They look amazing, they have a crushing impact, but they go in somewhat stiffly and need to be gently tapped in, I can't press them in with my finger.

I think the JSB brand speaks for itself. I prefer to shoot with Jumbos (I find them more versatile), but this is pretty cool too. It's just the longer ranges and more powerful air rifles that suit them…

Quality as always

Not suitable for weaker air rifles

I was very excited about this product but ended up disappointed. The slug ammunition falls through the barrel, and I have a new air rifle. I have never had this happen with any other type of ammo.
