Looks like Hornady made the marketing decision to introduce the 300 Ruger under a more universal name. Welcome the 300 PRC. Still vaporware for now? At least a live pilot reamer could get you a 338 and 358.

New SAAMI stuff

Quite interesting

My guess is this will be compared to the 338 Lapua with less recoil. Ruger will come out with a precision rifle to match. Hmmmmmm

Or the 240 serria match king would make it a long range rig for sure.

Thinking of the .30 Newton, .35 Newton & .40 Newton...

Pretty much

lets hopes Ruger and Hornday achieve what Mr. Newton did not.

A large following for their rifles and cartridges.

I think it had to do with the bullets that were available back in his day...

Newton was ahead of his time for sure. This is a standard length case but it is designed to be a magnum length OAL and I am sure precision factory ammo to match a precision Ruger gun. A super size 6.5 Creedmoor of sorts. Question is, will it be worth the cost over a 300 Win Mag. Question is.... Will it clean up a 300 Win chamber?

It won't kill anything deader than the ol' .300H&H.

The 300 Ruger is just someone's idea for a gimmicky cartridge to separate hunters from their money.

What the 300H@H should have been in the first place.

Well good! Anything that sparks interest in our shooting sports is good. Now whip out a 7mm and 338.

No it will not cleanup a 300 WinMag chamber. I didn't bother to determine if it'd cleanup a 30/338 WinMag, but likely not to many of those around that someone would want to convert. Not knowing the exact chamber specification of a "short chambered" 300 WinMag barrel would be prevents knowing whether the 300 PRC reamer would properly clean the "short chamber" up or not.

You didn't ask, but the 300 PRC (Ruger/Hornady) will clean up a 30-06 chamber but the action will then require the requisite modification to properly feed the round; and of course the bolt face/extractor will require modification to accommodate the rim diameter.

Regardless, specification for the 300 PRC is for a 8.5" twist rate and the 10" twist rate of the 30-06/300 WinMag would limit bullet weight/length than can be utilized.

Had Charles Newton been designing a 3.6" OAL cartridge vs the 3.34" OAL cartridge I perceive the 30 Newton case design would have been very close to the 300 PRC case design.

I like the 300 PRC cartridge design. Though were I designing the cartridge I'd have optimized the parallel-sided throat length (PSTL) for a 3.6" cartridge OAL to fit the majority of "modern standard magazine" lengths. And its fairly easy to lengthen the PSTL for use in 3.75"/3.8" magazines for use of the longest high BC bullets.

Looks interesting.

I guess the title of the thread should be

300 Ruger ... Yes!

It's been a long time waiting. Now it's just a bit shy of the 30 Nosler, though the 300 PRC is a cleaner design without the rebated rim. All they need to do is market brass and do the 338 and things will be full circle from when they announced the 375 Ruger.

A nice thing about the 300 Precision Rifle Cartridge (based on 375Ruger with the shoulder set back a tad) is that it will work great for a 338, too.

The 375 Ruger had the shoulder too far up to allow for a simple neck down. But the 300 PRC looks like a neck expansion to .338" will leave a neck of around .333". Just about perfect. Just saying.

Back in '15 I built a 300 Dakota with a long throat so a 230gr Berger could be seated out at 3.650
The rifle was based on an extensively modified FN model 98.
The bottom metal was specifically designed for the cartridge and hold 3 down comfortably.
Set up with a Murphy precision 20 MOA rail and a Nightforce AtacR and 26" Krieger light Palma
With a T-Beast ultra 9 suppressor. Stock is a McMillan Mark X with sniper fill.
Other details of the build include full single point blue print of the receiver then re-heat treat at Blanchards.
New manufactured chromoly bolt with Borden bumps for snug lock up and 1/16 diameter FP. Speed locked bolt mod. Tubb pin at 1/16. 30 lb wolf mainspring. Custom retro Jewell trigger to mauser.
It's running the 230 Berger at 2980 FPS, with 1/4 MOA accuracy.

The long throat "bore rider" thing has been hashed and re-hased . It was the "edge" of the 338 edge.
It is what a 300 Win Mag mk. 248 mod 1 is. A 220 smk seated out long into 1degree 30 sec. Throat.

Wow Hornady is getting outside the box on this one, very cool. Wonder what the throat dims. Are.

Goofing around while work is slow.






300Win is in the back and 300PRC in the front. Easy set-back for a Savage or Ruger American?

Wookie76,

Thanks for the link that included a link to the SAAMI intro pdf.

The 300 PRC cartridge maximum dimensions are on this drawing,
as well as the chamber throat minimums, the latter in pencil:

Parallel-Sided-Free-Bore (diameter and length)
and
Leade semi-angle.




Rip ...

I doubt they will ever design a caliber that is "better" than a hand loaded 300 H&H, 30-338, or evend a 300 Win mag...anything better will just be proud flesh if you get my meaning!

Ray, that is how many people felt about the 30-06 when the 300 H&H came out !
You are starting to sound like an old fart

Just what world needs, yet another .300 with the same ballistics as a few others.

Maybe they do [need one]!

But my grandkids are going to get a 308 Win for their pre-teen starts.

My .300 RUM shoots the 225 ELD at bit over 3000 fps and under 1/2 MOA at 500 yards. Shot that load yesterday at 800 and 1190. Right on the money at 800 but four inches low (1.75 wind hold); at 1190 I was 1/2 min low but 1 min left (misread the wind?) with a 2.25 wind hold. My Lapua shooting 285 ELDs hit my 3 inch aiming circle at 800 with a 1.5 MOA wind hold and was 3-5 inches to the right and 2 inches high at 1190. I shot the Lapua first at 800 but the RUM first at 1190.

The .300 RUM is pretty impressive, but perhaps the new Ruger cartridge will deliver better velocity spread; right now I am getting an ES of 30 with my RUM but almost all Lapua shots are within 5 fps of my average (although the 1100 yard show was 12 fps less but still hit a few inches high).

As for the .300 H&H, a long cartridge that has a useless belt and a long taper. I would honestly prefer a .30-06 over that. Lately short and fat (even the Lapua qualifies there) seems to be the rage. My next gun is a .28 Nosler.
