I've heard these came out at cup, but I wasn't there to know...
These are new in the US but apparently have been out for a while in the UK b/c they have "body armour"
Here's my take on the matter:
-You can fire them with an eblade eye on... works great getting about 12-14 bps
-they will chrono at 275 so you get the speed you want
-can use indoors
-the ball is the fluffy part so they won't scratch your barrel
-they are a little light weight so they have trouble feeding with a revy with short impeller arms... work great in an egg
-too small so some shots flub while others are dead on
-also with a cocker they'll just fall out of the barrel you you
better be firing up!
-after 1 day of use, some balls outer velcro are starting to fall off, but i fixed them with super glue...
overall: 8.5 out of 10
