[QUOTE="Calvin45, post: 1953039, member: 109862"] My own experience has led to a standard practice in which I only experiment with getting real close to the lands if I cannot find accuracy with a “normal” amount of jump. I never preemptively start load development anywhere close to the rifling. Starting near or on the lands is a great way to learn how stupid a person feels blowing primers at under-book-max loads that should have been fine to start with. When I was newer to reloading vld bullets, while nothing new of course, were really catching on, all the rage, and for hunting too! Vlds do generally shoot best while kissing the lands but the “wisdom” cleaned from this by many and repeated online was that the same would be true for other bullet designs, that the less jump the better, that the goal was to get as close as possible, that rifles with freebore would never be as capable of fine accuracy as rifles without...it’s not the case. If you’re shooting vlds or other ultra-high bc, slippery contour, long boat tail, little bearing surface bullets then yes, to lands we go! For everything else I’ve found there’s little benefits and lots of potential downsides to this practice. If I don’t feel like spending lots of time fiddling and tinkering for accuracy I typically just load a Nosler ballistic tip/accubond or a flat base hornady interlock to max book length and a grain under book max and more often than not can’t complain, at all.
