Axe Posted February 2, 2006 Report Share Posted February 2, 2006 Does anyone know the correct ballistic coefficient for this round? I have looked on both Winchester and Olin websites and the product W22SUB doesnt marry up to the ammo that we have in this country. Quote Link to comment Share on other sites More sharing options...
The Sniper Posted February 2, 2006 Report Share Posted February 2, 2006 Axe, I can't find it on the net either. But using Winchesters velocities and foot poundage I have back-calculated the ballistic coefficient and it it is spot on at 0.11. Hope this helps.

Axe Posted February 2, 2006 Author Report Share Posted February 2, 2006 Thanks Sniper, but which velocity did you use as the only one I found that was near accurate to the actuall cartridge was 1075fps at the muzzle. Quote Link to comment Share on other sites More sharing options...
The Sniper Posted February 2, 2006 Report Share Posted February 2, 2006 Thats the one I used Axe. I did it on the JBM site and they calculate the velocity over the chronograph at 10 feet, so I put in a velocity of 1065 fps. I got the velocity from the Oz site of Winchester. :thumbs: Quote Link to comment Share on other sites More sharing options...
