[QUOTE="cb4128, post: 1992073, member: 80069"] I have been using Retumbo in this rifle for the last 2 hunting seasons with good success, but finally got my hands on some VV N570 to try out with the 156 gr berger elite hunters. I have a custom chamber that allows for a COAL of 3.480" with the 156gr bullets. I did a pressure test (never hit pressure signs, stopped at 71.0gr), found flat spots in velocity at 3,065fps and 3,137 fps and settled on the following load: New Nosler brass Federal 215m primer 70.3 gr VV N570 156gr berger elite 20 thousands off the lands or 3.460" COAL / 2.765" to ogive 3,137 fps avg (roughly 50 fps more than my Retumbo load, and more accurate) *pictured is my 3 shot group at 100 yards with this load - front bipod, rear bag, includes cold bore shot **also pictured is a coyote and the rifle from last year Can't wait to stretch it out to confirm drops and try out the terminal performance on some animals in the coming weeks.
