Carbide bushing..

[tar12]

What would be the min. length? Dia.?

[Al]

I just went 3/8" long, same length as the Savage ventliner.

As far as diameter, whatever will fit, mine were 1/4", but can't see why smaller wouldn't work.

I think Pete uses 1/2" in length hardened bushings.

Al, remember when you looked at my SMI breech plug and the carbide bushing was so thin we almost couldn't tell if it was a bushing or not?

It's tiny, like maybe a bit more than twice the diameter of the vent hole which was .03". So far so good.
