So tell me abou the .300PRC?

Just saw a short video on the bulletin, is the .300 PRC just another cartridge that duplicated another cartridge already in existence, just to market new rifles and ammo? THat is what I feel the 6.5 PRC is, basically duplicates my handloads for my 6.5x284, within 100fps or less. Any thoughts on this, all feedback appreciated!
 
Depends on what you mean by duplicates another cartridge? What’s your intended use of it etc....?

The closes comparison in my book is to the .300wm and 300 Norma. In regards to the WM I feel it’s better. Where the WM runs out of breath and is over pressure the PRC is not. Compared to the Norma it’s more efficient meaning less powder and same velocity.

Also no belt and uses standard mag bolt face.

I’m running it on my F Open gun. Got another barrel for that gun and once chambered up is 6.5PRC as well.

Heres my thoughts, not sure how much its worth. If a guy is building a new gun from the ground up and wanting a big .30 cal magnum then the 300 norma or 300 norma improved is hard to beat. Several reasons. 1: LAPUA brass. Berger is even manufacturing loaded ammo with lapua brass for it. I have a 300 norma imp and its averaging 3/4"@400 yards off the bipod. I can push a 215@3300 if I want with reloader 33 or vv n570 powder or 3200 with h1000 in a 26" barrel. I didn't see any pressure with h1000 til I hit 3200 fps and even then it wasn't much pressure. However I backed mine down to 3100 as there was a stupid accurate node a mile wide and at that load the brass should literally last well over 20 firings. You wont find Hornady brass lasting 20+ firings. 2: the 300 is just an inherently stupid accurate cartridge. Probably the most accurate big magnum Ive seen. Even fireforming with factory ammo I was averaging .3 moa at 400 yards. I had some groups that were sub inch. When doing load testing the nodes were almost a grain wide. 3: It does all this while still fitting in a standard long action magazine while throated for heavy bullets.

I have a ton of Kelbly Atlas actions instock with .750 bolt diameters for 300 norma builds. They have a full nitride treatment and retail at $1100 with a rail. Thats the best price for any lapua bolt face custom action on the market, especially considering the quality that Kelbly's is known for. At this time I have way more demand for my 300 norma improved design than 28 noslers and Ive built several hundred of them.

Now if a guy has a 300 win mag or whatever and the barrel is shot out then a 300 PRC would make sense since its simply rebarreling to a different cartridge. No bolt swap required.

This is what, along with Frank's experienced assessment, is where I am on the 300PRC. My Surgeon 300WM still has life left so it won't happen right away. If I can truly get more from the 300PRC than the 300 Win Mag with 230 Hybrids then I can see me headed in that direction. Especially if I can get good brass and no belt.
As for brass, I am a long-time user for Hornady brass in 6.5 & 6 Creedmoor. It has never failed me and I've managed to get brass life that rivals the famed Lapua. I did get one 50 round box or 6.5PRC that showed issues with neck splits on the second firing but one call to Hornady and a replacement box showed up here in less than a week. To be clear, that was one box out of eight in the early production brass so I don't see it being an epidemic issue.

My amateur math states the 6.5 PRC offers 14% more capacity than the .284. and it does that offering a one tenth shorter Case. 300 PRC post are going to receive responses from guys with Overbore Cartridges.
 
Dimensionally, this new 300 PRC looks to be VERY similar to the 300 Blaser magnum.

Blaser has a whole line of belt less magnum cartridges most people have never even heard of.
 
What do you want to know about the 300 PRC. I've been shooting it since 2007. I introduced Accuracy International to the round. They submitted it to USSOCOM for their solicitation for PSRI. Between myself and the Hornady 1K BR competitors we all have a decade+ experience with the round.

Dave, - can you please tell us the case capacity in H2O if possible ?
It looks similar to a 30 Nosler, but I have little knowledge on the 30 PRC.

Thanks, - Ron

No joke? It’s been around that long?

It's similar to the 30 Nosler but not quit. The Nosler is .550" on the body. The PRC is .532" in diameter which makes feeding out of a box magazine much better or out of any magazine for that matter. We were shooting my BooBoo case based on the RWS 8X68 case but brass was hard to get at times so the Hornady guys said lets neck down the 375 Ruger. We designed some reamers and off we went. We knew it was just slightly oversize for pure BR accuracy work but it works well enough. Two years ago at the IBS Nationals in Hvy gun I tied for 1st place score and I think I was 5th in group. Not bad considering I hadn't shot in a year and was nervous as hell the first day. I was shooting the then unreleased 225 ELD-M's.
I'll get you the water capacity.
Hornady is loading ammo for a SOCOM unit and it's pushing 225's @2900. Pretty good for a round that just plain works/functions. No drama. No special action like the Lapua or Norma required.

Dave can confirm me if I'm wrong but if I recall correctly and I posted in a different thread it was 95.6gr. of water capacity. I only measured one case. I didn't do a sample of a bunch of cases.

Dave sound about right?

That's what I'm running velocity wise. 2900fps. out of a 32" barrel with a 225gr. and 230gr. bullets. Like Dave said, "It just plain works!" Does nothing stupid. I'm running a different powder then what Dave or Hornady has used/played with and I know I'm not stepping on it either. A good working every day load.

Dave, the 300 PRC case looks to be very very close to the 300 Blaser mag dimensions, a lot closer than your 30 BooBoo, where you all aware of the 300 Blaser when you were designing this new 300 PRC?

If anything it's close to the 30 Newton, and it's been around a Hundred years. Why would you ask this question? Are you insinuating Hornady Copied someone else?

I've never looked at the 300 Blaser. Why would I? We just went with what the guys at Hornady could make easily. The first brass was just necked down 375 Ruger. Probably made at the end of a run of 375. I still have about 50 rounds of that somewhere.

You're correct
95 grs. to base of the neck 100 grs. all full up.

It doesn't make a bit of difference to me either way, I was just asking a question. I think ideas/designs are often borrowed, then changed or improved, and marketed. This is no slight to anyone, but lets be honest, there are very few "original" ideas on this stuff and it's more about who does the best job of marketing.
 
rpierce, what brand detachable box mag system do you recommend for the Kelbly built 300 Norma, when the bullets are seated out long?
And what is the mag capacity?
Thanks...

Good point. For example: Probably the most efficient (if not the most popular) Ackley Improved is the venerable 250-3000 AI. The darlings of the wider shooting world today, the 6.5 and 6 Creedmoor, are essentially just the 250 AI (30 deg) necked up or down. I can run a fired 6.5 Creedmoor case through my Redding 250 AI full-length sizer die, use it to assemble my pet 250 AI load, and fire it with impunity in my 250 AI rifle. (And for what it's worth, the 22 Nosler is very nearly a 250 AI scaled down to 90% with a rebated rim.)

I have mine in a folding Manners EH1A with their DBM chassis standard long action magazines for the lapua. It is stupid smooth feeding. Doesn't feel like Im cycling rounds. Holds 5 rounds. However I would probably go with a slightly longer detachable magazine to allow more room for throat erosion/maintaining the same relationship with the lands. Also the never ending trend of longer/heavier bullets coming out will allow you to run it in the longer magazine with no issue. Accurate Magazines has some longer magazine systems available. For the lightweight hunting rifle Im doing for myself in the next month or so I will be using a bdl setup.
