Ballistic Coefficient of CCI Subsonic 40 gr 22LR

[nmmi9100]

What's the BC of this stuff? CCI doesn't show it in their catalog and I need it for my ballistic calculator. Found all sorts of online BC info...none for CCI Subsonics though.

I was doing some fairly long range shooting with my CZ 452, Kodiak TL, and CCI Subsonics this afternoon while deer hunting. Watching deer in a nearby field...none were keepers...while shooting at a little birdy at 142 yards. I guessed the BC at 0.10 but apparently it's higher than that. I hit the bird after a few shots but it took about 2-3 minutes less than the predicted 20 MOA from my 25 yard zero per Exbal.

Deer never did get the wiser. But the bird learned the heard way...smoked him.

Viper762:

Yep. Found that one all over the web. But it doesn't show the BC for CCI Subsonic 40 gr HP. As you can see from the table, it shows a wide variation in BC for 40 grain 22 projectiles from 0.09 to 0.150.

Does anyone have specific data for the CCI Subsonic 40gr HP?

Thanks for the help. I found that one too and was surprised that almost every load under the sun was on there but the one I wanted....

According to Sierra Exterior Ballistics (don't have my iPod handy to check other programs I have), the CCI 40gr SS HPs have a BC of 0.118 for all velocity boundaries.

I use .115 for my dope.

Ida:

What kinda velocity are you getting? I'm running a CZ452 American 16". Thus far been too lazy to setup the 35P and chronograph the thing.

Set up your chrony and be sure to check your extreem spread.
