I think it would be best to perfect your lifting, timing and
especially your fireproofingof your launched projectiles(whether they
are flare, smoke, whistle or re****t devces). You may save your 37mm
launcher, the AR it may be attached to and also your eyes and ears.
I'm only saying this because you said you're pretty new to this.
When the late Barry Rothman was fulfilling a contract with Colt to
develop smaller 12 gauge "bird bomb" projectliles years ago, he and
his brother destroyed a number of Win. model 12 pumps and other
shotguns. For extremely reliable timings, the military has used
compressed fuse train pellets (basically just a hard pressed
cylindrical "star" of various compositions) This is ignited by the
smokeless propellant charge and provides a precise delay before
passing fire to the projectile's contents. Its reliabilitiy is good
enough for frag./ shock hand grenades where error is not an option.
I would learn the basic techniques using a spun or rammed (spolette)
fuse to time small shells projected by a seperate launcher (mortar)
using black powder before trying something held so closely to your
face for firing. The higher pressures generated with a tightly sealed
charge of nitro powders will take some careful exprimentation too.
Good luck and be safe!
