Gunsmithing Which calibers are interchangeable merely by re-barreling a 308 Winchester bolt action rifle?

[want2learn]

Hi, i have a 308 Winchester bolt action rifle (Sig SSG3000).

I'd like to change the caliber to something more forgiving. I've received a lot of great information from the members of the forum....calibers such as the various 6mm derivatives such as the 6BRA, 6 Dasher, 6 Creedmoor, 6.5 Creedmoor among other options.

I forgot however to ask which would be easy to effect , merely by changing the barrel, keeping the bolt and magazine the same and not having to use a flame or hot salt or lead to mold cases.

I'm hoping to improve my current format to facilitate accurate long distance shooting while affording less recoil. thanks

6.5 or 6 mm creed would be my first choices in that order

 

[strike33]

6.5 creed, 6 creed, 243, 7mm-08, and many-many more

Any short action cartridge, i would assume.

6.5 Creedmoor or .260 Rem would be the choice for many...but I'm a big 7mm fanboy... had the 7-08 out yesterday ringing steel with boring regularity at 656 yards. BUT...for reduced recoil, consider the 6BR (or Dasher).... Recoil chart:

thanks, I've been strongly considering the 6 Dasher but not sure if my magazine would feed it reliably...I did see that Grafs has cases available for reloading

There are a few mag inserts that should help with the feeding of the br sized cases in aics mags. Primal rights and PVA are the two that come to mind

thanks..unfortunately the Sig SSG3000 has what i believe to be a proprietary magazine...i don't think it's a AICS mag (wish it were)
