This was all performed in house. Except engraving. Judd did a mighty fine job on the engraving.

THF member "Freerange" brought me a 1956 Winchester 70 "Featherweight". It was chambered in .243 Win. He has enjoyed learning the ballistics of the 7mm-08 Ackley Improved I've written about so many times, and wanted the rifle re-barreled in that cartridge. But, he wanted to keep the barrel contour and length the same, and he wanted the new barrel blued. The only barrel manufacturer I found that makes a Pre-64 Winchester 70 "Featherweight" contour was Lilja barrels. And it's going to come in stainless steel. Not to worry, I told him we can Cerakote the barreled action a custom house blend to make it look like it's blued. "Do you want gloss, semi-gloss, or flat?" He said he wanted semi-gloss. That's going to be way down the line, but check.

First things first. We've got to install pillars in the stock, bed it, and free float the barrel channel.

Lilja dang sure provided plenty of barrel tenon.

After getting the bore centered with a .0000" Mitutoyo dial indicator, I could finally start cutting. I measured the angle on the Win 70 barrel and set out to match it.

[Linked Image]

Lots of measuring, part off the barrel, but leave me some wiggle room to face it square.

[Linked Image]

Get all that cleaned up.

[Linked Image]

More measuring, and careful single point threading.

[Linked Image]

Action screws on with no wobble.

[Linked Image]

The Pre-64 Win 70 bolt is a coned bolt. So the relief for the cone had to be cut next.

[Linked Image]

And, of course, it's got to get chambered.

[Linked Image]

Take the barrel out of the lathe, cut it to the same length as the Winchester barrel which was 22". Muzzle side out the jaws, rezero the barrel via the bore, and cut in the crown. 40 minutes of zeroing, 4 minutes of cutting and polishing. wink

Then we have a barreled action again.

Got the barrel cleaned. Found the lands with a 140 gr Nosler Partition and began fouling in the new Lilja.

I don't know how I left this out, initially. The Pre-64 Win 70 bolt has a Mauser style extractor. That's got to be relieved.

Great job Jason. I know that model 70 had the coned bolt, but I bet you had to do some work fitting the external Mauser style extractor. What was involved in that process?

Man, that is cool! The build appears to really keep the model 70 fwt look and feel. It looks like it’s gonna shoot too! Very impressive work JG. I’ve been hoping to get to see how that project turned out. VERY NICE. Anxious to hear your impression when you get it in your hands Freerange. Hopefully after you send a few down range…

I've got a stash. I've been buying loading components for a very long time.

This rifle is more than worthy of taking some of my Lapua 7mm-08 stash. I want that brass to last a long time, and I hope the rifle one day gets passed down to the next generation.
