I have a Kimber 8400 in 338 Win Mag that will need it's 3rd barrel in the near future. I regularly shoot the rifle out to 1000y but I know there are better long range options out there. The rifle will be used for some long range shooting and culling. I would still like to carry the rifle around, but it does not need to be 'light weight'.

I would like to rechamber to something .30 or 7mm. If I can keep the same mag box and case head diameter it would be a big plus. If I can get something with a 'reasonably' short case to enable me to seat bullets long it would also be great. I was thinking of a 308 Norma Mag but would like to weigh up all other options.

I would appreciate any info, thanks.
