[QUOTE="Mike6158, post: 332697, member: 1039"] I tried something a little different the other day. I had determined distance to the lands in my Sendero with a Stoney Point tool, Sierra bullet, and calipers. I loaded a dummy bullet, used the mic gauge to get a baseline reading, and proceeded to load 6 at .010 off of the lands. Just for grins I loaded a round into the rifle by hand. It started giving me some resistance before being fully chambered. :cool: I extracted the round, seated my dummy round (basically an sized and un-primed case), "painted" the bullet ogive area with a black magic marker, and seated the round / closed the bolt. I extracted the round and looked at the ogive area of the bullet under my lighted magnifier. The lands had left marks in the magic marker ink at least 1/8" of an inch long. So much for using the Stoney Point correctly. I got at least 5 "good readings" so I'm not sure where I went wrong. When I checked the rounds that I loaded for my VTR they were fine and seemed to at least be off of the lands (your point about variances is well stated). Somehow I messed up with the Sendero (7mm Rem Mag). That said, I continued the black marker check, increasing seating depth .002, until I could see just a trace of land mark on the ogive. I called that "on the lands", mic'd the bullet, and backed up from there. I haven't shot them yet. That should happen on Friday. [/QUOTE]
