25-06 into 9.3x62
#192886 - 01/11/11 07:40 PM

Hi everyone.

Just thought I'd put up a post on my rifle, a Winchester Classic, being rebarreled from 25-06 to a 9.3x62. My preference lately is to have rifles that are not needlessly heavy for calibre so after purchasing a Kimber Classic Select Grade rifle in 25-06 I was thinking of a pretty easy rebarrel for my Winchester rifle. The 9.3 seems to be making a real comeback and thought this would be a fun choice.

Anyway, AFRO408 agreed to do some work on the rifle and hopefully will post up some pics here of the progress of the transformation. It's very nearing completion......

Here is a pic of the donor rifle-

Cheers,
Mark.

Sounds interesting.

Re your comment "The 9.3 seems to be making a real comeback and thought this would be a fun choice."

It made the comeback years ago.

Yep John, that's the one. Thanks to Fatboy for supplying some dummy rounds for testing the feed. Hydros at that.....

Cheers,

1.....re barrel in 9.3x62, 23" long.
2.....Express sights ( fixed rear ) Ivory front sight.
3.....Bolt release built up and checkered.
4.....Ebony or Horn forend tip, to hide the old sling swivel hole.
5.....Rust blue all metal work.

Some progress photos of the job.
Unscrewed the 25-06 barrel and got all the relevant measurements for fitting the 9.3 barrel.
In this first pic, you can see the position of the extractor and feed cutout, on the bolt face, with the bolt locked in firing position.
http://i568.photobucket.com/albums/ss122/243myra/P7070004.jpg

The controlled feed Winchesters have a cone breech and a cutout for the end of the extractor.
http://i568.photobucket.com/albums/ss122/243myra/P7070003.jpg

All the measuring tools needed to fit the barrel.
http://i568.photobucket.com/albums/ss122/243myra/P7070001.jpg

Depth gauge, thread pitch gauge and my home made Headspace micrometer.

The barrel looks like it will fit nicely, without much stock removal. Only in the Knox form section.
http://i568.photobucket.com/albums/ss122/243myra/P7140004.jpg

After reducing the Knox form diameter, to the same as original barrel, I cut the barrel to length and got it running true, so I can then ream the chamber and screwcut the shank.
<iframe width="420" height="315" src="http://www.youtube.com/embed/QzxMuM3kOqA" frameborder="0" allowfullscreen></iframe>
I managed to get this bore running within a quarter of a thou. You can also see how high the lands are in this Walther barrel. Each division represents .001"

http://i568.photobucket.com/albums/ss122/243myra/P7140005.jpg
The 9.3x62 reamer has a particularly long throat and I took a pic of what the throat looks like, before cutting deeper. The reamer had just started cutting the neck recess.
http://i568.photobucket.com/albums/ss122/243myra/P7140003.jpg

The barrel is chambered, threaded, crowned and fitted to the action, the next thing to do is to cut the extractor recess.

Setting up the barrel shank to cut the extractor relief.

Cutting the relief.

The barrel fits nicely.

I first 'tin' the matching surfaces and clean all traces of the acid flux from the pieces.

The sight bases and sling swivel are soldered on nice and level using 6% Silver solder and resin flux.
I then clean all the excess solder off with a soft chisel, diamond hone and emery cloth lubed with Kerosene.

Barrel in the white, ready for sight regulation and bluing.

The original bedding was good, but needed relieving behind the square lug below the rear tang. This is a common problem that I encounter and on a large cal rifle, contact here will result in splitting the wrist of the stock, or removing a complete wedge of wood.

A mortice was cut for the secondary recoil lug and some wood from the side of the channel for the sight base.

Front Night sight was fitted and some metal needed to be removed from the bottom of the dovetail, to allow the flip up night sight to work smoothly.

Rear sight leaf was fitted and will be regulated to 50m
The rear of the sight bases was stippled as well.

The bolt release lever knob was built up with weld, shaped and knurled.

Talley cross bolt was fitted behind the recoil lug and then it and the bolt release were Nitre blued.

Thanks heaps Tony.....

Just one thing, the sights were to be regulated at 75m.

Lovely rifle. Looks like the stippling is a hit.
Dead on at 50 meters would be great.

FWIW I thought that a nitro bolt action round if sighted for 25 would also be on the mark at 100.

That is one of those "rules of thumb" {AKA Old Wive's Tales} that if "Minute of Pie Plate" is your goal is close enough to true, but isn't otherwise.

Depends on sight height, and of course specific quirks of rifle and caliber.

No.

It doesn't work that way at all. Next time you are at the range, bring a pile of rifles and loads and try it. You might be impressed with some and others not even a little bit.

Yes, it doesn't always work out like that.

I used to shoot Field Rifle with a .308 and it was zeroed at 200m and was spot on at 25m.
The target distances are 25, 50, 100, 200m, so I would aim directly at 25 & 200, hold at 6 oclock on the ten ring for 50m and at 6 oclock on the 9 ring at 100m.

Agree with what 9.3 and Afro say.

Whole range of calibre specific factors come into it,
although by changing components you can get a number of different calibres to have roughly the same trajectory.

The test firing and regulating has been postponed ( calf branding next to the private range that I'm lucky to have the use of ) so I did a bit more work on the stock, fitting the Buff horn forend tip.

The old forend tip had to be cut off behind the forward sling swivel, squared up and the dowel holes drilled.

The piece of Northern Territory Water Buffalo horn was given the same treatment.

Then the pieces were glued together using this boat building Epoxy with it's anti fungal properties. It's nice and thick and doesn't run back out of the joint.

Sight regulation will be next week now.

No worries Mark.
What goes around comes around....................I hope.

Will be a joy to use,I have two.

I too think the 9.3x62 is on a big come back when you can buy a $550 Zastava or an $1100 Ruger with express sights as well as Sako Black Bear.

After shooting Scrub bulls with the 375H&H and the 9.3x62 in the last 3 months I cant tell the difference between them.

You will love it as Tony does Great work.!!

It's a wonderful cartridge. I once converted a M96 Husqvarna from 9.3x57 but since I already had a .375 and a .404 and a .450 I couldn't figure out why I had a 9.3x62 as well. So I sold it to a friend who wanted an elk rifle. I'm kind of sorry that I did, now. That thing was a pocket rocket, light weight and hit like the hammer of Thor. Maybe I should start looking for another M96 . . .

Looking forward to a shooting report from AFRO. Woodleigh 286gr RN loaded to about 2350fps. A few guys recommended this load so assume it works, just hope so in this one....

She's now ready to go afield. I finished fitting and shaping the Horn tip today.

G'day everyone! Caught in the act of scraping the barrel channel and shaping the outside of the tip.

It's getting warm here, so shorts are dress of the day.

Took a couple of pics of the girl in the sun.

Probably get out to the range on Thursday now. Weather permitting.

Cheers

Flattery will get you everywhere mate.

The lovely garden is my wife's passion and pride.
She goes through about 10 tons of mulch each year and plants a lot of new seedlings each spring.
The gardens are getting larger and the mowing less. Yay!!
