This question is aimed at 50driver. I am planning on building a rifle in the above calibre. I am in Australia, there is a gunsmith in SA that has a 375 Chey-Tac, on an unkown action(to me). Is this cartridge the same as your design? My question is this; what would the best action to use be for this type of build? I would prefer to have the rifle built by you, but I don't know how I would go getting one of your custom guns in the country here.Have imported other 'factory' rifles before, but not custom guns from 'small' gunsmiths. (We have to have a 'genuine reason' over here, and an agent to import.) I know this forum is for general questions, but I would like an answer from 50driver, any info he (or others) can give me will be greatly appreciated! If you would prefer that I PM 50driver with details, please let me know. Thanks immensely guys! Cheers. gun) MagnumManiac.
