Rebarreling my 7mmrem mag to .300 win mag?

I have an older Remington 700 7mag that I am going to rebarrel. I was considering having it rebarreled to .300 win mag. This may be a stupid question but anything else I need to consider when having this done? Or can I just have a barrel built and a smith install it? I have not spoken to my gunsmith yet about this. Just wanted to get some info from you guys. A friend of mine just told me about a local gunsmith that will blueprint and rebarrel a 700 action for $500. He uses Shilen barrels. Does this sound like a decent deal?

The reason I am thinking about going from a 7mag to a .300mag is because I have two 7mags and want something with a little more punch. What do you think?

My smith charges $325 for a blueprint and $275 for a barrel thread and crown. That doesn't include the barrel. Most custom barrels are going to run about $400 or so shipped. find out exactly what is included in a "blue print" from this smith.

other things to consider when building off a 700 action...

Are you going to get a new trigger or have the factory one tuned?

Are you going to get a new one piece bolt?

Are you going to have a mini M16 or Saco style extractor installed?

Are you going to replace the factory recoil lug with a heavy duty recoil lug pinned to the receiver?

Are you going to replace the firing pin assembly with a speed lock assembly or spring?

I did all of the above with my 700 300 Ultra build. Jewel trigger, one piece .704 PTG bolt, Saco extractor, heavy duty recoil lug and PTG speed lock firing pin.


I offset the cost a little by selling the factory bolt.

I appreciate the response. It makes me question even rebarreling this rifle. The only thing that has been done to this rifle is the factory trigger was tuned. I ordered a new stock that should be here shortly and I will have the action bedded. I don't really shoot "long range". 5-600 yards max. And I don't shoot compitition. Just deer, elk and antelope hunting. So is it even worth it?

For 5 - 600 yard shooting/hunting, I would want at least a sub MOA rifle. It doesn't have to be .5 MOA. If your rfiles shoot that well, then you don't "need" to rebarrel yet. That said, when Elk are on the menu, I like a big 30 cal. The 7 RM can get the job done but a 300 mag can get it done better with with more chance of anchoring a bull on the spot.

If you do decide to go ahead with the project, you might consider selling your 700 the way it is and putting the cash toward a full custom build. By the time you pay for blueprinting and upgrades you could use the sale $$$ toward a custom action and come close to breaking even, maybe even be a little ahead.

I like the 300 WSM over the 300 WM, especially if you're only shooting to 600 yds. The WSM case is a little more efficient and with RL17 you can match WM velocities and probably get more barrel life.

i have an older factory 7mm mag (1967) that is very very accurate. how does yours shoot now? do you reload? does it have a brake? what scope? i prefer a different brand barrel than you mentioned. brux, broughton, hart, kreiger others. none of my rem 700s have been blue printed.

My 700 is all factory stock. It is from the early 70's somewhere. It was given to me by my uncle about 6 months ago. It has an approx 20 year old Leupold Vari-X II on it that is clear and seems to work OK. This rifle shoots OK. Right around 1 1/4 " at 100 with factory ammo. The only thing that has been done to this rifle is a trigger job. I just ordered a new B&C Medalist stock for it. I figure with a good stock and bedding the action it should improve accuracy some. I do not reload at this time. It has been something I want to get started with but just haven't.

I looked into the Gunsmith that was offering blueprinting and rebarrel for $500. I spoke to him on the phone. He is a hobby gunsmith that does it only on the weekends for fun. He claims to have rebarreled well over 100 rifles and was willing to give me a list of references. His blueprinting is basically truing the action. I am going to talk to a couple of his references before I decide what I going to do.
