Worn 30-06 barrel slugs to .323 diameter

[browningautorifle]

From what I have experienced, when we were lining barrels, the practice was NOT to sleeve hi-powered barrels because of the pressures involved. Yes, .30 cal barrel liners are available. Yes, they're in a 1/10 twist. Manufacturers just hope I guess, that one won't try to line a 300 something or other mag. Liners are usually thin so you can't cut a shouldered rifle chamber in them, it would just be like sliding a drinking straw into a barrel. Most liners are used for the low pressured cartridges, say 35,000 or so. 30.30 can also be done but they are still down there in pressures...

It wasn't a matter of finding them on line, if you ask, you'll find a full range of explanations that resemble mine...

could just get a new criterian barrel for it , they are very accurate when used on garands and the twist rate is just right for garand load.not sure if that was suggested or not but for the price can not beat them , johnsons are not that hard to change out and headspace.hope that helps , way i would go , your up to 8mm @.323 not good, wayyy too big to use in a garand or johnson
without destroying the op rod i would think or breaking or bending an even harder part to get for that old johnson.New criterian barrels run about 175.00 and would make that old johnson shoot better than the day it was produced. I am a gunsmith and could turn that barrel on a lathe and cut her down a tad recrown and headspace for the johnson, they used the exact same load as the garand did, i personally as a gunsmith and armourer would say time for a new barrel, or leave it be and keep it for the collector value, once you change it it has lost that to most all milsurp collectors, the rifle is worth plenty as is and most who own those do not fire them often as with the german G43's they are finnicky and can be broken easily and parts are not just laying around for them.Nice old rifle man, if you want a shooter rebarrel, if you want it to keep its value as a collector .leave it alone and hang her on wall. It is a great old peice of history.And pretty rare anymore. @ 323 if 8mm brass will not chamber it hasnt been rechambered and 06 will fire in it ,hitting anything with it is another story. Was me i would leave her be, it will just grow in value guys that buy these dont go shooting them a lot for a reason.

An M1 barrel would be more difficult to machine down than an M1903 (A3)...more meat at the back. He's in the works of getting an 03 replacement barrel to do I think. Besides, we're in Canada and new barrels are hen's teeth here. Not much chance of getting a Criterion at anything under astronomical prices. And then there's the state dept thing...war material you know...

By the way...you do know we're talking about a 1941 Johnston rifle don't you?

Agreed an o3 barrel would be easier, But its an autoloader rifle and best to use a autoloader barrel i say on them. OH I SEE he is in canada, well lucky to even have a semi auto then lol, the last one i did one we used a garand barrel for it , it took a little more turning and all but came out a sweet shooter and the guy loves it , still he does not shoot it very often as i told him they can be finnicky and do have a rep of breaking down. Why the army dept chose the garand over the johnsons.Far as i know only a few marine regiments had johnsons but way before my time man. yes i saw the johnson in the pic.I have worked on a few of them in my day.Here in states most that have them do not shoot them very often for that very reason,parts are hard to get and i have had to mill a few parts to even repair a few. Still its a great old piece of history if left as is. Good luck nice rifle man. even if you never get a barrel its nice as is for a collector they go for a premium over here in states even if they cant be fired, they just want to say i own a johnson and have it in their safe to complete their us ww2 era collections. We here at ssk ind. in Wintersville ,OH try and keep em authentic as possible these collector guys are fanatical about it. and i mean downright fanatical. Point being on the barrel the lathe does most the work anyhow, not like we hand turn barrels lol. Canada huh ,would love to hunt up there once.

YOU, are to say the least, full of mis-information...

???

Madness.

[browningautorifle]

I refer to post #25...on that part...

[jimb16]

Are you aware that Johnson made 8mm barrels for the rifle? That was done so that "enemy" ammo could be used. Do a chamber cast. You may have a very valuable and rare barrel.

[mil-surp60]

NO i do not know that much about those rifles, but he said an 8mill did not fit, im guessing its just wore out .But if thats the case , yea he has something very rare , the fact he says it has 0 rifling left is what concerns me on it just being worn out , and are they not limited on how many rounds a semi auto can hold in canada my last report was 5 rounds , i have converted a few tokarev svt mags to hold 5 for people who live north of the border to hold only 5 rounds is that just for hunting? im no Canadian ,never been to canada , just know what the customers who were going there said thier limit was on semi autos and rounds they can hold or removable mags being legal , do i know for sure well no, i do not live in canada i live in a gun friendly state so you are right my knowledge of canadian gun laws is limited , but i know they dont have 30 round ars and aks laying in their closets like 70% of we americans do. Please fell free to enlighten me on that issue, can always learn.I have only had the pleasure of actually working on 4 authentic johnson rifles, just not a lot of them around and they are quite costly to buy. I do know for a fact the army ord.dept turned it down for the garand for a reason. they were just to finicky for long term use for the army in ww2.Expert on then no, but that much i do know. And i will always go for the thicker steeled barrel over a thinner one for any rebarrel i do, guess we all have an opinion on that, the lathe does the work. And i want anthing i work on as strong as possible, sure an 03 would work , but why not get the thicker bigger barrel is my outlook. Personaly i would leave it alone and leave it original it was mine, but that is just me.May be madness to you to me its perfect sense.Not all agree man, lets just enjoy the old rifle and see what he does with her. No reason to insult man.

Since cerrosafe is another hard to find item in Canada (thank god my parents didn't move to Australia!) I made an 8mm-06 round and it won't chamber. So it is 30-06 with an extremely worn barrel.

The retro-fitting of another barrel will cost at least half that of a new one, and then I have just one barrel and made a mess of a collectible. So I have decided to buy a new Johnson barrel altogether. This should increase the value of the set close enough to the cost of this 2nd barrel. I will have the original barrel for the collector in me and the 2nd new barrel for the shooting aspect.

If I ever get bored of it or need more room in the safe for another treasure I am certain I could get my money back. In fact I have never lost on any milsurp, even after just a few months of ownership. Can't say that about stocks, cars, or much else. Guns and Real Estate seem to be the best investment I ever made.

Thanks to all once again. Learned a lot here.
