They have been out there for awhile now. How are they generally shooting for everybody?

What speed do they group the best at???

I shot some this weekend in my .25 Beeman Kodiak (aka Webley Patriot). Did not do well in that gun - they strung horizontally. Beeman FTS, JSB Exact King, and 43-gr Eun Jins did far better.

Tom, surprisingly, my initial impression is that the JSB Kings outshoot them in my .25 Mrod. I havent had much time to test, but that was my initial observation. Its a well made pellet and nice and shiny, but at 15yrds, I couldnt stack em or even cloverleaf em.

I need more time to test at short range vs long range, and then I can say for sure. But for now, the Kings are in my mags for pest elimination.

the JSB shot better in mine at an avg speed of 862...that said I am wondering how fast you were pushing them? I am thinking they(Benjamins) need to be pushed faster than the 830 or so mine is pushing them to stabilize the longer heavier pellet???

Hmmm...that could be Tom. I'll do some chrony measurements tonight a little later and fill you in. I was thinking too, that the Benjis might need more power to shoot straight.

I don't want it to stop shooting the JSBs if I crank the power up alil bit...trying to get a feel if what Cal is seeing is the norm

Mine likes the 31.2 grain Baracuda 1-holer @20yds.nt

Ok I did a little work...but remember, I have only a Hill hand pump so this is gonna take a while But this is an initial benchmark

I only had six pellets in the JSB clip when I started, and used a second clip for the Benjis.

The velocity was measured with a Combro Chronoscope, affixed to the end of the barrel shroud. Fill pressure started at 3000psi fill and ended at ~2000psi:


.25 JSB KING .25 Benji Domes
------------ ---------------
1) 897 7) 868
2) 900 8) 873
3) 902 9) 869
4) 901 10) 867
5) 905 11) 867
6) 905 12) 861

****NOTE****
The combro chronoscope affects accuracy because it is attached to the floating shroud, and I guess adds weight and allows the barrel to shift from its former position, and maybe even interacts with barrel harmonics???. Accuracy got better when the combro was removed. Same thing happened when I affixed a LED flashlight to the shroud a few weeks ago, and then removed it when my shots started hitting way lower than it had minutes beforehand. But the accuracy is still not acceptable. I'll be using my Shooting Chrony Beta Master for future velocity readings that involve accuracy vs velocity. Very unfortunate...because the combro is easier to work with.

DaveShooter, at what velocity are your Baracudas traveling to get those almighty one-holers, and what distance? (if you dont mind me asking)
