There are some options on the market that have user changeable barrels (and therefore, potential caliber changes compatible with the same action). When the MK22 first came out, I thought is was super cool. Now that I have learned more about scoped shooting, I'm wondering whether having the ability to swap calibers is even useful for a long range or precision application.
If you change calibers on a rifle that is already zeroed, it seems like the shooter would need to DOPE a bunch of different holds for the calibers his scope was not zeroed with. If you zero with .338NM and then switch to 7.62 NATO for whatever reason, what do you do with the optic?
Would it just be a matter of recording a different zero stop in your DOPE book for each caliber? And if so, how practical is that in actual practice?
Does the weapon have to be designed from the ground up for repeatable zero when switching barrels?
Thanks in advance for any insight.
