strelok users / crosman 10.5g domes / two listings for them in strelok db -- ??

I'm re-purposing a .177 m-rod that I have. I got a box of these that showed up today and I just got back in from shooting some of them at targets at different distances ( 25 yd zero ). Now home I wanted to key some numbers into strelok but when I looked up the pellet in the dB it has two of them in there - both the same weight but different BC values. How do I know which one to select? I posted this same question in the strelok fb group that Igor is (actually) quite active in - but figured I'd ask in here too in case some of you might already know and see this before I get an answer from fb.

@yo! - do you happen to know? I bought 'em based on your recommendation . . . ;-)

 
Come on Yo. A man of your statue need to rethink the ballistics program thing. With your collection , the endless comparisons could be mine boggling. I use your method also but Strelok pro is sooo much fun and accurate I would now be lost without it. I would bet if you tried it,(really tried it) you would love it. The reticle feature alone is worth the price. Just saying.

Try a bc of .023/.025 . The bc will change depending on speed. You are working with average anyway.

You should see my guns with Chinese scopes Just old fashioned holdover Kentucky windage. As long as I know the speed at the muzzle I can pretty much make a reliable guesstimate out to 125 yards. Pretty familiar with drop and caliber characteristics with most accurate ammo.
