I’m looking for something that you can change calibers on. I read somewhere here that you can do that with a bolt change of some sort. I would also like to be able to change barrels if I ever needed to without sending it to someone else but it to be done easily and accurately. I also would prefer rem 700 footprint so of course there are options upon options for stocks, triggers etc. What action should I look at? I want accuracy, great accuracy. Caliber is not decided at this point. I have a MPA BA 6.5 that shoots great and I do like it. But I can’t change anything as it has a first gen Curtis axium.
