How long until we see a 7 PRC to compete with the 7 SAUM ?

[Spotshooter]

I’m getting ready to build a 7 SAUM, and am wondering if the PRC will go that way soon.

PRC brass might be better in the future ?

 

[Ranger188]

Their are rumor about it, but your still using Hornady brass
for it at first before maybe someone else making better down the road.

 

[Zero333]

7 PRC and 7 RSAUM are practically identical in performance. Thus making it hard to speculate it's future.

 

[moondog]

6.5 PRC and 300 PRC cases are not the same. The 6.5 is close th the 7 SAUM. The 300 PRC is close to a 300 WM. A couple of guys have done the 7-300 version with good results I hear.

 

[Preacher]

The 7 SAUM has more boilers room...
If brass is a problem find some ADG 7MM SAUM brass and end the problem...

My bet is Hornady will be releasing this sooner than later. They are not ones to miss an opportunity to market yet another redundant caliber in shiny red packaging to the easily duped masses, touting it's superior performance and ability to fit in a short action.

Arms and ammunition manufacturers have been doing that for 100+ years.

a 7 PRC on the 6.5 case is just a 284 win. 6.5 case necked up is 69.3 gr capacity Hornady case. lapua necked up for 284 is 68.5 gr.
I have both and would opt for your brass preference on which one. I wont do a 7 PRC until better brass comes along.

 

[STOMP442]

The 6.5 PRC is just a 6.5-284. That didn't stop them before and it won't stop them again.

 

[Walt Krafft]

28 Nosler?

 

[Ranger188]

If I had to guess, they would neck down the 300 PRC case.
Wouldn't make any sense to neck up the 6.5

The 7-300 PRC is a hammer, have a friend building one right now. Not sure that a case that overbore is commercially viable for Hornady (7mm RUM sales never really took off, and the 28 Nosler controls that space from a hunting perspective).

It’ll eat my straight 300 PRC alive out to 1500 or so with 195s.

 

[Hohn]

Even with a bullet like a 250 A-tip?

I’m not aware of any 7mm bullet that comes close to that BC.

Interesting. What bullets/ velocities is he running? Barrel life??

He’s shooting for 195/3050 and hoping for 1500 round barrel life. Our local range only goes to 935 so this is plenty of heat and it’s still close enough that the 245 at 2700 out of the PRC loses in drop and wind.

Rumor has it 3200 is achievable with the 195s, but over a really hot load and with barrel life in the 800s.

Edit: not exactly apples to apples though, 30” 7mm vs 26” 30 cal.

Ummmm, noooo......

284 Win has outside case diameter of 0.500".
PRC, based off of the 375 Ruger case is 0.532" outside diameter.
Giving the PRC more of a jump in case capacity than PRC to SAUM, WSM.

My oppinion.
Build it & someone will buy it.

I am using a 29 1/4" barrel on the 300 PRC. With the 200 smk, 3100fps is still showing very little in the way of pressure signs. The 220 ELD-X is running 3053 fps, but I wouldn't go further with it. Both loads are shooting under 0.5 moa @600 yds

You’re making me regret cutting the barrel for a can! That is FAST.

I'm a few weeks into a wait for a 7/300 PRC reamer from Manson.

For a couple apples to apples comparisons:

The SAAMI spec for the 300 PRC is 2800 fps with a 225 ELDm from a 24" barrel at 65,000 psi.
Using a similar pressure, COL, and a single based powder, QL estimates 3040 fps with a 180 ELDm from a 24" barrel. It estimates ~2945 fps for the 190 ATip at the same COL.

The unfired Hornady and ADG 300 PRC brass only have a couple grains more capacity than the Norma 300 WM brass. With the 300 WM, I get 1200-1400 rounds. Loaded to similar pressures I'd expect the 300 PRC give similar, but slightly less life. Experience with other wildcats suggests that necking down the same case from 30 caliber to 7mm with reduce barrel life by 1/3. Another way of looking at it is the 30 caliber version will last half again as long.

Figure ~75 fps more from double based powders in cooler weather, another 150 fps from 75,000 psi instead of 65,000, and another ~30 fps per inch of barrel length. Bullet problems start showing up at ~3100 fps with a 1:8 twist, especially if you're shooting strings. ~3200 fps will further limit barrel life and the ability to shoot strings. The 7/300 PRC gets into those limits with the heaviest long range 7mm bullets at reasonable pressures for the available brass, without the use of double based powders, and barrel twists/lengths that are available off the shelf.

At 94-95 grains of water, the 7/300 PRC case capacity fits in the case capacity gap between the 7wsm or 7rm at ~82 grains of water and the 28 Nosler at ~100 grains. I think it'd be even better if it had a little less case capacity like Tooley's 7mm BooBoo. A 7/300 WM would drop the case capacity into the window I was actually targeting, but at the loss of the ADG brass option. I also looked at the 7 LRM, but couldn't get past the markup on Hornady components. It is a well thought out option though.

Using RL26 and hornady brass. This thing is an absolute hammer. Using a Harrell tactical brake on it.
