Can anyone supply this info? I asked JTS via email and they don't respond. (as usual with them)
TIA

Ballistic coefficient and other ballistic data for JTS .30 Cal 45.06 grain?
- Thread starter Sky King
- Start date
I'd love to find out as well.
However, as the designer of these pellets is aware of the great importance of a high BC, I'm pretty confident that his design reaches the BC of the competing JSB dome (44.75gr).
I just recently researched the BC of that JSB pellet, and found the following:
0.042¹
0.037²
0.042³
0.046⁴

Keep us updated,

.30 Hades BC
I've been playing with the. 30 Hades this week and really had to lower my expected BC ( someone suggested. 04 ) down to. 03 to get it to jive with chairgun. Last night I watched a video of shooter1721 and he had a m/v of 1014 and 749 at 50 which works out to a BC of. 028 Looks to be around...

If this will help, I have a Fx true ballistic chronograph and it can figure BCs and for my Fx impact 30 cal. it said that using JTS dead center 45.06 grain pellets I have a BC of .053 at a velocity of 860. Of course this could be different out of some other type of air gun. Hope this gives you a starting place.
