I use resin molded plastic, and make my own 576 carriers, that can be loaded with flechettes or #4 buckshot. I'm working on a sabot type carrier for flechettes at the present time, and have designed a few rounds for ALS Technologies. The casings made by CTS, ALS, MK Ballistic systems, and Def Tec can be easily reloaded, as well as the M-212 casings. As far as the HE type rounds, the casings can't be reloaded, but you can register a 407, and make it into a 406 HE, as long as you can produce RDX. Destiny Densley (Small Arms Review author on 40mm articles) has done just that. I prefer to reload the resin molded rounds, where I can produce rounds that look like and function like the real military pyrotechnic rounds.
It's a hobby...
Oh, and it's 2.4 -3 meters for the 381 and 382, 13.71 meters for the 433, to 14 meters for the 406 and 397 OCTOL.

I thought that the military 40mm rounds used a "high-low" pressure system with a small chamber inside the case that contained the initial ignition and allowed the pressure to build till it ruptured ports and vented into the main body of the case, dropping the pressure significantly?
Since the ports are no longer sealed, how do you handle the initial ignition of the propellant and the lack of controlled venting into the main body of the cartridge? Does the chamber pressure seem to be stable?
