As I have posted in other threads, I really don't need another rifle. In fact, I've sold off a few over the past year. That hasn't kept me from getting bit by the 7mm PRC bug ... and I like to tinker. I am nowhere near as skilled as some of you who can do your own machining, and I'm not prepared to try and chamber a barrel blank, so another Remage is in the offing. I'll post progress here.

I've been assembling stuff for a couple of months. Found and bought a donor rifle in early February: a 1989 Remington 700 ADL in 7mm Remington Magnum. Sold off the scope and ammo that came with it so the barreled action set me back about $420. If I sell the stock and factory barrel, it will be even less. Here's the donor rifle sans scope and rings.

I made a couple of unsuccessful attempts to pull the barrel myself. My problem was I could never get enough purchase on the barrel to keep it from rotating in the vice blocks. Think I'll explore some good aluminum blocks in the future.

Today I took it to a custom gun builder who took about five minutes and $20 to break it free. He did it without marring the barrel. Over the next few days I'll get the receiver all cleaned up.

I have a McGowen "Remage" barrel on order. As this is going to be a hunting rifle, I ordered a 24-inch Remington magnum profile in polished blue with a recessed crown to match the blued receiver. It will probably be a few more weeks before it's done. But the PTG Go/No-Go gauges I ordered in February came in last week.

Awesome Thread I can’t wait to see your build! Keep us updated as you go along!
 
Gotta use rosin with those hardwood vise blocks.
Yeah, there's rosin in there. The heat of the friction when the barrel turned looks to have "melted" it. At least it was shiny and hard after pulling the blocks. I noted my smith used rosin, but then wrapped the barrel with a turn of paper. I might try that next time I need to pull a barrel.
 
Would it help to lightly heat the receiver? I’m thinking hair dryer.

I have a whole house water filter. I can use a strap wrench with an extender cheater bar and still can’t get it off, pulling to the point that I’m concerned about crushing the housing. If I heat it just a little with a heat gun I can spin it off by hand
 
I tried heat on one attempt, but only had a hair dryer (my wife's; I'm bald :)). A heat gun might have helped. My smith got it loose without heat, though he said that would have been his next step. It's a C-prefix receiver, and he said Remington used LocTite on them, unhappily. I gave away my heat gun before my last move; probably time to invest in another.
 
I've read things here and there and know I won't get the round count of a .308. But for a hunting rifle, even 1,000 will be okay. I have other rifles for ringing steel.
Id expect at least 1500rnds, its not that large a case. Sub 70gr with most bullet weights.
My Nosler is eating 85+ and were at 400-500 with no real obvious erosion.

And hey when it does start to open up just run a 7-300 PRC reamer in there and go again lol!
 
Disassembled action, barrel, and recoil lug. Action should clean up easily. Eventually I'll install a Timney trigger from my stash of parts.

Here's the stock I'll be using. Darrel Holland laminated stock with Holland pillars installed. I bought it second hand. It has been bedded and I'm going to have to dig out the bedding in front of the recoil lug to fit the magnum profile and barrel nut.

Looks like a fun project, if I didn't like the 6.5prc barrel on my mauser so much I'd see about having a 7 prc barrel made up. But when I burn it up( not sure how long it will take with its cold hammer forged barrel) it will be a hard decision if I got 6.5 again or the 7mm.
6.5 PRC gang rise up! Lol, I wish I had unlimited money, otherwise I'd be buying a 7 PRC and 300 PRC to test.

They are like 30-40 bucks at Lowe's for a 120v corded unit! Of course, at work I have a Milwaukee M18 heat gun that runs off batteries, it's very handy for electrical work.
 
Wind and rain kept me from the range today more's the pity, as I was off work for Good Friday. So since I'm still waiting on the barrel from McGowen, I did some work on the stock. Lots of Devcon in front of the recoil lug that needed to come out to make space for the magnum barrel and barrel nut. Took a while. I chiseled out as much as I could and finished up with a couple of Dremel bits. Devcon dulls them up pretty quick.

Hmm, I didn't even use any glass compound on my 25-06. I just put it in the bare walnut stock and called it good after a few light coats of Tung Oil.

I would find it interesting if you shoot a few groups with the walnut and then glass bedding the rifle. The wood stock guns that I have glass bedded shot considerably better after.
