50-70 barrel diameter

[labop]

Could someone please take their caliper and measure a 1868-70 barrel at the front barrel band. I'm looking for a number like 0.770" Thank you! labop

The diameter at the barrel band of the model 1868 is .813

I got .812 on mine. So same as musketshooter.

I'm always amazed how close a tolerance Springfield could hold 150 years ago. Thanks for the numbers. labop

And I've long wished...

they had paid as much attention to groove diameter tolerances...
