When i was in, we called all practice rounds TPT. It's easier to use than, 40mm M781, 40 mm Practice Cartridge Low Velocity (makes my fingers tired!)

Rekraps Posted June 22, 2023 Author Report Share Posted June 22, 2023 Shot a few more of the sponge rounds the other day. Very easy on the shoulder, 1/2 load is the way to go. You should hear those things when they hit a tree! Link to comment Share on other sites More sharing options...
Rekraps Posted June 28, 2023 Author Report Share Posted June 28, 2023 Ordered two more cases.... great deal at $165 per 25! Link to comment Share on other sites More sharing options...
Rekraps Posted July 1, 2023 Author Report Share Posted July 1, 2023 If you guys can get your hands on the sponge rounds, they are a great option compared to full load chalk rounds. I have both now and even though there are no ready components to reload the sponge rounds, they are a ton a fun to shoot and safer. Link to comment Share on other sites More sharing options...
BPinFL Posted July 4, 2023 Report Share Posted July 4, 2023 Have you tried Reloadable Shells/ Pace Ind? Been using the 37mm variant for years, now moving up to 40mm. Lots of options, I highly recommend them! Happy Independence Day to the Board! BP Link to comment Share on other sites More sharing options...

Eastblock Arms has plenty of options for both M781 and sponge rounds. The great thing about sponge rounds is that they are entirely reloadable as long as you recover the sponge tip. I just shot two today and was able to quickly reinsert the sponge tip to the casing and then insert another .38 spl 1/2 load blank. Link to comment Share on other sites More sharing options...

Rekraps Posted August 8, 2023 Author Report Share Posted August 8, 2023 So, if you want a bit more "quiet" off your back deck, use 1/2 load .38 special blanks. It'll still go out nicely, but for only short ranges..... Link to comment Share on other sites More sharing options...

Homemadeammo42 Posted August 12, 2023 Report Share Posted August 12, 2023 On 12/27/2022 at 10:31 AM, Rekraps said: Guys, for those of you who have, for personal use only, a number of M781 TPT (Inert) Chalk rounds for the M79 or M203, you know that the rounds themselves are getting scarce, but even more so the impulse charges (.38 Blanks). Scouting the web, the cost, if you can find them can be as high as $3 per blank which is ridiculous. So, save your plastic casings, order new production pushers and chalk heads and buy impulse blanks. But where? I found a company called Boland Production Supply out of Winter Haven FL and they manufacture a variety of blanks and other interesting production items for movies, and the US Government etc. I spoke with Mal Boland personally and he shipped me a sample .38 Short, full load, six point rose crimped to test in the M79. Brand new production, shiny and perfect. The blank fit into the plastic M781 shell casing and seated perfectly with no effort at all, and it was just a smidgen, and i mean a smidgen loose. The crimped tip did not extend beyond the initial expansion chamber. In order to make sure the blank would not accidently fall out or come loose, I used a drop of Elmer's Glue around the brass case and within minutes it was seated firmly. The unit performed as intended. Removing the expended blank was easy using a jig i made with a 2x4. I drilled a 2.78 inch hole .75 inches deep, with a .5 inch hole centered through the rest of the 2x4. The casing is placed in the jig and the expended blank is tapped out of the plastic shell casing with a flat punch. Ready to use again. Mat is a pleasure to deal with and actually answers the phone. Blanks (.38 shorts/full load/crimped) are $21.50 per 50. Good value, great quality. For the record, do not fully assemble any M781 rounds (with blanks in them) and store the rounds. That seems to fall afoul of ATF guidelines. Instead, keep & store the inert chalk rounds (or components) separate from the blanks. Yes I paid for my order...... I wanted to thank you for posting this. Im just getting into the 40mm realm and was struggling to find a consistent way to launch these. This was exactly what I needed! Do you have any consistent source for pushers? Link to comment Share on other sites More sharing options...

Yes, Easternblocarms has the components. I save the plastic shell cases and order the pushers and chalk cap assemblies from them, $157 for 25. A touch of Elmers glue and I have assembled rounds. I made a jig to remove the spent blanks so I can reuse the casings. Link to comment Share on other sites More sharing options...

Rekraps Posted August 25, 2023 Author Report Share Posted August 25, 2023 Shot a few full weight practice chalk rounds using 1/2 load .38 Blanks and the performance is as you would expect. Full load .38 special blanks push the round exactly like the real one, and believe me they move. 1/2 load .38 special blanks and much quieter and the round struggles to go 150 feet, which is just perfect for my backyard. You can watch the round fly! Now, I'll still shoot full load as it wallops the trees! Link to comment Share on other sites More sharing options...

I use Boland Productions .38 Special 1/2 and full load "Shorts". A regular .38 special shell would not fit into the recess. Much more affordable. If you call them Mr. Boland himself will help you. He did for me. Link to comment Share on other sites More sharing options...
inertord Posted August 26, 2023 Report Share Posted August 26, 2023 I missed the part that your blanks are commercial movie type production being called .38 special and not mil spec M781 charges. Link to comment Share on other sites More sharing options...

Rekraps Posted August 29, 2023 Author Report Share Posted August 29, 2023 So now I'm thinking for around the home shooting (i.e. backyard) it's probably safest to use 1/2 load .38 special shorts. It's still fun but the round will not travel too far in case of a mistake. 150 ft or so with good accuracy. Link to comment Share on other sites More sharing options...
Rekraps Posted September 30, 2023 Author Report Share Posted September 30, 2023 Okay, now that I have an ample supply of components, assembling your own rounds cost about $4.25 per. Eastern Block Arms sells the parts, order the chalk powder from Amazon and use Elmers glue to seal the windscreen and case. You can reuse the pushers (clean up with wire where and soapy water), cases (wash with soapy water). Reusing the pushers and cases brings reload costs down to $2.00. Easy Peasy!
