In .22 and .25, this is probably less of a problem.
I have actually experienced this myself: a gunsmith once shortened my .177 Spitfire barrel, after which the gun grouped like a shotgun. I had to bin it and find another Spitfire barrel.

John is a good man to know, sure he could help with anything you needed Spitfire wise
