I found that comparing VLDs to BTs and partitions had a different length to lands on the VLDs, which doesnt make sense to me. I repeated several times with an "ogive measurey thingy" that EDtoomanyletters lent me, and it does appear that distance to lands is shorter on the VLDs (should be the same for any bullet of same caliber right?)
I even thought about the longer VLDs bottoming out on the measurey thingy but it would make it longer
