.25acp barrel diameter

[nearly]

What's the diameter of a .25acp barrel from the rifle on one side to rifle on the other, also what is the correct chamber dimensions.
Thanks for any help.

Nearly, the bore diameter is nominally .251". You can get a chamber print from Clymer I beleive for the asking. They've always been willing to send me one when I asked. George
