[QUOTE="highdrum, post: 2364961, member: 13732"] I'd say start around 68gr, accubond typically prefer a lot of jump I think? Start 50k off lands? Load from 68-72gr in 0.4gr pairs. Shoot each individual pair at separate aiming points, you'll see 3-4 charges that are touching or 1 hole. These are the speed node the bullet likes to go, they'll likely be 90-110fps apart. Once you find the speed node, it's time to test seating depths I'd try -35, -42, -50, -57, -65 you'll find something that shoots well. This is how how do my load development. Powder test done at 100y, seating depth done at 500y. [/QUOTE]
