Take it to your smith and get his oppenion, I would guess that the action is good, but I haven`t seen it. As for your question about what round to go with, you can go with any round with a .473 head and not have to do bolt work. I just got a .35 Whelen barrel for a Mauser action about 5 mins. ago from UPS that`s going on a CZ-24 action. Mid -Way has some short chambered barrel on sale at very cheap prices now. I can`t swear their top shelf barrels, but for the price I`m going to try one.
