Name one who isn't. I suspect its more about you disagreeing with his opinions



Ron Spomers take.

Generations of the Scottish losing to the AB's hasn't done much for your mood, has it

If high pressure brass becomes a thing what would you build?

I'll finally get a 18" Dasher and shoot 105s ...

I didn't say it was shit. I called bullshit on marketing hype that says it will have less recoil than other same calibre rounds firing same projectile at same velocity.

spooner covered that though and it does because it about the amount of powder being burnt rather then pressure like most people think uses alot less powder so makes sense

either way you look at it and its a bigger step forward then what the 7mm PRC was promised then turned out to be so pretty exciting pushing higher pressures with less powder in these steel cases is pretty interesting
my 300 win mag shooting 180gr bondstrikes is more then enough to satisfy my needs and shooting to 500ish

Really? He's a guy that gets to play with guns everyday. I'm jealous of that, but wish him the best. One of the few US YouTubers I watch because he doesn't go on about 2A bollocks and isn't prepping for a zombie apocalypse.

I listened to him on a podcast a while back, came across as a smart guy whos figured out how to make Youtube pay for the lifestyle he's always wanted. He hunts overseas too, mentioned taking his kids to Africa to hunt.

If we don't support new idea's they will cease to be developed. Sure the driver behind this development is sales,it has to be simple as that.
I am most excited at where they could go from this neich cartridge technology when applied to existing chamberings,using special actions and cases.

Can you imagine the push back when nitro powder was developed, people had to throw away their existing guns and buy special projectiles that they could no.longer case in the open fire in their parlor?

The ammo cost in its biggest market will be much less because of economy of scale,anyhow the cost of that single vital round is fuck all compared to all the other stuff involved in a hunt.

I wonder how suppressors will handle the extra pressures from this cartridge

I can't agree with that, Newton's third law says that when two bodies interact by applying force to one another, in this case the gun and the bullet the effect is equal on both but in opposite directions. It's the mass of the bullet and the speed it reaches along with the firearms weight that determines recoil not the amount of powder burnt to do that.

The mass of powder is taken into account because it is also being pushed down the barrel just like the projectile, even if it is also in the gas form.

wrong.

exhaust gas (velocity, pressure,...) contributes significantly to recoil.

otherwise muzzle breaks and suppressors would not have an effect...

The recoil claim does have merit, as powder has mass and is being thrown out along with the bullet.

Graph below from shooterscalculator.com... 175gr bullet at 3000fps in a 9lb rifle. Only change being an increase in powder charge weight... 60gr for a 7BC, 70gr for a 7PRC, and 80gr for a 28 Nosler.



Obviously with the different performance characteristics of the above cartridges, the three rifles would have different length barrels to get the same MV and keep it apples to apples. But it shows that there's a useful recoil reduction to be had by using less powder.

I'd take another 4 inches of your old rifle. 12 inch barrel throwing those 80eldms at almost 2700fps.

Refreshing to see a manufacturer not bend over for the big boys.

Yep suppressors will HATE this cartridge with a short barrel, the muzzle pressure will be way higher than normal & higher than most magnums especially given the powder burn rates most likely being used

Brakes will LOVE it, tons of pressure to work with, even an inefficient design will work acceptably

Will be interesting to see how the whole concept progresses including reloading, assuming its possible
