7 PRC SAAMI approved

[TX Badger]

I could care less what Hornady says because their brass sucks and I hand load. But it does seem like whatever they promote gets popular enough for Lapua and other quality brass makers to pick up. That is the launch I am interested in. If I can get 7 prc lapua or alpha brass and do not have to pay for custom dies…. I'm in.

Who's is building what with this caliber? Action, barrel, barrel length, stock, brake-suppressed? What bullet and powder combo?

 

[nksmfamjp]

Just clarification…
What I meant to say was that if the 7mm prc were built off the 6.5 PRC instead of the 300 PRC, THAT would be silly.
Hope I didn't offend anyone

No offense, but my view was the opposite. I think I'd rather have something like an ideally throated short action fat 7mm.

What I saw was like 7 Rm sized roughly. Not sure where it fits.

I'm planning to build one as soon as brass and dies become available. Right now I'm thinking a Pierce Shadow LA nitride coated, 26" Lilja #5 spiral fluted, McMillan Game Hunter, some sort of side port brake but not sure on brand yet. For bullets I'm thinking Berger 175gr Elite Hunters or 180gr Hybrids. As far as powder, probably RL23, RL26, and H1000. One of them will work good I think.

It's not like it is stopping anyone from putting a fast twist barrel on their old rifle. If the only thing it does is encourage them to make heavier and better bullets for their new cartridge, I can't wait.

It has been hell trying to find heavy 7mm bullets the last couple of years and hopefully, this pushes all the ammo manufacturers to build 160-190gr bullets and keep them on the shelves.

No, no it don't but the majority of people want to just buy a gun and it's ammo off the shelf and anywhere else and shoot. Most common folks are not going to put custom barrels or have a smith make an existing older cartridge with the saami spec of one twist rate into another just to shoot heavy for caliber bullets…..these people ar not people here, they are the shoot once in a great while people. Most people if they don't have to spend any money to make something work, they won't buy it.

You won't see 7 blazer, 7lrm, and many other other wildcatters cartridges (that are better), and that have paved the way for this miracle, because they don't have the money to pay saami off. It suck when there's only one organization that can approve stuff. pretty much a monopoly. who ever has the most money, Can make the most money. I'm not whining. I'm just saying if there were two or three more approval organizations out there, the people that have paved the way could get there deserved piece of the pie, If they wanted it.

Saami ammo comes in a box at a specific length. Not your own custom length. My good friend has a new browning X bolt in a 300 PRC that won't shoot any factory ammo to under 2 moa at 1K. I took his rifle, and with very little load development, I had it shooting 1 moa. It may be great marketing, but it will turn into hype very soon, by the popular crowd. Everything these days are played with popularity in mind.
I can see the life style influencers now. Don't suffer the embarrassment and insecurity that comes with owning a measly 7RM, 7SAUM, OR WSM.

Yes, that is why I mentioned them and they were talked about in this thread with the apples to oranges comparison, some are make your own brass, buy brass from one or two places and the other will have a plethora of options of bras and so on. Of course you won't find those on shelves, that's why Hornady is smart and capitalizes on the cartridges they produce.

I have no idea what it would cost to get saami approval but you have to pay to play. At the end of the day it's just like if you invented something and some company changed a few things and then capitalized on something similar to your product……it's capitalism, love or hate it.

Of course saami ammo comes in a specific lengths, it's not custom ammo lol……that's why they have the specs of the min and max coal…..for the ammo manufacturers to have their loads come out with differing bullets the correct length or else you'll have issues…..that's why saami exists, to standardize the rifles to the ammo and ammo to the rifles.

Not sure about the Blazer, but the owner of Gunwerks stated on a podcast or in an article that the reason they couldn't get SAAMI approval was because they had a couple different versions of the LRM. Since they had sold rifles with different versions they had no way to know what chamber the new ammo would get shot in. This is also why the 6.5 x 284 never got SAAMI approval. It has nothing to do with paying people off.

This is why it makes more sense for Hornady to create a new cartridge instead of changing an old one. You can't manufacture 260 ammo with 147 eldms because someone that owns a 1990's rem 700 with a 1-9 twist will expect that ammo to work in their rifle.

 

[Ucsdryder]

How does it compare to the 7 SAUM?

Nothing compares to the 7saum!

 

[Prieto9000]

The 260 is better, Put a long throat on it and a fast twist, It will out perform the cm wonder cartridge anyday of the week, And so will the Swede. I do beleive the 6.5 PRC is better than the 6.5-284, Only because it does not have a rebated rim, And it is a more efficient case.

And yet the specs for the 260 state that it must not have a fast twist nor a long throat and because of that it can't out perform the creedmoor. The sweede suffers from the same problem. It is specs put it on the low side of the pressure spectrum so decent factory ammo is not available.

Duhh lol. The reason I stated this is the hype made in the past of being able to shoot accurately with box ammo at long distances. It's simply a crap shoot. There's a lot of people that don't get that accuracy due to the load being off from what THAT particular rifle likes.
Sometimes it drastic. The claims in the upcoming videos should say, some guns may vary, hand loading is recommended.

And for the average hunter that shoots his new wisbang LR rifle once a year before hunting, This is a bad combo, and accounts for a lot of lost, gut shot, three legged animals.
But it is what it is. Sorry for the hijacking. I'm out.

That would make no buisness sense since they are in buisness to sell rifles and ammo. Its called personal responsibility to educate yourself and verify you can shoot accurately at the distance you are shooting at game.

It may be great marketing, but it will turn into hype very soon, by the popular crowd. Everything these days are played with popularity in mind.

Not sure I understand this statement. Are you saying they should not try to make their product popular through marketing? If it doesn't become popular they just wasted their money.

It's funny how everyone says that like its the only reason hornady's offerings are successful. Yet everyone on this site builds custom rifles and ammo to do exactly what they're cartridges do. The 6.5x284 was a pretty successful cartridge developed by long range shooters that wanted to use heavy high bc bullets at decent velocity. But if you wanted one you had to build a custom rifle and ammo. Was it marketing hype that it was successful? Or was it successful because it worked? Is the 6.5 PRC successful because of marketing hype or is it successful because now everyone can get 6.5x284 performance from factory rifles and ammo?

No this is not even close to true...
In another post you said the 6.5x 284 wasn't approved by saami, well it was.
The 6.5x284 Norma is saami approved and has been for almost 2 decades, also the saami throat is set up for 140 Bergers.

Savage and multiple manufacturers have been offering 8 twist rifles in this chambering for a long time now.
The 6.5 prc will at the very best get you maybe 50 fps over the 6.5x284 Norma.

So yes its BS marketing that propelled the PRC to the top, and guys who aren't truly invested in the world of long range are gobbling it up

Hopefully LA necked down 300PRC.

That would put it around 90 grains of water capacity if nothing else is modified (which it likely will be because the lawyers say we can't have a 7mm round that will chamber in a .308 barrel). That's WAY superior to the 7 Rem Mag, but not quite as harsh on throats as the hotter .28 Nosler, 7 STW, and 7 Ultra Mag. It will likely fit better in a standard long action like the .28 and not require an extra long version like the STW. It is a more efficient design than the STW, for sure. It should also have slightly less recoil and blast compared to the larger cases. I would not be surprised, however, to see it lengthened slightly and/or have the shoulder modified to prevent chambering in a .300 PRC chamber. In that configuration, it would be basically equal to the STW in capacity, but more efficient. I think it might make more sense to shorten it slighly, slightly lengthen the neck to best accommodate 195 VLDs or 197 SMKs and blow it out .010" or so to maintain capacity and prevent accidental loading into a .300 chamber. I think topping out about 87 - 89 grains of water makes the most sense for a 7mm. Keeping the design very efficient and increasing barrel life a little more makes more sense to me. There would be plenty of power there for propelling the heaviest 7mm bullets to extreme ranges keeping with a 65,000 psi max avg. pressure. I think a little less is more for this bore diameter at the top of the power spectrum.

What I saw was like 7 Rm sized roughly. Not sure where it fits.

I think what he's getting at is that we already had those around in the 7 WSM, 7 SAUM and the Sherman shorts. While the 7 SAUM definitely wasn't throated where it needed to be, custom builders have no problem throating anything to proper depth. Also, how much performance do you gain over the 6.5 PRC, 6.5 SAUM, and 7mm SAUM, and 7 Sherman shorts?

If it is indeed ONLY 7 Rem Mag size, then it's likely to be not enough different from that or the 7 Wby in performance and the same argument holds. However, it it's fatter and has a longer neck than the 7 Rem Mag, and has a capacity in the upper 80s to low 90s grains of water, that puts it near the STW and 28 Nosler in performance level while shaving some recoil and blast, while adding some barrel life.

The only way a short cartridge in this design is beneficial over things already available, is if it's fat enough to hold at least 83 - 85 grains of water. That means it would need to be nearly Lapua-sized except way shorter.
