Have a SS 700 7mm Rem Mag - Into it for a pretty low price, someone has had the barrel off or at least put a different one on as it's about 90 degrees from where it should be by the factory marks.

Anyways - Already have two 7mm Rem Mags and tempted to turn this into a 7PRC. Believe the mag box is long enough, but many of you know a heck of a lot more than myself.

Thoughts/opinions?

Have a VX5 3-15x44 that needs a home, don't have a stock but plan to keep my eye out for something decent and light weight. Edge, etc?

Would like it all up at 7 1/2-8 lbs. Barrel suggestions and contour?

Thanks

69, When I got into 700s in the early 70's, my pal told me the 700 LA was one of the longest actions on the market. Good luck.

Mag box is more than plenty.

Should be an easy swap. I’d do a 1-8 2 contour. Minimal shank at 22-24” myself.

I was in the same boat as you. I ended up staying 7mm rem mag and throated the barrel for 180’s I couldn’t be happier with the results. I had great Redding dies and a bunch of great brass (ADG) now I know the prc is new and I wanted it bad but when I realized it did the same job I decided to not reinvest in another set of dies and brass. And at the time last year hornady was the only option available.
Now I have 3 7mm REM Mags tuned to different bullets depending on what I’m after. BTW. 2 shots 2 deer this fall with the new rifle.

I did
Bartlein Remington Mag sporter profile at 26”
Remington 700 SS action
Factory hinged floor plate
Trigger Tech trigger
McMillan Sako Hunter stock
I’ll weigh it later tonight

^this here.

I built my first 7mm RM several decades ago, because I got a 7mm barrel real cheap, like $40, asked a buddy if he had a 300 barrel, no but I have a 7mm take off from a guy, that thought he needed a 338 WM to shoot caribou, doubt it has had 20 rounds through it. Let's see it. It went home to my shop. Shoots great, guess I have four 7 RMs now, the longer bullet, by weight, for the diameter does a good job. I do have 300s and 338s, but the 7 RM gives nothing away, for a hunting gun on plains game.

Thanks for the input so far.


The reality of this potential project, its a want and far from a need.

69 - don't listen to Beretz - it'll cost you money

Seriously, I have a 7RM inbound this week that will very likely become a 7 PRC. Beretz has been an excellent source of info as I was thinking through it. Not surprising the specs he posted above is what mine will be - depends if the 9.5 twist 7 RM will stabilize a 175 ABLR AND shoot well. If it doesn't, an 8 twist 7 PRC is on the way. My only concern with a CRF action is feeding beer can cartridges. I'm not opposed to an 8 twist 7mm Big Green.

8 lbs is a good weight for a magnum 7. I've had everything from 7.5 lb to 9 lb 7 magnums of various flavors in the past. The 7.5 lb variety are a joy to carry but suck off the bench and from prone (at least for me) - too much recoil for this geriatric woos. The 9lb versions are a joy to shoot but too much weight to carry into the backcountry. A couples ounces on either side of 8 is a sweet spot to me. If you run a brake or can, go with 7lbs if you can. And buy some good ear protection if you go braked.

BTW: Shooters Pro Shop has 7mm 175 gr LR Accubonds blems on sale - an additional 20% off. I may have ordered a few yesterday

Essentially your still gonna have 2- 7 mags only difference is it will say 7PRC and you will have to buy dies and brass.

I more than understand that, but have three 7mm Rem Mags at the moment if you count this one.

Reality of it like many of us, I could probably do everything I really need to do with one or two rifles already in the safe but that's not a whole lot of fun.


Anyways - Thoughts on one of these?

https://raggedholebarrels.com/product/wilson-barrel-blanks/

22" Carbon Fiber Wilson Barrels? Not sure if they do different contour or not, but #4 wrapped? Or should I go 20", plan to have a suppressor on this one.

Not a carbon guy myself. The length sounds like you’d get along okay being suppressed.

It’s tempting to just grab a new 1-8 M700 7 Rem and see what it does. I’m betting those wouldn’t stink either.

Good luck with what you decide.

Why 3-7mms then?
Alex Wheeler has a 25PRC that is set up for LA its running 133 Bergers at 3150.
Use Hawkins DBM and it will be fine, just my thought.
Or go up to a 30 cal, maybe even 338.
Out of all the PRC's this one intrigues me especially since I have never been a PRC fan, its just a simple neck down 6.5 PRC using 6.5 PRC dies.

I'm a same old same-old, tried and true kind of guy. Same rifle in .30-06 for the last 20+ years. No complaints but... Very out of character for me, I had a 7PRC built last year. Do it! It's fun. And, instead of going over the same old ground you and everyone else has been over for the last 100 years, you get to be a part of the "new" thing which is more enjoyable than I thought it would be. And, if you're going to be a part of a new, latest, greatest kind of thing, 7PRC checks alot of boxes. It's perfect for the rig you're talking about. For what it's worth my Douglas #2 at 24 inch is a tack driver. Might be the stock too. Outkast arms will put your 700 in a full length bedded NULA stock for $750 or so. Nothing wrong with the 7RM but if you like factory ammo, it might be a while or never before you see a factory box loaded with 180 ELDMs or 160 CXs.

Build it!

Great points thru out.

Isn't ALL of this want?!

7 PRC has slightly less case capacity than the 7 Rem mag, maybe .4 grain. So, it is a sideways move to go from one to another.


If you want to play with something different, then do something very different.

I've kept my SS Rem 700 7mm RM as a foul weather backup rifle to my Fancy walnut stocked .300 Weatherby, which is my favorite rife. I've also often thought of rechambering my 7 RM to 7mm Mashburn or 7mm/.300 Winchester. But last summer I fitted a Vanguard Griptonite second stock to my .300 Wby, so now I'm wondering why I should even keep my 7mm RM.

I had a similar thought in that OP has multiple 7mm mags in tow. Why not take the SS 700 platform with all its room and run a 300 PRC instead of wasting valuable space. If long range and formidable sustained energy out at 700+ yards is a goal, the 300 PRC smokes the 7 PRC. The 212 gr and 225 gr 300 PRC loads leave the barrel with around 4K ft-lbs of thump. Bullet weights and BCs with that launch capability are found from .650-.800, with heavy weight bullets found at 250 gr.

Why screw around creating another duplicate magnum chambering.

or maximize the Rem 700's to it's full potential, get away from that Hornady crap and do a 300 RUM and spit the 212's at 3400 fps or the 225's at 3300

nothing else even comes
close.... other than the 338 Edge

or are you skeered ?

Yeah, the 300 RUM is a horsepower heavyweight always wanted one in a custom Ruger No. 1 throated properly for max performance. There was a company years back that did only 300 RUM and 338 Lapua on No. 1s, they were awesome firearms and reasonably priced. I shouldn’t have passed.

There's always a few randos who don't kill anything yet lust for useless cartridges in rifles they will never own. It's even funnier knowing they could never handle the recoil well enough to shoot at long range and think some magic level of power will make up for their spastic trigger jerk.


OP it's a good idea to get a box of 7mm PRC and see how well they feed from the stock mag on you donor rifle.Will probably need a tweak to the mag box but you want to be sure the rail timing will work with the shorter case/larger shoulder diameter.

As you have said a few times this is a want and not a need but any 7mm throwing 168-180grs at +/-2900fps is pretty close to the best cartridge possible for North America.

Have fun.

Are all these memes an insecurity thing or are you just infatuated by them. I can assure you that if nothing else they are extremely annoying.

I totally agree with this. Launch a 7mm pill of 160 or better at 2900 plus and you've entered the grail. My 280 rem with 140s is right at 3 grand and it's lightning. Had a 7 rum that would shoot 168s at about 3050 to 3100. Its an awesome cartridge. But a 7mm rem mag with a 168 to 175 flying 2900 to 2950? That's where it's at. Don't jack up a good 7 mag for a prc bud. If your gonna go prc, build it from the ground up.

Burnstein is still pissed at being called out and exposed as a Yid Pedophile ....

and it shows ...., lol !

IN my rem 700 in 280 Rem with IMR 7828 with win cases and Federal 210 primers, I shoot the 160 & 162 at 2930 fps, a load right out of the nosler manuals #3 & #4.

+1 for the 7STW!

My Ruger #1 in 7STW shoots 160-162 gr at 3200 w/ H1000. They do not bounce off bulls.

I agree. Realize what you have. Don’t be impulsive.

OP, I have a Brown Precission stock (not a pounder) here that looks like I won't be using now. Rem 700 BDL LA magnum barrel channel. Previously bedded, no pillars. Probably could use a new paint job, for aesthetics sake, but completely useable as is. Please PM for pics and more info if interested.

You'll have to cut the threads off and some of the shank to clean up your chamber. If it's a factory barrel, then your done at 7 rem. If it's got some shank on it, you can maybe swing it, but if your going full out with a new barrel. Disregard

And I just built a 7 PRC. Gonna eat my words.

The 200th anniversary 700 was 7mm RemMAG

Wtf you just like to piss away dollars for minimal gain?
