[QUOTE="Edd, post: 1706789, member: 30592"] The current fad seems to be 1.5°. I don't think it makes much difference. It can be done either way. It is easier and cheaper and arguably more accurate to have the throat angle an integral part of the chamber reamer. Floating gives you the ability to choose a bushing that is a good fit with the barrel bore. Even though a fixed pilot that was the exact size to fit would have less slop than a floating, floating is the best choice. I think .0004" smaller than the assumed bore diameter would be appropriate. There is no standard. It will vary based on the opinion of the designer. You have to check the SAAMI specs of the individual cartridge you are thinking of. [URL]https://saami.org[/URL] [/QUOTE]
