Just my experience but whenever I get something “versatile”, I end up not really using the versatility. For one, it’s not as simple as changing the barrel. Often needs the hammer weight changing, esp. if the caliber switch is big. Then there’s the retune and zeroing again. Then after changing to 30, some situation will arise where I need the 22. At some level, I thinks it better to go for one caliber (say 25) and change projectile/speed. Or just plan on having 4 PCP rifles, or 8 if you have separate slug and pellet guns, plus a few pistols, a couple big bores… and an arrow shooter (or two). Of course, if you’re on the road, thats not gonna work. Of all mine the Leshiy classic is the easiest to flip but they’re as rare as hens teeth. Tough as they come for the rigors of traveling too. FXs not so much IMHO.
