Item Code: JSB.22-ExactRS [PY-P-719]
|Head Size||5.52 mm|
Things I liked: Accuracy.
Things I would have changed: Packaging allows very thin skirts to get bent. Easy enough to true up with the tip of another pellet.
What others should know: I'm shooting 1.3 MOA groups from a tuned D48 with these pellets. At 39 yards I just held five under a dime.
Things I liked: Average accuracy. Nothing else really.
Things I would have changed: The whole pellet.
What others should know: These pellets are average in the accuracy dept. However, the velocities with these pellets are SLOWER according to my ProChrono than any 14.3 pellet I tested. In fact, the 16gr H&N Hornets clocked 22 fps faster than these 13.43gr "Rapid Speed" pellets in my .22 Trail NP. Got similar results in my Hatsan 85 Sniper. Out of seven different pellets shot and chronied, these yielded the LOWEST FPE. 12.45FPE in my .22 Trail and only 16.9FPE in my .22 85 which produces 19+FPE with almost every other pellet. Very soft lead, slow velocity and low FPE leave me with a tin full of pellets I now use to break in my air rifles. I have tried many different JSBs and have not been as impressed as some. The 33.95 MkII's shoot very well in my .25cal Hatsan 155, and the 81.02 JSBs are boringly accurate in my .35 Carnivore, but these did not live up to what I expected.
Things I liked: Shot from Benjamin Discovery the accuracy was good, 500 count tin, well packaged.
Things I would have changed: About 1/3 of the pellets had damaged skirts. I "trued" damaged skirts using a ball point pin, otherwise accuracy suffered. PA does an excellent job with packaging, however, the skirts on these particular pellets are very thin which probably makes them more prone to getting bent during shipping/handling. They may be just the ticket at lower velocities than my air rifle shoots but I wouldn't recommend them for a Disco.
What others should know: I performed a dual test comparison between the JSB RS 13.43 & the Crossman Premier 14.34 HP. the average velocity of the JSB's was 846 fps compared to 897 fps for the Crossman's ( comparing two 12 shot groups from max fill). The Crossman's also gave me better accuracy and higher foot pound of energy, plus they are $5 less per tin of 500.. If you on a .22 Disco and haven;t tried the JSB 18.13 Domes, definitively give them a try. They give me the best accuracy in my rifle, average velocity is 790 fps for a 15 hot string. That's a little over 25lb of foot energy at the muzzle.
what is the ballistic coefficient of this item?
