Winchester Model 70

Still plan on getting a chamber cast done.

...and stamped. Maybe the gunsmith can do it for little more cost.

Many people have prejudice against push-feed M70s, but those actions are some of the best push-feeds ever designed. especially the ones through the 80s up until the classics came out in the early 90s.

The chamber "could be" .30-06' Ackley Improved, which was P.O. Ackley's work that took the venerable '06 just a little closer to the vaunted 300 H&H Magnum. Firing some moderate powered handloads will fire-form the case and you can then measure with your calipers. One way to find out, eh?

Does this Ackley chamber use normal off the shelf 30-06?

Does this Ackley chamber use normal off the shelf 30-06?

Yes, but it will fire form to 30-06 Ackley. It is safe to fire, but may not be very accurate.

I have been watching u tube videos on casting a chamber, doesn't seem all that difficult. Has anyone here done it?

 

[po18guy]

Does this Ackley chamber use normal off the shelf 30-06?

Yes. Mind you, this is all "IF" and that is a huge word. However, standard cases chamber and fire perfectly well. And the finished product is an "Improved" cartridge. 3000 FPS with a 150 grain and about 2825 FPS with a 180. Pretty serious North American game cartridge.

*** Consider buying a copy of Cartridges of the World - it is the standard reference and allows you to make sense of all the chamberings these days, all of the old cartridgers, all cartridges actually. Some will amaze you. Like 20,000 Lbs of muzzle energy. And it's not .50 BMG.

Casting a chamber is bonehead simple!

There really is no reason not to, and many that support the idea!

Is the ammo factory ammo? He could have already fire formed 30-06 cases, in which case, examine the shoulder. It also could be he had yet to shoot the ammo for fire forming.

It looks like a 30-05 will chamber in an A.I. chamber but the reverse isn't true.

The shoulder of the A.I. case will make contact with the beginning of the shoulder of the 30-06 chamber and go no further.

FYI re: 30.06 AI

Okay, yes to there was some factory ammo in the lot, some what I am guessing are reloads, and definitely not Ackley necked.

Have you taken the stock off?

Have you taken the stock off?

Yes
This is a 3 screw to stock configuration. Push feed bolt.

Here is a pic of the cartridges in question:

I labeled each one, as they came out of the boxes. Zero is NEW UMC factory ammo for comparison. One is Win Super X Olin manufactured. two through 5 are what I am guessing are the reloads. Cases are all identical, some of the bullets are a little different, look to me like mostly soft point hunting loads.

Might be the camera, but some of those necks look a lot longer than others.

yeah, sorry cheap camera in my phone. They are identical. yeah, just ran my calipers on them. All are exactly the same as the NEW UMC ammo.

Okay,..... next stupid question. To the hunters using 30-06 (if this in fact works out for me) would you or have you threaded the barrel, for a muzzle attachment, brake, flash hider, combo? The barrel does not have a front sight.

Personal choice here plays a large role....for me , Nope...no need for any of those items.

I'm in agreement with @Andy54Hawken on this. 30-06 really doesn't need a brake, and even if you do there are always unintended consequences like ear destroying noise, and venting gasses causing dust (makes it hard to track the animal) or even getting small rocks blown into your eyes when shooting prone.

IMO the only reason* to thread the barrel of a hunting rifle is for a suppressor. Note that in some countries these are not regulated items and are required for hunting. Benefits are they easier on the shooter's ears and less disturbing to others nearby. Disadvantages are more weight and a longer barrel. Bust use is with an efficient short action cartridge that doesn't need a barrel longer than 20" and shorter is better.

IMO your rifle is good to go without modifications. All it needs is a scope that fits where/how you hunt and enough trigger time to learn that particular rifle.
