Before you purchase, you may want to check with your local regulations. Some jurisdictions ban the use of tracers, and some even ban the possession of them.
I've shot tracers in .45 acp, .38 Special, 5.56, .308 and .30-06. They will set fires in dry brush, etc., so be careful. The .45 acp and .38 Special tracers made big circles in the sky, as they weren't very stable. Everything I shot was GI issue, but I've never really figured out why they made tracers in .38 Special?............
Hope this helps.
