[QUOTE="coyotezapper, post: 2831228, member: 20438"] 24" will work fine. With N570 load 180 to 3025ish fps (around 77 grs) 3.60" OAL 63K and fine tune from there. This is based on a case capacity of 84.5 grains and 70 degrees with an OBT of 1.228. A different temp and case capacity will affect these numbers somewhat. This will give a 98.5% burn depending on your lots actual burn rate. Good powder for heavy bullets in 7PRC. [/QUOTE]
