Oh how I love surprises! Gonna have to break out the EDgun Leshiy 1 with the .177 350mm barrel. 

I was going to say those look like nsa .177. These are the only projectiles that don't really form "groups" for me at all and are just scattering all over the place. Missed an 8 1/2 x 11 sheet of paper at 11m shooting these out of an airforce rifle.
