Ive always been able to find a great load well under max be very careful as you approach max loads.
If a gun is shooting 1/4 MOA at 50 yards & 2 MOA at 100 yards .something is wrong with your setup .
Scope loose, action screws loose bad bag setup etc
Get reloading data from a solid source
Have loading data from reliable sources, just curious as to what 603 used. I question the new scope, may have to change out to a known good scope. 1/4 MOA at 50 yds for best 4 shots, seems like this bullet always throws one high/low.
