[ARCHIVED THREAD] - Compact 4x?

Posted: 10/14/2009 7:36:29 AM EDT

I take it this BDC is for a 223? If so any ideas on how it would work out for a 308? Or is there any plans for a 308 BDC version?

Thanks,

I'd like to know what the MOA is of each line. If we know that we could figure out the appropriate range of each line for whatever caliber we want.

Yep that would be good also.

So I decided to look at a ballistic chart for M885 out of a 20" barrel and try to guess what MoA each line represents. I could be way off since I have no idea what they actually calibrated this to, but if they used M885 at 3100 fps this should be relatively close.

––––|–––– = 0
..––-|––- = 1.5 MoA
...––|–– = 4.5 MoA
.....-|-..4 = 7 MoA

.....-|-..6 = 16 MoA

Next chance I get I'll bring a ruled piece of paper out to the range and measure, then we will know for sure.

Do you by chance have any update on this ballistic chart? /\ /\ /\ /

ETA: Clarified what update I was asking about.

Yeah a while back I did the best I could to verify what MOA each line was as 50 yards. As far as I was able to tell my measured angles were pretty much the same as my estimated ones.
