Good morning, I tried 45g Zan slugs on my Vulcan 3 500 .30, but I got terrible results. However, with the JSB Diablo Exact 44g it was exceptional. I don't understand why the slugs aren't accurate on this air rifle.
I have had several jams with the BinTac T9, I have found that by securing the magazine (I used a temporary electrical cable tie) you never get any more jams.
