[QUOTE="25WSM, post: 2099585, member: 38048"] Spot on Tim. I don't know one Smith that says where is that Reamer print so I can cut this chamber to the proper depth. They say where is my go and no go guage. I built them with both guages and they end up the same. The problem is you can't just measure the guages because they hit the chamber in different spots. The Sammi guage with the 40 shoulder hits the full shoulder but a regular go guage hits the neck shoulder junction. So you really can't measure them against each other. But dropped into a cartridge head space tool they both sit flush. Or on a complete chamber both guages show the same amount of bolt close on them. If the Sammi chamber was really .014 shorter the bolt wouldn't even begin to close on the standard guage. Or if the Ackley chamber was .014 deeper then the Sammi no go guage would just let the bolt cam over easy and still have play. But this is not what happens. I do 5 different AI Chambers and use the standard go as a no go on all of them. Got the Sammi guage for 280AI and was a waste of money because it shows the same as the standard go. I just ask other Smith's to try both guages and see what they show. I know what it will show because I've done checked at least the last dozen or so I built the last couple yrs. The proof is the guage in the chamber not the numbers on the Reamer print. Shep [/QUOTE]
