Intresting chono results

[wildman510]

Shot the jsb jumbos 25gr out of the 22marauder they are very accurate shooting at 700fps to 695fps a little work im sure I can push them closer to 800 Im gonna wait till I run out of barracuda match to retune gun.  I also tried the jsb exacts 10.34 .177 in my R1 they are just as accurate as the barracudas.  Chrono results changed my mind about using them they shoot between 801 and 793 fps. Barracudas with the 4.52 head 812 little to no deviation.  The 34 shot the jsbs also very accurate but shot a very small vertical string chrono showed why 833 to 810 difference.  Barracudas win again 843fps little to no deviation.
