[QUOTE="NW NM hunter, post: 3078462, member: 122861"] A few additional things, in my 7prc I run the n560 and get about 3050 with the 175eldx, so the n570 may be a little slower than the 560 in your 7prc and possibly your 6.5prc for a similar powder type in different burn rates. Another note since you stated you are moving to n570 over retumbo, when I looked at it similar with n560 over rl23 and h1000 is that above 90+ish degrees the 560 and 570 can have pressure spikes due to the heat which is why they aren't labeled as being temp stable.
