Seems I read somewhere that one maker, I think Saginaw, used "broached barrels" and that they were more accurate. How about it you Guru's, whats the story here?

It was RIA who developed the idea of a Broached barrel for the carbine. Underwood seems to have been the leader of it's use as the amount of time and work was very small compared to the standard methods of cutting rifling into a barrel. Not all of the makers of carbines used barrels with the broached rifling. It was found to be as accurate as cut rifling and with just two passes with the equipment to rifle a barrel at a rate of 50 an hour compared to 11 an hour with the cut rifling system. A big improvement and one of the reasons Underwood barrels were considered to be the best of the Free Barrel progam.
Bruce, Did you see the want ad in the latest CC newsletter? There's a member selling the barrel rifling drill and broaches from Saginaw.
Chris, No I did not notice the ad. I can just guess at what he would want for them. Might be nice though to have in an advanced collection.
What is the process for a broached barrel?
I'm not familiar with it.
Thanks,
Phil
