I have the same problem with Sierra's 135gr MK in my .270. I can only get to ~.040 off the lands.
YMMV, good luck.
Jamie6.5 thats an excellent standard that I think I will adopt. I just didn't feel comfortable with the bullet barely seated in the brass. I assume your measurement does not include the boattail section of the bullet, and is just straight wall that actually has contact with the case neck.
I sure didn't know that Cooper freebored their barrels (like Weatherby) and it makes me wonder just how important bullet distance from the lands really is.
