[QUOTE="highdrum, post: 1811348, member: 13732"] Freebore stops where the chamber is no longer 0.278 diameter(2.619 on print) , at that point the lead/throat starts which tapers from 278 to 270 at 2.771". The bearing surface of the bullet is 277 diameter. That will only go into the throat maybe 30-40 thousandths before it engages the lands. Any more than that you're jammed. This chamber has nothing close to 178 freebore. Freebore is usually 1 thou larger than bullet diameter. This chamber has essentially no freebore. [/QUOTE]
