22lr and 5700 kestrel?

[Ruslow]

OK need to know if there is a way to get this to read correctly. MV is 1086fps. but when you go to ballisticsit has Rtrms 1160 yards and Rsub is 1413yards. which is way wrong. what gives. Wish it was that good!

What's your BC? Projectile OAL? Diameter? G1, G7? I'm betting one of these is off more than a little. Almost sounds like you're running meters per second, not fps.

 

[Ruslow]

BC is .105, oal is.5 dia .223 and the G1 profile.

 

[Kestrel Ballistics]

Looking into it, can you post your entire gun profile and what bullet you use?

Does it for me as well, made that observation about 2 firmware updates back. Transonic/subsonic threshholds are way off since the bullet starts out below the speed of sound.
