[QUOTE="brian b, post: 75216, member: 2797"] AWB, I ran it through my program it lists the 140gr Failsafe at a b.c.of .372 (very optimistic) at 3100fps and a zero of 300yds you will need about 25min. of elevation for 1000yds. the problem is that from my experience the accuracy of these bullets degrade rapidly at long range. Try a 150gr ballistic tip with a b.c. of .496 at 3000fps with a 300yd zero you will still need 21 min of elevation but your groups will shrink dramatically. Good Luck B [/QUOTE]
