What does your action measure across the widest part of the standing breech (outside-to-outside)?

Anyone have a 577 and calipers handy?

Chris,

My VC is 2.168" across at the widest part of the standing breech and 2.12" across at the bar where it joins the standing breech.

Thanks, Todd.

While you have it apart, what is the distance between firing pin centers?



Any other 577s out there?

Would a measurement from a 577/500 mag. BPE be of any help?

EDIT: this is from an 1885ish Alex Henry, pins CTC .975" The face width is 2.2"

Greener 2 3/4 - 650- 90 grain.

2.413 widest standing breech
1.232 out side to outside firing pins.


If you own a gun and you are not a member of the NRA and other pro 2nd amendment organizations then YOU are part of the problem.
