7 PRC

Testing ballistics new 7 PRC at 1000 yards programing the Sig kilo 10, shooting Hornady factory ammo in 175 ELDX bullet everything worked perfectly got a new lot of ammunition so I had to re-run ballistics luckily no change this was the 1000 yard group in 5 mile an hour cross wind at 1000 yards out of this fusion Barbourcreek Rifle built in a terminus long action Zeus benchmark spiral fluted barrel eight twist

Group is 1000 yard 5 mph wind from 9:00

Working with a Custom Built 7pc for a month.
Takes Fed 215 to bring the heat, don't waste time on CCI250. H1K is stellar, Hornady cases
Final load data @100yrd target, adjusted 1/4moa to left dope shot to 1K @ 250ft elevation
This is provided as a base line hopefully to provide some direction due to limited data. Hornady posted data is quite close, they done their homework with this PRC. Factory ammo is as good as it gets with this cartridge.

I was on the mindset these new cases are pointless but I'm a reloader. Until I decided to get a 7 prc and bought factory ammo (still waiting on barrel) I really understood what hornady was trying to do. With the prc line they give a modern case design but does the 300 prc do anything 300 win mag can't do no I think there basically the same thing performance wise. But where the prc line stands out is the new twist rates for modern bullets and factory ammo for the better bullets. Allows you to have the bullets set out proper without going custom. Unfortunately so many 300 win mags out there and can't produce the better factory ammo because twist rates and throat lengths. I now find the new designs awesome and I think if the things keep going in the long range shooting stuff more and more prc will be sold and the 300 win mag and 7 mags will suffer in the future. I'm a guy who shoots 30 nosler 7-300 win mag and I'm excited for the 7 prc just to have good factory ammo option.
Best summation I've seen for PRC cartidges.

Will they do anything a 300 Win Mag, 6.5x55 or 7 Rem Mag won't? Realistically: Darn little. EXCEPT they are looking ahead rather than back.

Twist rates & throat lengths. Yielding the ability to fire long bullets efficiently. TWO benefits - heavy-for-caliber and mono bullets.

I'm halfway thru my 70's already. Ain't gonna live long enough to make much difference in my hunting (unless maybe I make it to 100 in perfect health). Odds of that: HA! But it will to whomever hunts in 2048 with my planned 7mm PRC.

Lead bullets could be unobtanium by then but Hammer can already spin up & ship premium bullets in days rather than months. Sorry, Berger, et al.

In 25 years handloaders may be CNCing their own affordably. Try telling anyone 25 years ago they could anneal cases at home as precisely as does an AMP. For $760 ($1400 today in 1997 dollars).

7 RM's will be around for decades not years. As will the other 'older' cartidges. But the world itself will be different. In some ways we cannot imagine today. But the idea that hunters will no longer trek wilderness after wild game is unimaginable. In fact, if our world continues changing along SOME of the lines we see now, it'll be more crucial to real adults - and their families - than today.

Survival of the fittest may depend on both unprocessesed protein and the hunters mindset (including abilities to pick off two-legged predators & their drone helpers).

Conjecture. But while some of our offspring may be using 30-06's & their contemporaries, more will be shouldering arms optimized for the cartridges of furure: Long range, efficient powder burn, optimized bullets they can make themselves.

Think about it: How old was the 30-06 when the 7RM came out in 1962? Six decades, mas o menos. About the same span as '62 til now.

Yeah, I'm gettin' / makin' a 7PRC - with one of Mr. Wheeler's problem-solvin' reamers. I'll use it as long as the Lord allows & somebody (maybe my oldest grand daughter) will, I hope, be shooting it then.

Spot on! Glad to read your post.
 
Not to bash any cartridge, but does 7 PRC do anything a 280 AI doesn't do? I see a few load configurations that exceed the AI by 20-50 FPS with 175 bullets and I get that for many who want to squeeze every FPS they can out of a cartridge, this may be the way to go. I'm happy to see so many supporting fresh concepts in cartridge/ bullet design. It keeps the industry interesting and viable. I bought a 6.5 Creedmoor when they were first available and it has become my defacto hunting round, I built a 300 Ham'r this year and love it but I'm not throwing out my 30-30 nor my old 270, both of which will efficiently take any animal in the lower 48 and I prefer my 6.5x55 AI to the 6.5 PRC simply for round count in a given platform, they perform the same. These are my thoughts and I whole heartedly support the old song, "it's your thing, do what you want to do!"
I've been shooting my 7mm Rem mag now since the mid 60's and it still performs just fine. I've never fired a factory round through it and don't intend start now but the old girl will spit out a 175 gr partition at just under 3100fps and the 160's are right at 3200. Between it, my 7mm Mashburn Super, my 7mm Weatherby RPM and a couple other wildcats of my own design, the PRC does nothing for me. As to cases I have enough to last a few lifetimes. I just think the PRC is just designed to separate us from our hard earned dollars.

That it is..Hornady is a Master at Selling new things..It does not do anything my 7 Saum can do.With both the 7SAUM & 7PRC Both using 195 gr Berger EOL,and same powder the 7PRC uses more powder to go 30 fps slower than my 7 SAUM.
 
My son, has already bought, 3 Boxes of Factory, 175 ELD-X Ammo and, a Brake,.. he just ordered, the New Rifle, Today !
The 7 PRC, will REPLACE,.. MANY older, 7 Magnums and, the 6.8 westerner.
Hornady has Hit, 3 "Home Runs" in a Row with, awesome, Cartridge Design,.. the 6.5 Creed, the 6.5 PRC and, the New, 7 PRC.
And their Bullets, AIN'T "Bad",.. either !
Everybody and their Mother in Law, will make, Brass and Rifles as,.. it's, gonna BE,.. Popular !
My grandson has killed, 3 Deer ( W/ ELD-X's ) with, his very accurate, Savage Ultra Lite ( Proof Barrel ),.. IT's,.. a "Tack Driver" with, reasonable, Recoil !
And the 6mmARC another Over The fence HIT...However it wont replace the 7m REM Magnum in our lifetime..Still too many rifles out there to be handed down.I am considering rebarreling my Browning White Gold Medallionwith the 7PRC though..LOL
 
I just got off the phone with one of my PA buddies.

He was telling me about his successful elk hunt in Montana last month.

He shot a nice bull at 905 yards.

Bergara 300 PRC with Hornady 212ELDX.

$1,000 rifle off the shelf
$500 worth ammo for practicing/ dope chart on the range they cleared.
$700 scope

Legitimate good guy that had never shot at an animal over 350 yards.

He & his buddies worked up a dope card for his rifle.

He was successful because the components were readily available & he worked with those components to make an ethical harvest.

Could he of done the same thing with his 300WM or a Nosler?
Maybe eventually he could have, but not as efficiently as he did with his 300PRC.

That's what I see these PRCs being.
It doesnt take that much to kill a big Bull Elk. I shot one at about 550 to 600 yartds with a 270 130gr silver tip. It took 3 steps and rolled down the hill.With that said I have a 300 PRC & a 30 ShermanMagnum I shoot in ELR competition. Its a great round and the 300 PRCis an $1800 factory gun that shoots equally as well as my $6000 Custom. ..Som is that a Freakish deal.?I think not.With these CMC machines the gun builders are all getting better even the over the counter guns. We get hung up on always going bigger..Myself included.Hedll the INDIANs killed them with Bow & arrows.

I suggest trying a different powder if you are consistently getting slower results from the 7 PRC than the 7 SAUM. The PRC is a considerably more potent cartridge according to all published load data I can access freely on the internet. It has 4 grains (5%) more case capacity after all.

Here's a direct comparison of Nosler's load data for the 7 SAUM vs Hodgdon's load data for the 7 PRC. With identical powders, bullets, and barrel lengths, the PRC outruns the SAUM by over 100 fps, and when optimized, over 200 fps.

I understand that individual rifles vary, but even if one compared the slowest 7 PRC barrel to the fastest 7 SAUM barrel, it is unlikely that the 7 SAUM would ever outrun the 7 PRC with properly developed hand loads.

Based on published data (and physics), there are only two "common" cartridges that match or exceed the 7 PRC, while staying within reason of SAAMI specs. 28 Nosler and 7 Rem Mag.
