The most powerful slugs i've tested so far... the new JSB knockout mk11 mk2

Here i test out the new mk11 jsb ko slugs through a couple of field target air rifles, my XTi50 and Anschutz 9015 both sub 12 .177 calibre
i also test them in the airmaks katran, alongside some zan slugs aswell
they have a very unusual shape and make a lot more power than previous slugs ive tested on the channel, they are only around 20 fps slower than a jsb heavy so must be pretty efficient and make good power
the scopes are the optisan cp and the huge discovery ed prs 5-25x56
they are surprisingly accurate especially as none of the rifles are optimised for slug ammo
in the future i will prepare a couple of new barrel blanks to suit the slugs,these show some real potential!
the zan slugs still prove to be particularly accurate in the sub12 rifles.
