Brasscasing spotted .22LR tracers being sold at Cabela’s ($109.99 for 250). I had no idea these were made.
I found a video of .22 Tracers being fired at flammable gas filled balloons:
Looks like fun. If I had some where to shoot tracers and they came in smaller quantities I would buy some.
UPDATE: ZerCool found that Cheaper Than Dirt are selling them in quantities of 50.
