Reloading 40mm Chalk Rounds ⋆ LooseRounds.com

[ad_1]

Back when I ordered my M203, chalk rounds had been about $five shipped. When I got it, it took me a bit but I managed to obtain a crate at $7 shipped. Nonetheless it is finding tougher and tougher to uncover these rounds. So, like numerous shooters shooting pricey ammo, I am going to reload.

Chalk rounds are fairly uncomplicated. A blank, a case, a pusher, a cone, and chalk.

Very first, I have to punch out the old blank. On some of these circumstances, the blank came out very easily. Other folks not so substantially. There is some sort of black sealant utilizes on these circumstances that produced it kinda hard to get out.

At initial I employed a brass punch. Following that failed, a handful of minutes on the lathe got me a stainless steel punch. The narrow diameter is about .01 smaller sized than a quarter inch. I began working with a press to punch out the blanks.

Possibly I shouldn’t get in touch with this a blank. It could technically be an “impulse charge”, but that is semantics. I’ll retain these spent “impulse charges” as they can individually be reloaded. I purchased mine from Gunbroker.

The replacement blanks can very easily be pressed into the case. I didn’t bother with adding any new sealant for these reloads.

At the moment I am lacking cones. I am questioning if I 3d print if these would hold up to the firing.

Reloading the chalk rounds is quite quick. Obtaining the elements is the hardest portion.
