I am pleasantly surprised at the higher charged ones in my test today… 44gr of imr 4831 behind a 168gr SMK is a heavy charge but slow burner, so still quite soft shooting for an advantage in silhouette….it did hit 2.5 moa right and 3 moa low versus my ordinary zero, but groups well enough for offhand shooting! I’ll see how it does for me on Rams through 2022 and keep building my reloading toolbox.
