I understand the powder bushing are marked in thousands and the shot bushing are marked as what they are, example 1-1-4 or 1-1-8.
The one I have a question about is marked - Bair/NO 6-5 1 6? I have never seen a Bair chart and I thought maybe they had some marked as PW does. With numbers meaning certain things instead of the actual measurement?
Hornady or pacific bushings are the same. I dont have a 3/4oz. to check but if you need a certain size, i can make you one. We have bosses at work with a 3/8 tapped hole in center all i do is drill the hole to larger size. They drop right in PW's,Pacific,Hornady,& the bair too. Keith
