I have a really nice Brno Israeli 308.
It was rechambered to .30-'06. It was a horrible hack job done by a muppet
I am getting it rebarreled.
I want to "restore" it to 308 with a new barrel
Since the barrel will be new, I want the best possible quality.
any idea what I can expect to pay for this service?
I am also thinking of tunning the rifle up with lapped bolt, rethreaded and refaced reciever and squared bolt.
any advice, ideas or reccomendations?
You can find 7.62mm Norway barrels floating around. Nice tubes!!! Not so sure I would do anything except rebarrel it. Get it parkerized by Chuckindenver, actually have him do the entire job. I have 2 of these rifles upstairs, both nicely parked. Good luck.
This question seems a little bit like asking to put a new engine in an old car. Yes, everything is possible, but is it a worthwhile financial decision? By the time you've put a new barrel on an old rifle, you might have spent $200-$300. And you still have an old rifle. Not economics that I like.
Get an estimate from Chuck. You were planning a free gunsmith? Chuck will do it right and hold down expenses.
its not really like putting a new engine in an old car but thiers nothing wrong with that either, many people do it. old is relative. its a really nice gun so its justified up to a point, up to a point is not free.
Its blued so I'm going that route
Another question I have is the choice of chamber dimesions. SAAMI ammo specs are one thing but I'm looking at chamber specs. Semi auto chambers are loose, bolt gun chambers are tighter and Palma match type specs are tighter still? I'm new to this and I want to be able to understand what my gun smith is asking when it comes time to make these discisions.
now is the time to make choices that will assist and support precision reloading goals and increased accuracy potential. I doubt I will be rebarreling this rifle again in my life time.
Depends on what ammo you'll be using. If you're going to load special match ammo for this then an extra tight chamber is OK, but I'd keep it to SAAMI spec. If you intend to use ball then tell him that. That can help make the decision of which chamber ream is employed. I don't think you need too tight a chamber...If you get a used original barrel, the decision is already made. It should be OK...
I intend to reload. Bench rest standard
Then it depends on the dies you intend to use, how tight a chamber you want.
thanks,
others have mentioned chamber reamers as a possible source of dimensions. how do chamber reamer manufacturer's select the dimensions of thier reamers? where do those dimesnions come from?
I dont have control over reloading dies beyond the act of buying them. others have stated that the chamber reamer used to ream the chamber is used to manifacture the reloading dies. I dont want to get into the act of designing reloading dies in order to be able to get my chamber reamed. I'm going with .308 so it wont be a wild cat cartrige.
It seems ther's got to be a starting point that everybody references from in thier choice of dimensions for the chamber. i know saami dictates cartridge dimentions but how much larger must the chamber be, and remember this is not a gas gun. I'm trying to take advantage of the opportunity to select chamber dimensions to maximize aacuracy potential.I'm not designing a wildcat catridge, I just want to know whats involved in the decision to choose the chamber dimesions so I can help the gunsmith decide or at least under stand why he might make certain choices.
Maybe it was a mistake to mention bench rest standards. That just refers to the effort to reload to a very high standard. and we're not talking wildcats here.
There are other things that are more important then chamber dimensions in the pursuit of accuracy. Fit of the stock. Bedding in the stock. A floating barrel or forend pressure on the barrel. All of these play a more important role then the chamber. As long as the chamber reaming is true and you know how much lead you want in the throat, then it's up to you where to go from there.
Cole's Dist. has the Norway 7.62mm barrel at $99.95. Grab one now. They are mint and will not last.
this was about making up a new barrel for a brno mauser.
the dimensions of the chamber are critical. Because I have a choice and a decsision that must be made befor the barrel is made. once the barrel is made, its too late.
the barrel is the primary and key determination as to the accuracy of the gun.
even I know that much. I read enough books on bench rest shooting to know that.
Its about selecting the dimensions of the reamer that will cut the chamber, considerations include, but not limited to saami specs, resizing the brass after each firing (or not hopefully) as well as accuracy. Its a bolt gun not a class 3 weapon so tight rather than loose.
At this time Remington seems to be using an extremely tight chamber ream on their SPS rifles. They won't chamber just any ammo. Reloads won't always go in. You'd have to use a small base I think. Maybe this the way you want to go. That way if you aren't quite satisfied, you can always go up in size.
