Hmm I never heard that. I know my buddy got quoted a case of their rifle grenades. They all take 12ga blanks for an impact charge.
I'll have to ask message Matt and ask him about it. I was thinking of using their launch charge kits anyway |

Well, I just sent a rough body drawing for some information. If they are reasonable, I would try to do something with standard threads so that people could DIY fuses and fin assemblies.

Just like everything else fun... 1500 pcs would come out to $35 ea for the bodies, add machining and fins/fuses. I would think it would be pretty easy to stay under $100/Rd cost. But I don't think the community is big enough to support 1500 rounds. I should be done with my tube this month. Then hopefully I can start experimenting with ammo. |

I'm going to use rolling paper to make my increment charges for my 60mm, in the same dimensions as the cellulose ones the military used. They should burn rapidly and completely, and leave no residue. Haven't done it yet, though. It would not be weatherproof, but I think there may be some coatings that would fix that.
The problem with using some materials is that if it leaves residue in the bore, you could have problems with a 'hung' round... that gets stuck in the bore when you drop it. If you do not use the correct procedure to clear it, you can hurt yourself seriously. Also, it would deadline the mortar until you thoroughly cleaned it. I haven't seen any 3d printed materials that I would consider using. |

I called H&S about getting a tube made for the Italian 81mm. They quoted $3000 for a one-off tube. They said their material and shop costs are high these days compared to previous runs of tubes.
Here's to hoping more people with Italian 81s want to go in on a batch of tubes, hopefully that would bring the price down. |

I just ordered one of the kits myself. I'm a shooter more than a historical collector, so I'll probably just weld and sleeve the tube. Its not something I'm holding up to my shoulder and I won't shoot 1/4 of the power of original loads. I like seeing where they hit. |

I see the 81 tubes on their website, but no way to add to cart and no price. I also can't find their phone number on the website, do you have it? A more general question, what are yall using for mortar sights? European sights seem to be hard to come by, the Italian sight being especially rare. I'm pretty sure the modello 35 will accept a U.S. sight with the same dovetail. M4 collimator sights would be closest to historically correct. It should accept an M34 mortar sight as well. The M34 is a telescopic sight. Does anyone here have an M4 mortar sight? I'd like to know what the sight picture looks like and how the collimator works compared to the telescopic mortar sights I'm more familiar with. |

Considering that I'll never shoot anything but line-of-sight, I'm mounting a cheap NOS surplus m15 rifle grenade sight to a barrel clamp for my 60mm. This is what the paratroopers did in ww2 I believe. It even has a built in bubble level and you can set the angle of the sight.
For the 81mm I'll probably do something similar unless I find a great deal on a proper sight. But I think I can do pretty well once I get good DOPE |

Finally got to shoot mine, unfortunately I ended up having a bunch of misfires, guess about 50%. Not sure what it was, so have to figure that out. Did about three sets of load charges with the tube at 45 degrees. The base line charge went about 70ish yards, second went about 90ish, and finally third went 150yards. Spread between shells were about 3 feet.
32 gr = 70ish yards 39 gr = 90ish yards 45gr = 150yards.  Paint isn't gonna last tho lol |

What rounds were you using? When we were shooting my buddy's with the hollow polish ammo, they would take a lot longer than I was used to before it hit the firing pin. Maybe the new barrel bore is even tighter and you need a heavier round. Also check your firing pin protrusion as I believe it's adjustable on these. We were also shooting a higher angle to get about 100yds.
Here is a video of me shooting it. You can see me pull away quickly and then hesitate as it took much longer than I expected. The other mortars go off quick https://youtube.com/shorts/oJ4QMklNkj8?si=6kLMY4b6fvcPIo8e |

I didn't get to try the fuze set up, after reloading launch charges and then dealing with misfires and unloading the shells, I just completely forgot, then remembered at the end, but by that time the sun was already setting and I didn't feel like loading up another launch charge lol.
Of note, I think once you have a misfire that launch charge is done for. The brass gets concaved that the firing pin won't hit the primer properly a second time, I think. As for the angle, I did try setting it up at a higher angle, but still had a misfire. BUT I used one of the shells that already had a misfire on the launch charge. So that could've been the issue. This range session was kind of a cluster fuck but a learning experience lol, forgetting that the safety was on only to try and launch a shell but it not going off, so gotta unload the tube and remember the safety again then reset up everything lol. Planning on working some more load data to get the shells at 200yds next weekend again. My guess is that 50 gr of powder should get me to 200yds. Then I'll get to work on loading some hotter charges to get the shells back out to 200yds with a higher angle on the tube. |

The other mortars go off quick The solid black and white French rounds that bowman had for sale. I emptied out the tar and sand. I was also thinking that maybe they were too light coupled with the barrel angle, which is what led to the misfires. The firing pin is about all the way it'll go without interfering with the safety. But I'll try one of the newer ones next time and see what happens. |

Well, I think I found the issue with the misfires, turns out surface rust was starting to developed towards the end of the tube and cup so that would've explained the rounds slowing down creating misfires. Im an idiot lol
So note to self, gotta clean and scrub the barrel throughly with gun oil a day before use. Unfortunately I cleaned it about 3 weeks ago and we just had a freaking heat wave this week with high humidity, so that didn't help. Also installed the aftermarket firing pin which protrudes a little more than the factory one, so hope it helps. Round 2 this weekend. |

Finally finished pressing (beating) my sleeve on the tube. It's a good interference fit, I had to alternate a propane torch and canned air (liquid) to get it in place. I'll take it to get welded along with the holes from the bore obstruction. After cutting it down it's right at 50" which is the same length as the US M252.
It also looks like the fuse threads are 1.5-12 UNF, so I'm going to order a tap to clean up the threads on my practice rounds. |
