I am alot better shooter than my score showed but had I been shooting 300fps or over, being off by 5 yards like I typically was would not have made that much of a difference.
You would be surprised how far you are off even at 300 fps on a 5 yard misjudged target,BOTH the 280 and 300 will probably only yield a 1" difference on impact from 1 to the other on a 5 yard misjudged range.BUT both will be way off the mark.
I shot 260 fps1 year for ASA and on a 3 yard mis, I only shot a 1/2" lower than I would at 280 fps.
