I have worked up a load with the Berger 115 gr. Vld and 59.5 grs. of retumbo in a Savage 112 26" stainless barrel that's shooting 1/4 " groups or less at 100 yds. I do not have access to a chrono, but was estimating the velocity to be around 3075 fps. using the Hodgdon manual and what Berger sent me to come to this number. I was looking at some other loads published on here and other sites and was seeing a big difference in the velocities, + 200 fps on some loads. Could some of you give me a better estimate of what my velocity should be? Also has anyone notice how dirty your barrel will get shooting retumbo powder? Seems worse to me than shooting other powders.
