How do you determine the right round for your gun? Do you test all the rounds you worked up all at 100 yards and then 200 yards and then run with the ones that have the best group average or the best average at what you plan to zero in at? Also, do you clean and shoot cold bore all three or four tests shots or just in between test groups? Sorry if this is pretty basic stuff but I am just getting into reloading. Thanks for the help guys!
