Exactly- all you have to do is swap the bolt stop and get a long action mag. Pretty simple conversion.I believe all tikka actions are same length so all I need to do is change the bolt stop or modify it and replace the short action mag with a 30/06, 270 mag and everything should work well for short Med or long action cartridges with a standard bolt face. I’m starting to lean towards the 6.5x284. Now my next question is this... my 6.5 creed with rl 26 gets me 2950 in a 24” barrel, where would you guess the 6.5x284 would put me with a 23” barrel?
I have a 6.5 Sherman and while I enjoy the round, having a few extra steps to form brass initially can be a little annoying. Grabbing factory ammo off the shelf for my 6 Creed is much more convenient when I find myself lacking time to load. I’d go 6.5-284 over the 6.5-280 AI for that reason. Also, the tikka mags might limit your OAL on the 6.5-280 AI.
