Lands and Grooves for Typical .45

[BigSkyRambler]

Can anyone tell me the typical land and groove measurements for a typical modern .45 ML bore?

I think the question may be too broad. It might be best to send emails to barrel makers to find out exactly what they bore their rifles.

Last time I looked at roundball barrel specs it was maybe .012” deep for square bottom, .016” or so deep for radius bottom rifling for the specific manufacturer I was looking at. As @Cattywompuss suggested, likely best to contact manufacturers for current specs. Plus there is a chance they will make a barrel to YOUR spec. And just to make the point, have a question for you. What is typical gas mileage for a modern SUV? No need to answer…..

This is now moot. Rifle NOT .45.

The first reproduction .45 I had, the rifling in it looked like a Remington centerfire with very narrow lands. There just is no industry standard.
