Depends on the rifle, those 56mm are bit big for most lightweight ( under 7 ish ) rifles. Another good one to look at is the Zeiss 4-16 44mm about the same price point, with the 30mm tube the 44mm lets in plenty of light without having half a coke can on top of your rifle.

Do yourself a favor and just get a 7 rem mag. You’ll be disappointed at the performance.

Can you please elaborate? You spent hundreds of dollars reloading for this round and couldn't get it to shoot? You have say 4 7mmPRC rifles and none could shoot? Please elaborate. Thx!

I have built 10- 7 PRCs in the last few months alone. None of them are reaching 2900 fps shooting 175 gr bullets and factory ammunition. I can surpass that all day long in a 7 REM Mag. The PRC is inherently accurate, but not a high performer.

7mm mag doesn’t compare to a PRC in any way with heavies

It absolutely does. The 7Mag can do everything the PRC can and better. Like i said earlier, just the 10 I’ve built this year shooting 175 gr bullets, they have yet to hit 2900 fps. The whole concept and idea of the PRC case is that the throats are lengthened to seat the heavy bullets further out of the case (freebore).My 7Mag reamer with .188” of freebore built in, they will easily push 3010+ fps with 175 gr bullet, with some room to spare. You can not do that with the PRC. Sure, you can have a 30” barrel, but these numbers are all from 26” barrels. Don’t get mad at me that you’ve fallen for the hype. It’s a great round, but my point is, it does nothing better than the 7 mag. It’s a solution to a problem that didn’t exist.
 
I agree with the above. There's no replacement for displacement and IMO the 7 RM is near perfect in case capacity for 160-180's. The area where it suffers is if you're running a sammi reamer you lose a little capacity and most factory rifles don't have enough twist for heavies.

There's no way to stomp on a 7PRC and over come that without greatly exceeding pressure unless you're okay with 1 shot brass.

That doesn't make the 7PRC a bad thing at all but I do wish they had given it that tad more capacity of say the Gunwerks 7LRM.

IMO, it's essentially a 7 SAUM IMP. Again not a bad thing but you're not going to see 3k with a 180.
 
I own both a custom 7RM and 7PRC. I shoot 150 Barnes in the 7RM and 180 Berger hybrids in the 7PRC. I would agree with the folks who say they are basically going to deliver the same ballistically. You can lean on either to get some crazy speeds with "heavies" but if that's what you're looking for, it might make sense to go with a different "7" or shoot a 30 cal. FWIW, I don't push my ammo hard. I load the 150's/7828ssc at 3050 in a 24" Brux barrel and the 180's/H1000 at 2820 in a 22" Helix 6 carbon barrel. I certainly could get more out of them with 26" barrels. Maybe I could get a little more speed and still retain accuracy but they do everything I need them to do already.

The 7PRC shines with factory rifles/ammo if you want to shoot heavier bullets. To me, that seems to be the obvious upside right now.

Id like to see your velocities of a 7mm mag with a 175 to 180 grain bullet. Depending on barrel length, I’ve primarily seen the average muzzle velocity with a 7mm mag with a 180 Berger or 175eldx in the 2800 to 2875 range. Where as I’m seeing around 100fps faster out of the 7mm prc. Also the case design of the PRC is simply better and more efficient from a reloading standpoint goes.

That sounds awfully slow, especially with a 26 inch barrel. Hornady ammo?
 
Hornady came out and claimed that the speeds on their factory ammo wasn't accurate. Don't remember what the reasoning was but they came out and admitted it, but every report I've heard and seen first hand, the federal was shooting perfectly and guys reloading were able to get amazing results, blowing the regular 7mm out of the water with heavier bullets. That being said I have seen issues with over pressure for guys reloading, but once figured out it was an easy fix for most of them.

The PRC’s have been tricky with reloading because of re-neck sizing from my experience. Once Lapua entered the market with brass offerings it was quickly fixed.

Copy. I made too broad a statement. 7mm is a fine cartridge no doubt. We load for both and you would really have to push pressure in a 7mm to match a 7prc with 180’s and 190’s. Talk about a barrel burner if you tried to match ballistics with heavies and comparable powder charges in a rem mag

I don’t care either, but that’s not my point. My point is that there is a huge falsification on Hornadys part with the posted performance. A lot of these folks I’ve been working with are trying to reach out to 800-1000 yards thinking their bullet is traveling at 3000 fps and it’s really 2830-2850. That’s the issue I have. Many of the 7 PRC fanboys have graduated from their 6.5 Creedmore and they don’t understand how it all works

A 7 mag with 26” barrel and .188” of freebore shooting 175 gr Berger Elite Hunters are right at 3065 fps and there a little room left in the tank. Adding freebore on a 7 mag is the trick. That’s free whole concept behind the PRCs, freebore is in its saami spec. Do the same on 7 mag, and it out performs
 
Hey tay!

I Wasn't directing That At Just You!

When I Was Young My Dad & His Friend Was Always F'N Around With Their Loads For Their 7 MAGS!

I Don't Remember Which Powder Nor Which Bullets They Were using Or How Hard They Were TAMPING The Powder?

But They Came Up With Some Kinda BS Load & They Lost Accuracy!

So Bad They Had To Move In To 25 Yards (Guessing!) With The Target!

Then They Capped A Couple Off And The Target Had Some Shrapnel Holes As Well As One Main Hole Through It!

A Shot Or Two Later The Ole Man Couldn't Open The Bolt On His Gun!

And That Was When They Started Wondering If They Mighta Went A Little Far!

On Top Of That I Never Could Figure Out Why You'd Wanna Destroy A Custom Rifle?

When I Said I Don't Care If Your 7 Shoots Faster Than Mine It Was Directed At The Whole World!

I Like A Decent Running Truck As Well!

Mine Isn't Even Close To Being The BADDEST SUM BEACH Around!

But I Like Some Reliability With It As Well!

I Like A Decent Shooting Gun!

And I'm OK With Not Burning The Barrel Out Of It Just To Claim The Fame!

That’s fair. But if we are taking a factory 7mm rem mag to a 7prc. This is similar in comparing a 6.8 western to a 270wsm. Put a faster twist barrel on 270wsm and you have essentially the same gun. I’ve shot piles of 7mm mags and still is a work horse gun to me. Would be interested on the powder you’re using for the 7mm with 175 EOL… h1000? Retumbo? N565/N570?
 
My problem I can’t give up or see replacing my 7MMs when they shoot so dam well and those bergers have never given me a problem. I would probably buy or build a 7 PRC if I’d never seen a 7MM. My first Remington 7MM was Browning Belgium made. My Custom 7MMs love Retumbo

68 gr h1000. If anyone is reading this, It is over published load so you have to work into it. The freebore really unlocks its potential and case capacity.

I just had a 7 PRC built with a 22" carbon benchmark barrel. I've just started with load work up using 175 grain ELDX and I hit pressure at 3038 fps with 69.8 grains of N565. With the 162 grain ELDX I still wasn't getting pressure signs at 3081 FPS.

I’d love to see the chrony.
 
I don't really care for it. I like the 30s better but that last one I loaded for went 2980 with 184 bergers with retumbo out of a 24 inch barrel.

I had a guy shooting a .22 pistol next to me that my chrono picked up a couple of times, hence the giant standard deviation. Here’s my ladder test that day. Going to load up the 162s with 70 grains and the 175s with 68.8 and go with whichever shoots the most accurately. I was using a BulletSeeker chrono and a magneto speed.

where is says 300 on the paper that was me just verifying my .300 NMI

That’s impressive, that is the first I have seen in a 7 PRC under 26” reach 3000. I hope it’s a good shooter

My non factory non chitbox 24" 7 RM does 2950 with 180s and H1000 for accuracy. It'll exceed 3000 but accuracy isn't as good overall. It'll go full retard with N570 but it's certainly not as accurate and overpressure.

Nothing wrong with a PRC if you want a factory rifle but a 7 RM will outperform it when properly configured .190 FB and 8 twist.
 
Barnes has a new 160 gr lrx for the prc that performs incredibly well at all ranges. I just got my prc, I’m excited to see how well they work out of it
 
I like these guys , experienced handloaders , talking about the 7 prc. I’m 67 if I didn’t love my 7 MM , I would be building a 7prc
 
Two fleas were fighting over who owns the dog. One jumped to a new dog and said: My dogs better!!!

Both could take more than enough blood, so what does it matter?

Bottom line is if you enjoy tinkering, have at it. For me, I couldn’t care less what a bullets performance is past 400 yards. And out to 400 yards, there isn’t a significant difference between these calibers.

I have a Nightforce NXS 5.5-22x50 on my MOA Evolution Badrock. Believe me, I have the same scope in 56mm objective on a 308 and it is a lot brighter, don’t hesitate going with the 56mm objective.

I have a Gunwerks RevIx in 7mm RM that I have shot a lot of elk and deer with a 168 Berger HVLD at 2930 fps. My Badrock is shooting 195 Bergers at 2861 fps, it’s pretty impressive. I’m just getting used to it and breaking it in, the Gunwerks is going to New Mexico in a couple of weeks!
