    Fellas, I am all but out of Retumbo for my 338rum and there is none to be had any where. I am going to try some vv n570 after seeing that there own load data shows a lawer proof 2760 somthing out of a 27" barrel I believe It may match my retumbo load @ 2805 from a 28" barrel.
    What I realy need to know is does any body have any experience with the temperature stability / sensativity of n570 plus what kind of velosity of 300gr loads in the lapua / rum thanks PC401

    I load a MAX losd of Vv570 behind 250 bergers in my 338 RUM. My drop data worked well out to 1200 yards going from a balmy 80 in MS to a very dry 35 in New Mexico.

    If you don't mind what is your load with v570 with the 250 vld's in the RUM?
    Thanks
