Ballistics by the inch 22 data

I was debating barrel length on the munchkin rifle I am working on for my young son. As luck would have it the BBTI folks have 22 data now. The difference in velocity between a 16" barrel and an 18" barrel is practically nil for most loads (20 fps or less). I found it interesting that past about 12" the increases on up were not at all dramatic and if I would leave the munchkin rifle barrel at it's original length of 25" it is a losing proposition over an 18 - 20" barrel.
