North Texas ED.,
I agree with you and others about the romance of the 577/450. I lust after one each time I watch "Zulu". But your right, the expense of brass, dies, etc. has put me off. The beauty of the .303 is partly the convenience of having components on hand.
I think I messed up at the very start of this posting, I think its SOG that has these carbines I'm refering to. Anyway, I eargerly await you comments once you have one of these guns in hand.
