Well I know what it costs to put a 577 NfB together on a Shotgun action (refer the 577 Light Nitro that Marrakai has written about on his web site and on here) and that was built
on a Aus $400 Greener Empire shotgun action and the thing still cost more than a few thousand to build, regulate etc etc.

600 Nitro barrels don't come cheap (does anything over .510 come cheap nowadays).

I just find $2500 and unbelievable price, that's all.

And as someone pointed out, a 600 Nitro double that comes off the face after 60 rounds isn't any use to anyone.

bwana
the calibres you have listed are pretty hot calibres
- 375H&H, 458 ???? OR are they generic calibres for the 375 and 450 flanged versions ?
