RL 17 with a 140 partition
max should be 46.7 grains at 2840 FPS with the 20"bbl .
rule of thumb is to start 4.0 grains lower and work up .
min should be 42.7 grains at 2594FPS with the 20"bbl .
recoil using the RL17 powder and a 8 pound total weight rifle ;
max , 14.53
min , 12.17
-------- just something to think about -----------
my girlfriends 7-08 I'm using a 120 nosler ballistic tip with 39.0 gr of H4895 . accuracy is great in her X-bolt . 2716 FPS with a 22" bbl . with an 8 pound total weight rifle , her free recoil is 9.60 lbs .
max load is 42.2 grains at 2841 FPS with 22" bbl , free recoil 13.23
hope this helps , Jim
