.O.A.L. runs 2.915 with 140 Accubonds .015 off the lands, & I still have plenty of room in the mag.
