Thank you guys,
Curl, I love your collection. I am very fond of high quality Belgian guns, and you have a couple of very nice ones. Congratulations!
BTW, wouldn't it be easier to neck up an 8x57 to make a 9x57 rather than necking down a 444 Marlin?
500Nitro, I'll wait and see Fred's information. I might ask for your help later in the process if I think it's warranted. Thanks again for the offer.
