Re: Extreme spread
Goodgrouper makes a good point. Don't get hung up on ES or SD. Sure watch it. And its important way on out there. But rely on what the target tells you. I've had loads that had even more ES than what GG tells off and had rifles shooting 1.5 inch groups at 600 yards. Of course if ES is wide and groups are wide.....
Personally ES and SD are the worst things ever thought of to use with a chrono in my opinion. In fact if you'll watch each shot , many times when the chrono says it'll be in the group its outt, and when it says it should be out and high (or low) its in the middle.....
Get as close as you can, but utilize your skills as needed.
