I've had the opportunity to shoot a few Contenders over the years from 22LR thru some custom long-range cartridges, but I've never owned one. Now I am getting the itch to add a T/C to the accumulation.

Is there a summary or list of cartridges the original Contender frame will safely handle? I like the old originals and would like to stick with those if at possible and if it make sense to do so.
My initial thought is 22 barrel, 223 and very likely 30-30.

However, I've got a 2-gallon bucket full of 300 Savage brass that needs a mission:)

Can the Contender house the 300? Also wondering about 6.5 Creedmore.

Thanks for any info you guys have.

Randy
