Ballistic Coefficient for JTS Pellets

The problem with pellets at higher speeds is not that they become unstable, it is that they become gyroscopically too stable allowing yaw to build up, as they are unable to turn to follow the trajectory and thus give larger group sizes. Couple this with the rapid loss in forward speed giving greater stability growth, and then you have problems.
Based on MY OWN experience with JTS: Travis is always full of baloney. He makes promises that he never keeps, like ballistic data for the pellets. I usually find that the JTS pallets are more consistent than JSB but I can never get ballistics data from them. Same issue with JTS Airacuda Max. Lets of problems and complete denial from Travel et al. This has been MY experience and my own opinion.
 
Numbers are great.....I suppose. But never forget the target tells the tale.


Yupp.

Though, sometimes....
the tale at the target does not tell about how right the BC numbers are — but instead tells about harmonic oscillations (barrel whip) of straw barrels.

And barrel whip can make good BC data look erroneous....


So.... — if the tale your target tells is an accusation that your BC numbers are off — you might want to shoot with a different velocity (50fps more or less(?)) to check if the BC still is off. Or if the barrel just whipped the other way due to a different velocity (so that now your BC is either right on, or still off, but in the opposite direction as before).

Thanks,. I am familiar with all of that BUT I can't get any ballistic data from JTS


With as many LabRadars as were sold to airgunners — I'd think someone would put them through their ballistic paces!!

I
would love to do the BC testing, but where I shoot (and live) currently, they have a hard time just keeping JSB and H&N in stock. 😔 No chance of getting more pellet brands imported.

In .22 caliber for AEA 21.9 and JTS 22.07.
They are NOT the same although they appear similar.
In recent testing with an older FX Slug A liner 700mm at 990 fps.
AEA BC 0.063 GA
JTS BC 0.059 GA.
Both very accurate at 100 yards but I’d give the nod to the AEA. The JTS flew about 10 to 15 fps faster than the AEA with the same tune, which tells me the AEA head diameter is slightly larger than the JTS.
FYI, both the AEA and JTS copies of the 25.4 grain JSB RD Monsters are not nearly as accurate as their lighter brothers. Funny enough, the BC of the 25.4 grain versions is less than the 22 grain pellets.

THANK U SO MUCH for this info! JTS makes great pellets, not-so-great PCPs and they have, IMHO, VERY HORRIBLE support. IMHO, just BAD PEOPLE. That has been my experience over about 5 years. In MY own experience, they "lie like a rug". I tried calling them today, this afternoon and the phone just rang and no one answered, (could be that maybe they knew it was me calling), not even the "auto attendant". But, like I said, their pellets come through very clean and nary a deformed skirt. Very weight consistent.

JTS in my FX Dynamic Compact .22, the JTS 22.07 werer a little more accurate than AEA 18.3; the JTS were exactly one clean hole at 30m. I'll shoot the 21.9 tomorrow and let you folks know. I have it all on video from my ThermNight scope, so if anyone doesn't believe me, I'll post the video. It was getting dark here at about 4:15pm ET and I didn't have illumination on in my ThermNight, just too lazy, so I gave up when I NEED the illuminator.

"Tomorrow is another day" as they say.
