Where can I get the ballistic coefficient for pellets?

[crittahitta]

Im trying to figure out the chairgun app on my phone. Not going well but in time I'm sure i will figure it out. But I need the BC for a few different pellets to input in the program. I could swear there was a website or something with all the pellets bc somewhere. The pellets I need immediately are the....
.25 Cal JSB Diablo King heavy 33.94 grain (NOT MK11)
.25 Cal Grizzly 31 grain
.25 Cal Barracuda Hunter (HP) 27 grain ---- (NOT EXTREME)

Any help would be appreciated. Im going upstate in a few days to try the golfball challenge.

Dead link oldspook! CC made the database of pellets a paid feature so they probably removed access?

Yeah Thurmond it is dead. I did a little barney googling and found the list but my pellets were not listed. This is the page i found. I will link it and see if it works.

Thanks old spook. I will keep searching. The one I really really want is the .25 JSB Diablo King Heavy 33.95 grain.

Weird. My link is exactly the same and it works for me but yours doesn't.

Well. I just emailed JSB directly asking for the BC. Now lets see if they respond.

If you don't have a chronograph then you'll have to search. There is a method to getting it as each pellet will differ depending on any given air rifle shot from. One size does not fit all. I've been too lazy to do it. Something about shooting near the muzzle and then taking another shot further out and using the difference in speed to figure out your BC. What I did do is take my fps near the muzzle and input my other info into Strelok Pro and was off barely at 100yrds but pretty well off at 200yrds when I took my shot.

As you'll see in my 200 yard thread post I played around with my settings that matched what I witnessed through my scope and came up with .041 being my particular BC. That's a half-assed answer but take it or leave it. And by the way, if you win the drawing, you owe me. lol.

Yes, I used King DiabOLO 33.95's, not MKII's. The original.

Forgot to mention I'm shooting them at 827fps and chrony was set 2' in front of muzzle.

Straight Shooters has a pretty good list I have used often: http://www.straightshooters.com/pellet-comparison.html - unfortunately it doesn't include B.C,

If you go to some of their rifles like the FX Wildcat and hit the tab for Our Take they do a review with a series of pellets and include the B.C... I knew that I had seen it somewhere.

Thanks guys. I appreciate it. From all my searching i put in .050 for the BC into chair gun. Pretty close to my testing. I will check those sights. 
And bizill i do have a crony but i have shot it too many times at 2 feet and don't trust myself at 50 or 100 yards!! LOL And for your help if I win i will take a picture of me holding the gun and smiling (framed of course) and send it to you.

Thanks skohl they didn't have the 33.95 grain though. But i will use that for other pellets.

 

[crittahitta]

Thanks 18.13 thats a pretty cool page.

Well. I don't want to drag this on too long but i am learning a lot. JSB answered me back in less than 24 hours. Pretty impressive! They said they don't currently release the BC of their pellets due to the tremendous amount of guns that shoot them. BUT... they are working on a new website that will be out soon with the (approx) BC values of their pellets. They didn't get into if it was with specific guns or not. So I will keep checking and post it if it ever gets published.
