3D Printed Bullets.

[arakboss]

I am still working on plans for super low velocity pistol round recipes (possibly primer only loads). In another thread somebody suggested chopping up heat gun glue sticks for projectiles. Has anybody here tried 3D printing bullets?

How long until you try a 3D printed bullet muzzle loaded through your upper only firearm?

This guy tried them with so so results.

As a 3d printer- I would think using some PLA+ or PETG at 100% infill would work for primer only poppers.

My lastest idea is to use a coated .355 bullet cast bullet in my 38spl. That should reduce friction and allow me to get the bullet to exit the barrel with less powder?

I wonder how the lubricity is of those plastics compare to lubricity of powder coat? How much does the bullet weight play into the amount of powder required to have the bullet exit the barrel?

Wonder if you do a cast resin bullet instead, maybe with a central plug of some heavier material to add weight, if that would work better.

I wonder if a primer only load could send a 22 pellet out of 10 inch 223 barrel?


Edit: It appears the answer is yes. Time to add tin of 22 pellets to shopping list.

223 load using 22 cal pellet in a TC contender carbine? [Archive] - Cast Boolits

I bought the 223 carbine barrel with the intention of making cheap light loads for shooting instead of 22 LR which I was afraid was going to be unavailable or too expensive to shoot. Funny how much we will spend to save a little money isn't it? So yesterday I was contemplating a light load...

Hot glue squoze into a bullet mold makes good primer only rat loads.

Lot's of designs on the web. This one works in my .177's and can be scaled to .22. Also have a hollow .22 pellet I use in my Airforce Condor, use it hollow and it explodes on impact or print it 100% infill for a more solid impact. Can scale most designs to the caliber you need.

Here are some fancy new-fangled waxy-plastic bullets I picked up for almost nothing at a gun show.
