I have a pair of CO2 BB pistols that I use for strong hand / weak hand shooting practice.
They work great, but reloading the magazines is a pain.
I made a speed loader in about 10 minutes. It is similar to a primer tube, if you are a hand loader.
I started with a BIC ball point. Pull the ink tube our and pull off the cap at the top. The pen plastic is brittle, so be careful. Otherwise it will shatter.
You will find that the bore and opening at the top is quite big and BBs will easily fit inside.
The nib end has to be modified to be the "pick-up" end of the loader. It has a quarter inch section that tapers down the bore to less then BB size. The objective is to cut this end back to the point where the bore is just slightly smaller than a BB, so that when the tube is pushed down on a BB it will pop past the constriction, into the tube.
I used a grinder wheel on my Dremel to trim back the nib end in a series of small steps. I screwed up and cut back too far and had a straight tube with a bore larger than a BB.
A lighter was used to briefly heat one end. This made a little fat ring around the end, and the result was the slight constriction.
By pushing down on BBs, they pop into the tube. Then I pull back the loading gate on the magazine and dump the tube of BBs in. This is an almost instant fill. It take a bit of hand manipulation to figure out how to hold everything.
