Does anyone have any info on a ssk rebarrel on a model 71 win in 450 alaskan , i have fired brass for chamber measurements and i think i have a ptg reamered 450/348 alaskan ackley improved , looks like my rcbs dies arent going to work with this chamber , any info would be greatly appreciated! Trying to find the right dies.

you might need to send some fire cases from this rifle if possible to Whidden gunworks they make dies or call them ?

Thanks pete , yup did talk to him also, good people , hornady was the most reasonable so far though

Whidden makes much better dies but there is an expense to it also. good luck with this project,Pete53
