I was in Wallyworld today, after standing in the aisle researching the CB site
on my phone some of those black Crosman .25 gram BBs jumped in my cart.
I'll give them a try.
They are labeled 6mm, I have a 20cal / 5mm Sheridan pellet gun, I wonder...
maybe I need a 5.3mm sizing die, or stuff 'em in the muzzle with a ramrod?
Sorry that's off topic I guess!
