Don't have the wizard, but we bought the "trifecta" for our teenage boy. It has 12 ga/.50 cal ML/and a .243 barrel.
We checked zero on the .243 over the weekend and weren't impressed with the 100 yard grouping, but definately deer accurate.
I have decided to neck size and handload a custom load with RL 22 and 100gr interlocks to see if we can shrink the groups from factory fodder.
I think what's giving up a bit of accuracy on the rossi is how the forearm mounts to the barrel and how much tension you put on the screw/swivel to secure it. IAW, I think you could see minor variations in impact when you switch between barrels.
I'm gonna bring the little .243 into the woods this year as insurance to my Glock 20. Really wanting to shoot one with the 10mm pistol, but if a big one is out of range...
