    I tried Retumbo in September 2013, and managed to get chronograph 12-ft readings of a bit more than 3000 fps. with the 160-grain Woodleigh bullet. However, I'll not suggest a starting load, nor will I post the loads I used. There is too much variation in bore and chambers among Ross M-10 sporters. Brass capacity and strength will vary considerably, depending on source -- original or formed from something else. Bullet diameters can be a problem for the unwary too.

    If some forum member knows of a source of pressure-tested data from a reputable, reliable ballistics lab (Hodgdon, Lyman, or one of the bullet mfrs, I wish they would share that information in a post.

    Thanks.
