I have a 03a3 that was sportized many years back by a unknown owner , It really needs a new barrel . I am a pretty good amature gunsmith but have not tried something like this yet . How is it done and are there special toos required ?

The rebarrel should be done with a solidly mounted, heavy bench vise, a set of barrel gripping blocks/rosin, and an action wrench.  Some barrels need to be cut, to releive tension, in order to be unscrewed.

Any different or new barrel should at least have the headspace checked, as a minimun requirement, with a set of headspace gauges.
If it's new, it may need finish chamber reaming to depth - yet another tool/process.

No disrespect meant, but if  someone isn't familiar with the process and these basic tools, they'd be far better off (and safer) paying a 'smith to do the rebarrel.

The www isn't a gunsmithing school, IMHO.

I agree with Rangr44.

If you are only doing that one barreled action, the cost of proper barrel vise and blocks, action wrench, headspace gage, and chamber reamer are prohibitive.  The only way it can be practical if you intend to do many rifles, or to rebarrel a number of surplus rifles and a barrels.  What was not mentioned is the possibilty of needing access to a lathe and the ability to use it to fit a mil surplus barrel to your action.  Paying a gunsmith to do it RIGHT is the most practical approach if you are not equipped or have the necessary skills and knowledge.
