416 Hush Puppy

You posted while I was reading the thread/replying so I didn't see yours till after mine went up. I was responding to rally guy who was waxing melancholy about ARs being restricted.are you talking to me?
if not, do quote your reply
This would be an interesting cartridge in a short action bolt gun. Even unsuppressed it would make a curious "whisper" load.
A friend sent this to me. I think I am in love. :yes
If you like big projectiles, you’ll love the .416 Hush Puppy round by AM-TAC Precision. I had the chance to talk with Damon, the designer of the cartridge.
GREAT GOOGLY MOOGLY. My dorm room was smaller than these projos!
The .416 Hush Puppy is based on a .50 Action Express cartridge and fits a 450 grain Hornady .416 bullet. The round is meant to be fired suppressed, and according to Damon has an extremely flat trajectory.
AM-TAC will sell a barreled AR upper in a 10.5″, 14.5″ (pinned to 16″) and 16″ barrel length. The upper uses a 7.62×39 BCG that is made out of a durable stainless steel instead of the usual carpenter steel entry-level AR bolts are made out of.
Damon told me to only use USGI mags, which are inexpensive and plentiful, due to the lack of a rib found in other AR mags such as those made by Magpul. A 30-round 5.56 mag will hold 10 .416 rounds, and a 20-round AR mag will hold 7 .416 rounds.
Are you for real? Flat trajectory on such a heavy bullet propelled by such a small charge? I bet my shotgun does better.

I'm with legi0n on this one. Not enough case, too much projectile.
All the power to anyone who wants to do this sort of thing, great to make it work, I applaud their abilities, but I suspect its just a big bullet for the sake of a big bullet.

The only thing that interests me there is "how quiet can you get it WITHOUT a suppressor?"
Carpenter is a steel manufacturer and not a type of steel.
158 Carpenter is a specification set out in the TDP for mil-spec bolts.
158 Carpenter is not used only on entry level bolts so I don't know if you were fed this horse crap or if you came up with it yourself.
Stainless steel is relatively soft but can be hardened by heat treatment however the carbon content in 158 carpenter is one of the reasons that it is suitable for the manufacture of bolts.
Here you can see the total specification package of 158 Carpenter.

Just to be clear, I didn't come up with anything. All I did was cut and past from another article.
Thanks, makes more sense now.
To be perfectly clear one of my responsibilities as a senior gas technician is to maintain 2 endothermic generators for one of my clients who does military and civilian heat treatment.
These generators produce endothermic gas which is used to produce atmospheres necessary for the scale free hardening, carburizing, and carbon restoration of steel.
I go a little bat#### crazy when people talk out their ass.

I think it's an interesting little cartridge but definitely not with those bullets though. I'm thinking cast lead all the way. Firing those heavy match bullets would be fun for ####s & giggles but it would get rather old after the first box of bullets due to cost.
It's probably a case of "because I can" as opposed to any real need. A .458 SOCOM would be more versatile in my opinion.

Those of you skeptical about case capacity must not know a lot about subsonic rifle cartridges. Fast pistol powders are often used in small quantity to produce a fast impulse rather than a gradual acceleration as with rifle powder. This ensures full burn before the bullet leaves the bore and minimizes the potential for a squib bore obstruction (it's also cheaper to load a few grains of pistol powder versus say double the amount of a fast rifle powder or Trail Boss).
Consequently, a large case capacity is not required nor desirable. In fact a low volume is sought for two reasons - primarily because small volumes of powder will lay flat on the side of the case wall rather than taking up the full space of the case, making ignition from the primer unreliable. Secondly a poorly-understood and rare phenomena known as secondary explosive effect (SEE) has been observed to detonate guns when this condition exists.
By filling the majority of the cartridge case with the bullet and using a low volume, fast burning pistol powder you are maximizing bullet weight for best energy delivery while making the most efficient use of space for the case. No wasted space, high reliability. Sounds like a solid concept to me.
