Accuracy International users won't be surprised by this, but I know the question comes up from time to time about the repeatability and accuracy of the AI when you switch barrels so I thought I'd share this and maybe others will chime in too.
I have a left-handed AI AT. I have a 6XC barrel, 6.5 Creedmoor barrel, and two .308 barrels for it. I've got a class next weekend so I wanted to get everything setup and ready for it. I put the 6.5CM barrel back on it. The turrets on my scope were zero'd to the 6.5CM, but I had been doing some load development with one of the .308's and had moved the turrets off zero, but not reset them. So I put the 6.5 barrel on, changed my turrets back to zeros and went to shoot. The buddy I was shooting with that day wanted to start at 1065 yards and work back. We setup an 18x24" piece of steel and drove back. I ranged it with a Terrapin X to confirm distance, laid down and shot. I'm a terrible wind caller and it took me a couple rounds to get the wind dialed in, but the picture included is the target.
Yes. That's ditch weed behind the target. Anyway, the 3 shots below the line were 9.0 mils and the one above the line is 9.1 mils. So what's my point? My point is that I swapped barrels and trusted the system to remain accurate and repeat and went straight to 1k yards. AI's system is excellent. I've also done zero checks where I shoot a 10 round group, one shot at a time and remove the barrel between each shot. If you're on the fence about an AI. Don't be. They're outstanding rifles.
As an aside, I used my Zero Compromise Optic ZC420 for this. It's quickly becoming my favorite scope ever.
