Looking to build on a tikka action with mag bolt face and considering a 7mm saum or 6.5 PRC. Main use will be generally Mtn hunting so about 8lbs with optics, and fairly compact. Likely going with a lilja No3 contour, 23”ish barrel. But main thing I am debating is 7mm saum vs 6.5prc. For those who have had both or either one, any feedback on pros/cons would be appreciated.
