Has anyone rechambered their own rifle with out any problems. Or is it wise to let a gunsmith handle this project?
If you did it yourself, are you required to remove the barrel?
Thanks

P.S. My project is to rechamber a .458 Win Mag to the .458 Lott

Steve,

Without any knowledge of your skills or available equipment/tools yours is a pretty hard question to answer.

My first response would normally be, if you have to ask the question you probably shouldn’t be doing it yourself.

If I were to attempt a rechamber/rebarrel by myself it would be like asking my wife to work on my transmission. Wrong person for the job.

I would pay a 'smith to get it done right the first time.

The exception would be rebarreling a Savage with the barrel nut. With the proper tools and equipment even a blockhead such as myself could rebarrel a Savage.

This is my opinion. Your opinion may vary.

without a lathe, the answer is almost universally don't do it yourself. some of the rare exceptions are changing to an ackley improved chamber where only the shoulder is being recut. otherwise you've nothing to guide the reamer. but even in the impvd chambers they're usually blown out and you're back to "don't".

Chambering a barrel isn’t voo-doo or anything requiring a master machinist or a degree in engineering...but it does require a good understanding of the process and the use of reamers (or more properly forming tools) as opposed to drill bits.

Your pet rifle, however, is not the best place to start your learning experience.

You need a good metal cutting lathe and basic to advanced machinist skills and tools.

You either know how to do it, are willing to learn from someone that does or you take it to someone that is qualified.

i agree completely there isn't any great mystery around chambering or any other gunsmithing work and have cut quite a few perfectly acceptable chambers. please note however, the posters original question was not chambering a barrel. it was RE-CHAMBERING. quite another matter. run a 300winmag reamer into a 30-06 w/o a lathe and see what you get.

WillMcKee, re=chamber to an AI without setting the barrel back and see what you get.
