Gunsmithing 5R rifling land/groove width.

[Raufoss]

Hi,

Does anyone know the Land and groove width on 5R ?

I try to spec it in QL to add a new case.

Thx

I would think this would significantly vary based on the ID of the barrel. IE, 22 vs 33 cal.

Yea they're down a man in the office.
Go to this website and look at the specs for rifling profiles for some of the 22 caliber rounds. It gives width and bore dimensions. While not 5R I know Bartlein stays very close to the same percentage for the land area.
