[QUOTE="royinidaho, post: 167843, member: 2011"] I appreciate your quandary. Replies to your post should be quite revealing. I'm betting we'll learn tons from the replies. I used two of the more popular computer codes to give it a go (not Exbal) and go scattergun results. I see why I'm more comfortable using drops at distances. OK here goes: (Hope I don't get beatup too badly;)) RSI: Sea level bc = 0.346 At elevation bc = 0.350 PointBlank: Had to set the MV to 3130 to get 3095 @ 10yds. BC = 0.238 I'm thinking I could 'guess' the bc closer than these results:rolleyes: Am [B][COLOR=Red]REALLY [/COLOR][/B]looking forward to other's results. Thanks for the opportunity. [/QUOTE]
