It works just fine in the Estes PSII 3" tube. Do not know about the BMS T-300. I have read that it is the same tubing, but no personal experience.

Don't you hate it when "experts" hint and do not provide information?

https://www.erockets.biz/body-tube-sizes/

https://www.balsamachining.com/CATALOG1.asp

Just google for semroc body tubes sizes or balsa machining tube sizes...
