I'm converting my remmy 375 H&H to take 338 lapua AI magnum mags via a base conversion kit. Three in the box plus one just seems too few. The fitting is an arse for this kit!!!
It's just a **** of a job. 'some inletting may be required' is just not quite a full enough description of the work involved to fit the base. 2 hours at work with all the tooling you need and I'm only half way there.
Best advice.... get someone else to do it !
Any one else had one done? I know it will work out sweet but I'm not used to working hard at work.
