Just wondering, I worked up a load for my .300 Wby, and the velocity was on the high side of things, but i didnt question the chronograph, zero'd the rifle at 100yds, dialed up and moved out to 500, shot a very good group 1.5 MOA low! So now I am wondering if maybe my muzzle brake
is messing with my data some way? I will lay it all out for you guys and see what you think.
