I ran all the way up to 69gr(2995fps) w/ 195s, this was a hot load. N565/H1000/RL26 may be a better burn rate w/ 180s, but N570 may get you to pressure. You'll need a drop tube to get more than 68gr in the case.Have been contributing and keeping up with this thread for a year+, and am now getting ready to work up a load with N570 and 180 gr VLD’s. Was thinking of 62-65 grains, but seeking any and all input. Ultimately seeking 3000+ FPS. Thanks!
