3d printed

[mattygunz]

I would be interested in buying some if you ever get it figured out!

Cool man! This is my first time doing this so im going to do some more research. Here's a better picture of what I'm thinking of. I can't find a pic of the 9mm sabots turned into a 45 cal slug.

*sorry for the horrible drawing I'm using my phone. This is kind of what I'm thinking they would look like or something along these lines. Maybe different shaped pellet skirt depending on how they move

I'll update when I figure something out, again this is my first time so It'll probably take me a bit

I get the gist of it, always tough to draw on phone screens. I give you a lot of credit, lots of R and R in your future lol

I am curious if anyone has tried using 3D printed pills or other 3d printed ammo. I am thinking about trying it for indoor target shooting.

I know that it is possible to design the ammo using various CAD programs and it should be able to be printed with various fills for weight and solidity. Using biodegradable materials I believe one might even be able to design and print a hunting grade ammo.

if anyone stumbles across this old post, I had the same idea and my second batch of twenty are printing right now, first batch I made at 7mm because that's what my 25cal FX pellets seemed to measure, they were too big, so I changed them to 6.35mm and I'll see what that gives me. time for better calipers. I'll try and remember to come back and share my results. looks like a good excuse to get a chrono. copied someone else and modeled one that you can snap a .177 bb into as well. I have high hopes for those ones.

Push a pellet, or better yet, a piece of lead shot (#2 or #3 buckshot) through your bore and measure the "lands" (which will be your barrel's groove diameter). Go no larger than that in your prints. A micrometer is the tool for this type of measurement, but good calipers will get you close.

I gave up on sabot ammo years ago. You can get impressive velocities, but always at the cost of significant loss of accuracy. It'll be interesting to hear how yours pan out.

so I haven't done any real scientific testing yet, but I've got a some what amazing "pellet sabot" a .177 BB snaps in nice and tight. with a atn x sight in slow motion they appear to be very impressive, fly very straight and seems faster then a lead pellet. i attribute that too a lead pellet being shiny I can see it better, but non the less i'd say it's definitely a viable option if the day ever comes when I can't get lead pellets. I've tried a domed PLA plus pellet and they are all over the paper, even appear to tumble slightly, likely I need to change my shape a bit. and I'd like to note, I don't see any noticable damage to my breach seal in either the blitz or the velox. something interesting happened with the velox. I have a printed LDC on the pistol and the same sabot like design that works great in the blitz, when tried in the velox, 9 out of ten BBs were left behind in the LDC, didn't blast out any of the inside of it, and the pellets came out and hit the paper, not with any real accuracy, but not horrible either. I find it odd. I'd expect that even if they break free from the hole I snapped them into, that they'd still fly out with the appearance as being one, at least for a bit until the drag of the skirt could slow the pellet and let the BB outrun it. in fear of destroying a 48hour printed LDC that marked my pause from experimenting with printed pellets. I'll likely revisit it after the snow flies and I'm confined to indoors. a chrono is on my must get list. overall I would without a doubt expect a printed sabot to have no problem taking out a rat or pigeon from the rifle. I need to weigh one of the sabots and get a chrono. it might be awhile but I'll definitely be back to this thread. I'll have to get on putting the sabot model on thigiverse so someone else play around with it. I always get a kick out of creating something from a roll of plastic string. My answer to almost every question is "oh I'll just print something"

As a competitive benchrest shooter, I would love anything that is more accurate than the currently available pellets. Ideally you could print a diablo pellet that was of a higher quality than is produced today. The weight would need to be the same or more in some calibers.

Are 3D printers available to the average man capable of the tolerances you would need? We are talking controlling to the 0.0001" e.g. 7.62mm (30cal) = 0.3000" but what shots best in my 30cal is 7.63mm which is 0.3004".

No, standard tolerance for FDM machines is around .005” in the X/Y axis. Some SLA, SLS, and MJF machines are capable of better but the consistency in weight, or lack of weight for the projectile would cause issues I would imagine. Always good to experiment though.
