It depends on what action you have short or long. If you have a short action small shank you can change between all the short cartridges except the magnums. You may have to change the bolt face depending on what you have and/or what you are changing to. If you have a small caliber .17, .204, .223 etc. and are changing to 22-250, .243, .308 you will need to change bolt face too. If you have a long action small shank you can go to any caliber but the magnums you may have to put an adapter/filler into the mag well to run the short action cartridges. To go to the magnums cartridges you will need a large shank action, some have had barrels chambered for some of the mags in small shank and have gotten away with it but many barrel manufacturers will not chamber a small shank barrel to a mag caliber. The bolt heads are easy to change and are readily available. Welcome to the brotherhood of the barrel nut the possibilities are endless in what you can put together without the need of a gunsmith and minimal tools.
