MM Xisico xs28 .25

Just received a MM Xisico XS28 .25 with and a extra .177 and .22 barrel. I bet it shoots as sweet as his others.

I know you just got the gun but I always wondered about something concerning multi caliber springers. What caliber out of the 3 do you think the gun was designed around? Is it a super hot .177, a perfect .22 and a pokey .25? Or is there something I’m overlooking and there’s a way to make the gun balanced in all calibers. I’ve always wanted to shoot one of his springers and see what they were like.
