To Everyone who has replyed to this post.

First I would like to thank everyone for the information so far and as everyone to accept my appology for not replying sooner. Just as I hit the enter button to post my problem, my computer crashed. I did not even know if the posting was made or not. I am having to borrow a computer and will have limited access for a day or two until I can beg, borrow, or steal one as I hate to buy another one since the one that crashed is only 30 days old, been in the shop 29 of those days. And yes I am I happy camper....LOL

At any rate please bear with me and I will answer all as I can. My porblem is that I want to use a standard length action for this rifle and do not want to reload. I wish to purchase factory ammo. I have been told that the .404 Jeffery can be built on a standard length action without any problems????? I have also been told that the .416 rem. Mag. can be built on a standard length Mauser action although I find this hard to believe.

I am looking at an old Mauser in caliber 10.75x68 with a frosted barrel and a bore dia. of .425. This would be ideal if it could be converted to .404 Jeffery and the frosted barrel which is .001 larger would not hamper performance??
