[QUOTE="Pdvdh, post: 397273, member: 4191"] Broz, Remember my Shooting Chrony post? :) I suggest a good set of chronographs set up to run in tandem, or the Oehler 35P with the proof channel. I can say with high confidence that running quality dual chronographs in tandem (or the Oehler 35P with the second Proof channel) will accurately identify ES & SD. I've explained this in prior threads, so I won't rehash it here. The set of [U]quality[/U] chronographs (or 35P equivalent with its dual recording capability) is typically the more accurate method of obtaining MV also, rather than guesstimating MV based on drops - IMO. The only way one could ID MV with drops is if one absolutely has the correct BC entered into the ballistics software, has properly accounted for atmospheric conditions, operates the software correctly, and is a dead-eye of a shot (you pass that last one with flying colors). I will acknowledge that [U]IF[/U] Bryan Litz's G7 BCs are [B]all[/B] dead on the money, you should be able to come close to your actual MV with extensive shooting like you're currently doing. And I give Litz's G7 BCs the benefit of the doubt for being correct, based on the limited testing I've done to date with 1000 yd chronographed velocities for three separate bullets. I do think Bryan has his act together and is producing quality BC data. So I think Eaglet was on the right track respecting the Berger BC and looking at MV (based on the Shooting Chrony if nothing else :D) as a source of faulty input data. You enter valid input data into LB, and it will produce accurate predicted dope. Keep an open mind. You may end up surprised what quality chronographs (you have to have two run in tandem to have any basis to trust the data - IMO) are able to do in the way of capturing accurate velocities. From repeated observations on this Forum, many invest $3000 to $6000 on their rifles & scopes and then go sour on chronographs based on their purchase, and experience with, an entry level model chronograph. And those conclusions are probably well deserved - [U]based on the use of a single, low end chronograph[/U]. Even with a quality chronograph, the only way to establish and separate valid recorded data from the faulty recorded data (which will occur every now and then), is with the second chronograph run in tandem.
