A 10% increase in pressure is a whole lot more then just 10% in strength.    ps saami specs for 45 is safe to shoot in all guns, 100+ year old models to new ones.  Personally 25k psi is a good testing pressure


I get that.... a 10% increase in pressure on a +P round would put you at 25,300....... still relatively low for a pistol round.

And still more than a 45acp case was designed for.
Tab, it just isn't the gun that needs to handle the pressure. That little brass thingy needs to hold it too....unless you actually like having the magazine blown out of your gun and the grips blown apart in your palms.  ::)
If Tab feels the need to load that hot, he bought the wrong gun and/or caliber.

If you load .45 ACP up to 9x19 pressures you get something like a .460 Rowland. That has nothing to do with if this gun will handle full pressure .45 loads.

Yes and the gun is the wrong color too!


Guys they just printed the FIRST gun! This additive manufacturing is a field where their goal is to be able to add atoms one at a time to get nano sized machines with moving parts. Pretty amazing technology. I like that they picked a 100 year old gun design to prototype.

TAB still isn't impressed. He did better than that last night in his garage.

THey picked the 1911 for 2 main reasons.   its in the public domain, 45 is low presure.   anything else was subjective.

It's not the gun that is the noteworthy item, it is the advances in the process that are outstanding...

Though the first metal gun made by a 3D printer might be worth  hanging on to.

TAB is, dare I say it , right this time .
A "proof load" is usually about double standard pressure .
Let me tell you, when you're sitting on the crapper and some one touches off a "proof" .45/70 round on the other side of the wall you have NO TROUBLE at all doing what you were trying to do !   :o
Another lesson from T/C arms.   ;D

Back on topic I would REALLY like to know what kind of accuracy they got from their "printed" barrel .
