Punch out the brass
propellant case from the nylon case using a long 1/4 in punch and hammer.
Deprime the brass case.
Reprime the brass case
with a small pistol primer. DO NOT use small rifle primer, they
are not sensitive enough and may not fire when struck by the relatively weak
firing pins of some 37MM launchers.
Fill the brass case with a fast burning pistol powder. The
type of powder used will determine how far the 37MM projectile will travel.
Using 9 grains of either Bullseye or Winchester 231 will propel a 5-5½ ounce
projectile from 160 to 200 yards. For longer range, use 14.0 grains of Accurate
#5.
Sharpen the mouth of a
38 special or 357 magnum case with a deburring tool. Use the case as a cookie
cutter to cut wads out of 3X5 cards or a similar paper. Place the card wad over
the mouth of the brass propellant case and seat it over the powder with a 1/4 in
flat end punch.
Seal the card wad with
Elmers glue or fingernail polish. Use sparingly and allow to dry.
Reinstall the brass case into the nylon case. A method that
works well is to use a single stage reloading press. Turn the nylon case upside
down on the ram. Install a reloading die in the press that the brass case
will not fit into and press the brass case into the nylon case.
For use in 37MM launchers, before reinstalling the brass case, chuck nylon case up in a lathe and remove approx. .100" overall from the outside of the case walls. Smooth with 150 grit sandpaper and final fit to your launcher. It should be a smooth but snug fit. This may seem like very thin walls, but will hold up to repeated reloading.
