Anyone beside a No.4 barrel with a measuring instrument right now?

[newcastle]

Looking for 3 dimensions if so :
- Confirm length of barrel from receiver to muzzle as 25.2 inches.
- Length (depth) of threaded part of barrel internal to the receiver
- OD across the threads (I have it as .995 inches and a 14 TPI V thread)

Sorry, I am of no help on this one, mine is still mounted to the action, and I won't be pulling it off.

OVERALL length: 25.230"
Threaded Tenon length: 0.685" +/- 0.005
Breeching thread: Nominal 1.001" x 14TPI WHITWORTH., Dia of thread with crest flattening: 0.996" MIN. Effective dia.: 0.9553" - 0.9523"

Got a little project going?
