Can a 243 be converted into a 25 Souper (i.e. 25-308) via a rebore?
Is a rebore/re-rilfe/rechamber possible to convert a 243 Win. to a 25-308 or is the only way a rebarrel?

Thanks,

I don't see why not, since a 243 is already a necked down 308 win but after the change is made the barrel may need set back and the chamber recut so it may not save any money over a rebarrel.

Yes, this should be possible. There is enough bore difference to make it feasible. Give Dan Pederson a call..l

Is the .014 difference really enough difference for a good rebore?

Yes, there is, but in reality no, there's probably not enough change to recut the bore without EXTENSIVE (and expensive) over head to make certain you are cutting a totally new bore and groove...

new barrel is cheaper

IMO it's a marginal task and financially worse.

Get a new barrel.

Well, I just called Danny at

www.cutrifle.com

He says it is not a problem going from 243 to 257 unless the 243 bore is really rough and pitted. Not a problem otherwise.

Yes, it is cheaper than rebarreling. Dan charges $265, which won't even cover a Shaw barrel job...
