True Velocity ammo

[LCazador]

True Velocity and Sierra bullets unveiled their composite cased ammo. Touting cooler barrel temps and perfectly concentric ammo capable of sub .500" groups! Not reloadable. I wonder how will it impact our shooting?

 

[rsmithsr50]

not I do not buy ammo

 

[Uthink Uknow]

Not reloadable? It would have to be accurate and dirt cheap to anybody but the dyed in the wool single minded hunter.

In the long run either hand loaders will be pushed out of the picture or new technology will have to be developed to build composite cases at home (3D printing?).

In the short term, I see no benefit to the average shooter, in fact, the whole marketing plan that True Velocity is presenting is completely suited to the military and eventually to law enforcement.

the press are the same people that brought you the
224 VALKYRE as a 1000 yard ar15 target round.
but never showed you a 1000 yard target
the test rifle was 24" bbl but most sold today ar 16/18/20.

no no...shoot it when 20 below zero

If it's the same clowns that brought us NATEC Ammo good luck.....

Worst crap around, sucked close to 4 million of US Tax Dollars right out of our pockets and no working ammo.

 

[Bill Norris]

Right they can keep it for my part. If I can load it I dont want it when it comes to center fire.

Right now they're only 308 caliber but here's their answer. Number one it uses less powder to accomplish the same velocity. The composite ammo was fired out of an FN m240b machine gun and a pic shows a guy holding a handful of empties. You can't do that with an M14 20 round mag full of empties and that's at semi-auto speed. The other thing they're touting is a complete caliber change on production machinery can be done in an 8 hour shift. A basic combat load of 210 rounds can be replaced with 300 rounds!Same weight! And shipping costs for our government go down! A pallet of 308 brass ammo weighs about 3100 pounds and a pallet of composite ammo weighs 2160 pounds! This is fascinating stuff!

2/3s the wgt, interesting - yes.
Afa the cal change in 8 hrs....big whoop imo. If you were a mom n pop shop, maybe only a machine or two, OK. But my guess is the big boys won't need that omgosh capability. It takes a while to get everything synched after a changeover. Bolting in assemblies is just the start. Tweaking and tuning can run the gamut from "No sweat" to "whatintarnation is wrong?" after a day anda half.

No real insight here as to wet environment durability, physical deformity resistance, residue greater or less than the powder du jour.
I caught myself getting a mindset reminiscent of what many probably had when they stopped stuffing from the front.
Time will tell.
Obviously we'll be handloading a long time . . . for our hobby. Military, police? Maybe the wave of the future. Don't buy whale oil futures. Elex may be round the corner.

The way I understand it is the heat transfer that occurs between the case and the chamber is less with the composite cases as they conduct less heat compared to a brass case. Whether this is 'keeping the barrel cooler', or 'keeping the chamber cooler' is debatable. I guess the technically correct statement would be 'reduces the rate at which the metal pipe attached to your action heats up as compared to shooting brass cased ammo'

 

[TAJ45]

Interesting. It seems X amount of heat goes someplace(s). If the case is majorly less of a heat sink, then where do it go?
It is intuitive to me to surmise that it is directed toward the only opening. Thereby leaving the chamber cooler.

 

[Dusty Stevens]

Its not like a brass case is a huge heat sink producing heat and in an auto weapon i cant imagine a brass case being in there that long contributes to any heat. Sounds like marketing gobblygoop

 

[Cecil S.]

The panicked heard gun buyers will be all over this!

 

[ebb]

Brass is a conductor, plastic not so much. If my construction learnin holds true. Metal window frames conduct heat into a house, the plastic window frames are way more energy efficient cause they don't conduct the heat into the house.

The first step to controlling ALL ammunition certainly could be to make it unreloadable. Next step: mandatory background checks for all ammo purchases and reloaders can no longer "fly under the radar".

...Is that a black helicopter I hear coming?

IMHO actually more than gobblygoop, more like BS. I've had a brass case from the guy next to me shooting an AR 10, bounce off my walnut stock and into my T-shirt pocket, burned my frickin' tit. A composite case will not carry as much heat energy with it out of the chamber. The heat energy stays there, contributing to heating up the chamber/barrel. I call BS. The brass case actually takes more heat energy out of the chamber than a comp case. Simple heat transfer physics.
