[QUOTE="lancetkenyon, post: 2661668, member: 68875"] BC comes into play at extended ranges with a 155 @ 3200 VS a 177 @ 2900. Let's just take yardage for where they drop below 1800fps. @ 6500' AMSL and 30°F (typical late season elk conditions) 155 hits 1800fps @ 910 yds 177 hits 1800fps @ 930 yds 177 wins If you want to take 1500ft/lbs of energy remaining: 155 hits 1500 @ 700 yds 177 hits 1500 @ 790 yds 177 wins So if you keep shots below 700 yds, lets look at drops: 155 @ 79.7" 177 @ 100.6" 155 wins [/QUOTE]
