[QUOTE="QuietTexan, post: 2651592, member: 116181"] I'm trying to figure this out also. I'm looking at my 26 Nosler reamer print and the start of the throat (freebore and leade combined) doesn't have a length on it, but math puts it at .0335" long. My dummy round was within .0005" of this without seeing the CE specs. Mike - I've come around to thinking you were right and I was wrong on the "jump" here because the STB will be in contact with the freebore section no matter how long it is set up for the 156s. I wasn't grasping the point that the STB is larger than caliber at first. Yes. Sorry, quoted you but read a different post after mine while typing an edit and got the two confused. Pictured below is a CE 133 MTAC single Feed. STB is 0.2655" in diameter, so 0.0015" greater than caliber. The bearing surface of the bullet begins ~0.125" above the STB where the bullet reaches groove diameter of .264", so only half of my freebore length. To get the bullet into the lands I think I'd have to push the 0.0015" ovedrsized STB ~.125" down the freebore section. [ATTACH type="full" alt="IMG_4161.jpg"]406005[/ATTACH] [/QUOTE]
