No there isn't, the first "let freedom ring with the shotgun blast" line is from Davidian and the rest of the vid is RATM :wink:

I alwaus wondered, the previous line should read "shot" or "slug", rather than "bullet" :roll: </pedant>

i might try a blowgun again but i will need to cut down on my pilot volume for it to work, smaller ID barrel?? why that would mean id be stuck with shooting small stuff, though im mihgt get interchangable barrels..... the figure of 555fps was taken by recording the sound of the gun shooting and tim ing the time to impact from the shot, and using some simple maths, it is by no means accurate but it gives a rough idea.

yes high fps is good, but thats mostly down to the smaller projectile.....
i belive that the potato comming out of this barrel has soooo much more KE than the 22mm version, and there is a wider vaiaty of ammo available for 28mm copper, such as C size batterys :P in ggdt it says that i should be getting 140m/s with the old setup 8) which isnt too far off 555fps
