[QUOTE="timberelk, post: 1406725, member: 100952"] Nosler Ballistic Tip 140 grain 7mm. I found the lands by taking once fired brass from my chamber and barely placing a bullet inside the case mouth and then slowly chambering it so the rifling would push the bullet into the case mouth. I did this about 20 times and came up with my lands at 3.002” OAL. I use OAL instead of my Hornady ogive guage because the nosler BTs only fluctuate by .001-.002” when you measure base to tip. Can’t get to the lands because loading the bullet out .203” ish inches would be well beyond my internal magazine and I’m worried about how much the case mouth is holding onto the bullet. So when the bullet seated for an OAL of 2.800 the bullet stick outs about .890” and the total bullet length is 1.365” so that means right now the bullet is seated .475” inside the case mouth. I’ve read that I want at least .284” because this is a 7mm caliper (.284 caliber) So I guess I can really only Seat the bullet out .191” further out or I can go deeper if that would help? Idk?
