    Does anyone have any load data for a 257 Weatherby Accumark? Just picked one up and wanted a head start on my load data. Thinking about 115 - 120 grain pills. Thanks in advance.

    I use RL25 in my WBY mag 26" barrel. It gave me max loading as close as I could get to WBY loads.

    cbaker,
    I have a lightweigt in the .257 and use 115 ballistic tips over H1000(work up from 72)3.305OAL for best grouping and highest velocity. They have performed very well for me. I had expected more damage from that bullet but it has done minimal damage on whitetails,mulies and antelope and usually drop in their tracks. I do like the load from speer using their 120 bullet(BT)over IMR4831. Check Speer book for this load.
