Hey everyone,

Thanks for all the replies so far. The quality of advice here is great.

I will stay away from sleeves, as suggested. I had originally thought that going the "sleeved" route would prove to be the most simple, but if regulating them is going to be a bugger then a guy may as well go through the trouble of the monoblock route.

Bramble is there a link to the thread regarding your build of the 450 NE? I would love to browse through it. And my reference to velocities/pressures was only to try and illustrate that I am by no means a power/speed freak. I am content with modest bullets at modest velocities, and as such am not going to be asking "much" of this spanish SxS.

Newbie question, but what is "NFB"?

Ron, I am out in BC, working as a hunting guide of all things. PM sent.

As for the condition of the shotgun, it is basically new. The fit and finish is extremely tight, as I have a bugger of a time fitting everything together on reassembly. It is a very snug fit.

Anyways, keep the suggestions coming. Any ideas on how much a set of barrels in 450#2 barrels runs approximately?
