Called Nosler and tech told me to expect 4450 fps with about any powder suitable for the 40 ballistic tips. Worked a few loads for my tikka. I will chrony them and report accuracy.
I just bought a box of these and am wanting to load for my .22-250 with a 22" barrel. I tried to find load info but all places I have tried have the older manuals. Any help will be appreciated.
