Thank you for the data, I am just looking for a starting point. I will look at the link you posted. It’s just a little bewildering when you start looking in load books, so many powders and bullets. I guess I should have ask for info for loads on any barrel, not just Criterion barrels. I do have some 150 SST’s and some Nosler 125, 180gr. BT bullets and some 168gr. Nosler combined technology BT’s. I also have some 150gr. SMK’s, I think I’ll start with those, but eventually want to try some 600-800 yard shots. Has anyone used the 208gr. Amax’s? Thanks for the info.
