    I have a Rem sps ss in .257 Wyb. and cant fing a starting place for Retumbo with the 115gr vlds can some one give me a starting load? and how you got that starting point.

    Is any one using Retumbo in there .257 Wyb. ?

    I am going to by one pound of H-1000 and one of Retumbo to see which one works the best.

    Hi Nape,

    Try a start of 66.0 grains, for about 3100 fps, and work up to a max of 69.6 for 3300 fps.

    Drop me a line on the Berger site and I'll be happy to forward the complete set of tables for the 257 WBY. Tried to post it here, but the margins wouldn't stay aligned.

    Hope this helps,
