I want to rebarrel my LH TIKKA M595 to either a 6XC or a 6.5 Creedmoor. This would mainly be for my dad since I will mainly be using my 280AI SAKO. He has some recoil issues due to a bad sholder. It would be for deer and smaller out to probably 500-600yds. Anyone using these or have other suggestions? I was thinking of these two since they can seat the long vlds and still use the magazine. Harder to do with a 243 or 260. Its a short action by the way.
