I've begun the process of information gathering on tikkas for a potential rifle build. I'm confused now. If this has been asked, mods are more than welcome to delete it. I'm looking at a 6.5 CM varmint. I would like to eventually make it a switch barrel setup with another bolt and barrel like a 300wsm. If I decided to switch to a LA mag for a longer COAL and a LA bolt stop from MT would I also have to switch to a LA bottom metal?
