Ive found a couple really good loads after extensive load development for my tikka 7 mag ( stainless). 60.8 g imr 4831 , 3.24 coal , barnes 150g ttsx , Hornady brass, fed match 215 primer, right around a .5 inch group at 200 meters (224) yards. Absolute nailz at this distance but for some reason my speed sucked, I"m just shy of 2800 fps. The load i settled in on was 69.2 grains of reloader 25 , winchester brass, fed match 215 primer, 3.29 coal , 160g accubond . i have 2 different 4 shot groups under 2 inches at 300 meters, one was today feb 11 2021, speed on this load is right around 2900 , not the fastest loads but extremely accurate.
