Re: chambering by hand 6.5x47mm

Roy, that may have been a little harsh. and I have nothing against a guy doing his smith projects on his own.

But, there are some projects that if done improperly can and will cause someone to get hurt. From the info in this post it was one of them.

OP, If you really want to fit a short chambered barrel, forget about the action truing, buy a deapth mic, fit a standard thickness factory or aftermarket lug, and find good information on the subject before you begin. In most instances if the barrel was set up properly you can get away with hand reaming to finish depth.
OR stick with savages.

Might be because anyone in the business hears this kind of 'dreaming' every day! Procedures not thought all the way through or done not even knowing why , ideas that aren't feasible, things recommended on forums that can/may cause physical and or property damage or even death. I've thought many times about changing my signature to; "Gunsmithing,,,,, So easy a Caveman Can Do It!"

Spot on good advice. There are more dimensions than headspace to be considered. The OPs idea was going to lead to bad stuff happening.

Your asking for advice on somthing you don't have much knowledge on.
Save your money and and take your action and barrel to a smith and have it done right, before you hurt yourself or someone else.

Re: chambering by hand 6.5x47mm

Most smiths have done some hand reaming to increase head space,freebore,neck diamenter,
neck length and throating, but only in small ammounts .002 or .003 thousandths. but everything
else is done on a machine for accuracy and trueness.

I personally don't like pre chambered barrels because they limit the tolerances .

I understand wanting to do it your self but as CoyBoy said I think it is not the place to cut
corners(To many bad things can happen).Poor smithing is what lead me to doing my own
but i bought all the right tools before I started.

Other things like adding pillars, bedding or customizing stocks may only hurt accuracy. But
poor assembly and chambering of an action can /will kill you.

So I would not recommend doing it ether.

Why spend $300+ for tooling and only have the job done part way.

So now that you cut your threads oversize, your going to screw on a barrel that will have a thread fit that is .010+ undersize, How is that going to help your accuracy?

Thanks for the input coyboy.but i think there may be a misunderstanding about my post so please let me clear this up,I dont have this rifle sitting on my work bench about to slam it together half @#% without any proper knowledge or with out some good reading and I had no intentions of chasing out or recutting the threads just true the face of the receiver and lap the bolt lug..Ive built savages 110 with great results and I know thats alot easier then the 700rem so I'll get all the proper info and help before I tackle this project..We have to ask and read and watch to learn before we do ..My question was more about the short chamber barrels having enough room in the short chamber to install the barrel fully and properly with a badger recoil lug to then finish the chamber by hand without having to cut the shoulder anymore after the intial cut, that being measured after receiver facings ,bolt lapping and new lug measured I'm not going to just throw the barrel forward leaving the differance of the factory lug and comp lug as exposed case and space between bolt and barrel..but i know if i mess up cutting chamber by hand then off comes the barrel back to the lath and recutting shouder again.., another concern i had was the kind of results people have got with hand cutting chambers like chattering etc....this post is to begining of alot of reading and asking before ever starting the project That would be no time in the near future..I would never do this without knowledge and research..everyone who has done this before started somewhere and learn from other people by asking questions and after learning I may very well decide to do the bedding ,lug lapping,truing the face and raceways,and muzzle crown myself and leave the barrel install to the lathman if i find it not worth the trouble ..that being said i am greatful for all input but I'm not a jackleg thinking that this is easy job that any idiot can do with a barrel vise and a set of headspace gauges,just a guy wanting to gain knowledge about a skill and these questions are the first step to that ..but like you said after learning i may decide to stay with the savages..

Vipersnest,

There are some great DVDs out there by Darrel Holland, Gordy Gritters, and others doing it correctly on a lathe.

Kevin Cram has posted some of his work on youtube...
Blueprinting a Remingotn Action Video by MCR

...no doubt there may be just as many on youtube doing it incorrectly.

Here's a related thread regarding hand tools...
Action blueprinting??

Good luck and be safe!

Re: chambering by hand 6.5x47mm

Just adding that thicker recoil lug will move that pre threaded barrel out to a point where more cartridge base will be unsupported. If the lug is too thick, the base of the cartridge will blow out and destroy the rifle if not kill or maim you and whomever is next to you.

Lots of reading and maybe an NRA summer gunsmithing course would be advised.

60,000 pounds of pressure is nothing to fool with.

Be careful...............
