Mine is a Ruger No. 1 factory except for set trigger .Here is load data for 130 XXX :
74.0 gr IMR 7828 , rem mag pr. , 3.475 COL = AVG.VEL 3415 with ES of 40
75.0 gr. IMR 7828 , CCI mag pr., 3.480 COL = AVG VEL 3487 with ES of 8.5
Data based on three shots .
I like going faster and straighter so the second load is what I settled on . Every bullet / powder combo I tried in this rifle would do to take a-huntin' , but I've found 7828 always works best in Weatherbys .
You may find out differently , of course . What you won't find , I'll bet , is a cartridge you like better !
