What is your favorite new cartridge?

[Kind of Blued]

I don't own ANY arms chambered for these cartridges, but conceptually, I like the:

.357 Sig - 600-somethin' ft/lbs out of a thin,concealable, decent capacity auto is hard to argue with.

.338 Lapua Magnum - Everything about the round is impressive, except the price.

.204 Ruger - In spite of the projectile being a mere 32gr, it does some pretty unreal things to prairie dogs when said projectile is traveling at 4,225 fps.

 

[.cheese.]

Within the rules: .416 Barrett (I just love the idea that it was invented as a way to say "up yours" to .50 BMG bans).

Slightly older and not in the rules: .40S&W or .338 Lapua Magnum (both invented within a year of each other so about equally as old as each other). Both have become excellent modern day substitutes for older cartridges (.40SW is between 9mm and .45ACP essentially replacing them both by being a middle ground.... and .338 is the middle ground between .308 and .50 BMG not necessarily replacing them, but if you had to pick one cartridge for long range shots either hunting or otherwise, .338 Lapua Magnum has you covered 100% of the time more or less).

I really don't want to split hairs, but I wish to challenge your 90% assertion. I need additional information to believe it, because:
1) I doubt 90% of the hunters hunt in the eastern woods
2) Including all of the game you state (mulies, coues, pronghorn, etc.) definitely makes for a lot of western hunting
3) to say MORE than 50%, ok, I'd buy that one. But not 90%
4) I would agree that 90% of eastern whitetails are taken at ranges less than 100 yards.

I find the 90% assertion a little on the high side, never the less.

Just my 2 cents.

Poper

I've read that 90% figure many times in big name hunting mags, NRA mags, and from polls run on various websites. You have a problem with the numbers, take it up with them.

Makes my favorite platform have my favorite ballistics that actually fits my hand.

All of my cartridges are over 100 years old except for the .30 Carbine and .357 Magnum (and they're getting on up there.) So I guess I'll vote for the .357.

.357Sig .327mag 6.8 SPC

People have said before the 5.7x28mm round, but I think that a lot more could be done with it. If you play around with the chemistry a bit, and thin up the jacket of the bullet, I bet you could replicate the M193's terminal ballistics at short ranges in the 28mm case.
If you did the work for it, you could probably get a thin-jacket 55-grain projectile to something like 2500-2600 fps, or even more. As I understand it, the 5.7 is already underloaded.
That would be totally sweet for a SHTF/HD gun. Especially if you used the upcoming 5.7 AR upper. And made your own happy switch.
*drools*

 

[CBS220]

Considering the problems the 5.7 has getting near and a little above 2000-2200 fps with the flyweight bullets, I don't think it stands any chance of a 55 at 2600!

 

[EHCRain10]

17HMR and 338FED would be the tops for me
6.8SPC looks interesting as well

 

[Mac45]

I don't have anything that quite fits the OP's definition of new.
Newest I do have would be the .40 S&W, and the .32 HRM, and I like both quite a bit.
Of the new ones out there, I'd like to play with a .327 Mag, and I think the .458 SOCOM and the .450 Bushmaster look interesting.

 

[freakshow10mm]

I played with the .327. Not impressed. Sold it.

The 458 SOCOM does 45/70 ballistics from an AR. Cool.

The .450 Bushy is interesting, yes. Straight walled for good feeding. Looks like a .45 caliber 30 M1 cartridge. Perfect.

 

[v8stang289]

I like the .17 HMR, for the simple fact that it allows me to shoot at longer ranges than the .22lr without breaking the bank.

 

[Mac45]

I played with the .327. Not impressed. Sold it.

I agree that the .327 isn't terribly impressive, at least from a SD point of view.
I just think it would be fun to play with.
I'm hoping Ruger comes out with a Single Six in .327, or better yet, a Blackhawk convertible in .327/.32-20.
Guess I have a soft spot for .32's

 

[bnkrazy]

Both my wife and I are .17 HMR junkies. Groundhogs don't know what hit 'em.

Like necking it down to .17 caliber. That would be interesting. It would make .17HMR and Mach 2 look like a BB gun.

 

[MT GUNNY]

.22-250 Awesome!!

 

[GunTech]

6.5 Grendel has been very promising in the AR. My first 6.5 turn bolt arrives tomorrow and I'm looking forward to seeing how she shoots from a 22" 1:9.

 

[Dr. Tad Hussein Winslow]

I'm a fan of the .17 hummer, 6.5-284 Norma, 6.5 grendel, 9x23 Winchester, .22 Reed Express, and the .338 Spectre. I own guns in two of these 6, and plan to pick up guns in the other 4 before it's over with.

The .20 Calhoun Hornet, .270 WSM, .50 Beowulf, .500 S&W mag, .500 Phantom, .50 GI, .25 WSSM, and .204 ruger are a tad bit interesting and have their niches, I suppose. I have considered getting guns in all 8, but for now I've decided to pass.

I find most of the myriad of other new rounds to be mostly worthless, either as duplicates of old stuff, or unnecessary/indistinguishable.

MT GUNNY, .22-250 is cool round, but it was developed in the late 1930s.

 

[xx7grant7x]

i'll jump on the 5.7 bandwagon if there is one. I love the guns and the round can't wait for ar-15 upper in that caliber that takes ps-90 mags mwah-ha-ha

 

[tomwoh]

17 HMR - I hear the 5MM maybe coming back..

 

[Brian Dale]

MT GUNNY, .22-250 is cool round, but it was developed in the late 1930s.

I think maybe he's just pulling rank on the rest of us. {And hey! You kids get outta my yard!}

 

[Nolo]

Wow...
{SARCASM}.327 Federal!
The weakness of the 9mm Parabellum without the ability to buy ammo anywhere and all the inconvenience and sluggish reloading of a revolver!?
No way!
I must be in Hell!{/SARCASM}

By the way, CBS220, I did say you'd have to play with the chemistry a bit. The powder would need to burn "slowly" (relative...), which might actually make problems with high rates of fire. But still an intriguing idea to me.

Other newcomers I love are 6.5 Grendel (well, the ballistics, at least, I really hate the 11.7mm case head... saves you no space, and you really need it in the kind of rifle you'd use the Grendel in. You can tell I don't like the Grendel's case because I've been thinking of at least three cartridges that replicate its ballistics exactly with smaller case heads), .338 Federal (it feels like it's halfway between .308 and .45-70, which I think is great), and .500 S&W (still waiting for an EBR in it, though...)

 

[jakk280rem]

o.k. I'll wade in here with a vote for the .260remington.

 

[Dain Bramage]

7.92x57 cartridge commonly known today as the 8 mm Mauser.

The Germans lost me with the newfangled 7.92x57mm. It's an answer to a question that doesn't exist. It can't do anything the previous 7x57mm couldn't do, while using more powder, space, and having a harsher recoil.

Come to think of it, the 11x60mm was just fine and dandy. Why does everyone need to change everything all the time?
