i'm trying to wrap my head around some specifics for the rifle i will eventually build. as far as the win mag vs the wsm for distances between 1000-1800, is there considerable difference that would warrant one over the other? i know that typically the wsm seems to get around 100 fps less with the bigger bullets. i plan on using 190-215 gr with the gun. i see some pros to the wsm just as far as reloading but it is a slight compromise in velocity from what i've seen. any thoughts?
