Think I have run into a problem here!!!

Well, all I can say is, keep shootin' and keep postin'. So far I've only shot 3 shots @1100 or so and haven't walked out to see where the third one hit.

I'll just watch from back here and learn. Thanks for posting those kinds of details.

Kirby, please could you post your final input into Exbal?

Seems that the downrange values have huge differences with other's programs output...

I'd like to have the complete data set you entered, most importantly Pressure.

thanks

50, any chance your barometric pressure was different. can't see it making that much difference but might explain some of it.add to it a little difference in velocity, humidity, altitude, and wha-lah. 25 MOA!

Kirby, I would be surprised if the BC of that bullet remains constant and at that range the error is exaggerated. As you know Sierra lists several BCs for their bullets at various velocities.

Hi Kirby
Long time follower, little time poster and very little experience past 500yrds.
Another factor you may want to consinder is the compounding effect that you would get from a 100 yard zero. Now I know that it would have to be out by about an inch at a 100yds and thats probably not the case but any small descrepancy would be magnified by several time at 2700yrds.
Cosidering the temps, the slower velocity, maybe the range finder is out a little bit.
All these things could add upto 25moa, maybe working from a 3 or 500yrd zero might shed some light.

All the best
Peter

25moa? I'm happy that the gun goes off when I pull the trigger! [img]/ubbthreads/images/graemlins/smile.gif[/img]
