One of the biggest selling points for me before I moved on from my theoretical Tikka build (and I did have to deals set up that fell apart) was the one size fits all actually length and prefit shouldered barrels. But when I did the math and really thought it through, the cost savings after considering buying the tools, barrels, ammo and time to verify, getting a stock/chassis I like, etc, it didn’t outweigh the benefit and convenience of just having multiple barreled actions in the R700 footprint.
