I gave his youtube channel name. But here is a link. The jager footage starts at 11:40. He also uses a modified Evanix Windy City and an American AirArms Slayer 35 cal.
My buddies have had theirs at least 4 years. Back when he was active on youtube Baxter Walton had a couple and had video of several 200+ yards shots on ground squirrels using NSA slugs.
When they was first introduced 5 years ago the bullet market was unable to keep with the power so they wasn't to much interest..but now with the power wave n slug shooting long range..and the viability of better n heavier bullets...I would like to collect all 5 calibers of the new bottle versions like the pics above if the mags are still is as deep as the older ones.
