Nosler ballistic tips in any weight or caliber have always been extremely easy to get to shoot ridiculously accurate in every gun I’ve tried. If you can find 180 grain Nosler ballistc tips I’d tell you give them a try. You won’t find bulk core locts unless you find a private buyer with old stock. I have a few hundred I stick piled from a decade or more ago along with about 1200, .311 core locts in 180 grains. I’m going to have to get my hands on a lee .308 sizing die and squeeze some through it to down size and test with my proven 30-06 core loct load to see if they shoot just as tight. Hornady I can get to shoot almost as good as the noslers in my guns but I have have to work a lot harder to get them to even as close to as tight of groups. The Hornadys are alot more finicky to get to shoot accurately"
