An bought an LMT 37 mm 203 and while looking for reloading info an supplies I came across Bengles Bullets 37mm Reusable Case for LMT M203 .They stated that these are only for LMT launchers and I'm curious as to why LMT only. Thanks |

Sgt Fish was answering your “why only LMT” question. They might possibly fit in your launcher, but perhaps not. 37mm launchers from different manufacturers have different chamber internal dimensions. They can range from 36mm to 39mm. No way to tell until you measure them. Def Tec manufactured their launchers to fit Def Tec ammunition. CTS, same. Federal, same. Some cases can be used in different launchers, some cannot. Rim thickness differs as well. Some accept the thin rims like the M118 40mm case, some only accept thick rims like def Tec crowd control ammo. They are all marked as 37mm, but most are not. Hope this helps, GROG |

As I was looking around for reloadable shells, I'm wanting to load smokeless, and saw different sites sold them and none that I found specified LMT only. Also watched various videos where they were using shells that were longer than 4 inches that the one from Bengles Bullets sells. Grog I'm just a noob and have lots of learning to do. I did order your thumb drive version. And yes this did help can't wait to receive my order. Thanks |
