A new, big-bore air rifle with a computer-controlled valve:

"Although the initial offering is a rifle in .357 caliber (imagine the hundreds of lead bullets now made in this caliber!), a barrel change allows conversion to .30 caliber and even .410 gauge! For the first time in history, we may have an air shotgun with power identical to a firearm! I’m talking about sending a half-ounce of shot out the muzzle at over 1,100 f.p.s.!"

What little I know about it is posted here (not the rifle shown in the picture, read down to the second paragraph):

Jacketed Ammo?

I am led to wonder whether the anticipated .30+ cal barrels will work well with jacketed ammo (FMJ and the like), or whether that would result in excessive wear.

 
Jackets

While I certainly have no knowledge of what Crosman is planning, I don't think that a standard jacketed bullet would deform to the rifling easily enough.

Think back to the black powder days and you will find that the 'old ones' were able to attain remarkable accuracy with cast lead bullets with no jacket at all. They later experimented with paper wrapped bullets and then the copper wire wrapped bullets that came after that. These early 'jackets' were more a reaction to leading of the bore when velocities began to creep up higher and higher. The gas checks were a solution to the base of the bullet melting from smokeless powder.

As you increase bullet hardness in cast lead bullets by adding tin the melting point goes down. Higher velocity needs harder bullets to prevent them from exploding on contact with a big game animal, and they needed the gas checks to protect the bullets. You also need harder alloys to prevent striping at higher velocities.

The advantage of the jacket in relation to down range bullet performance followed later.

Don't think that the air gun velocities will go up that much due to th new technology as much as velocities will be far more consistent.

All that aside, I would buy one tomorrow...

Yeah, lead only, according to the discussion in the comments.

FWIW, 1/2oz = 218 grains. Toss that at 1100fps and you are solidly in .357 magnum territory. This is a powerful gun.
 
I would guess that 1100 fps velocity will be obtainable with the light 90 grain bullets they have designed for it, not the 218 grain bullets. 9mm and .45 caliber air rifle have been available for quite a few years. The Sam Yang 909S pushes a .45 cal 180 grain at 780 fps for example. The LA Safari from Quackenbush shoots a .457 510 gr bullet at 700 and has been used to take a bison.

Well the bullets will be a buck a piece...if you can afford to shoot it you should be able to afford the rifle.
 
"I’m talking about sending a half-ounce of shot out the muzzle at over 1,100 f.p.s.!"

He (Tom Gaylord) is talking out his rear. Pure BS.

This rifle will shoot any soft lead .357 round, so it is actually very cheap to shoot. I can get 150 .357 boolits for $12 (just bought 750 .45Colt slugs for $90 shipped for my .45 air rifle). "Suckers" are the only ones that are going to buy airgun slugs for $1 a piece.
