[QUOTE="cape cove, post: 1419301, member: 95503"] There are many good slow burning powder for the 257 WM,of which RL-22 is one. In my 257 with a 117 gr Sierra Gameking I use a max load of Rl-22 with a Wea case, and an oal of 3.265 and Fed 215 primes. Accuracy is .75 MOA and vel is 3350 fty/sec from a 24" barrel. If you are new at reloading espically for belted mags, don't forget to set your sizing die up to headspace off the shoulder. If you set it up to head space off the belt , case seperations will likely result. JMO [/QUOTE]
