Have you tried the .22 shorts? I don't know what kind of gun you're using but I do know that if you use a bolt action with remington c.b.'s (shorts) all you pretty much hear is the fire pin hitting the shell! No bang!

Be careful cutin those shells down. I've heard of barrels exploding because of that same treatment to the shell!

Good luck!!<img src=icon_smile_wink.gif border=0 align=middle>
