Thanks guys,
I had an email earlier asking for a price on this and how it came about. First, it aint for sale , second, I'm not doing any more of these! End of.
How it came about? well 2 things were happening around the same time.
The first was an oportunity not to be missed, 28" of .375 smoothbore for £2!! what could I say?

That was machined up and fitted into a 16mm od, steel shroud with some "packing" for a good fit.
I attached it onto my PCP QB workhorse and what a &!@@(% racket!, It had to have it's volume tamed, back to the lathe.....
Ok Thats sorted, now I started squishing and cooking lead to make pellets, There were a number of false starts on that route but with some help from my tame aerodynamics expert (Thanks Chrissy) and information from the Greenhill formula I settled on a pressed 26-28 grain, round nosed, hollow pellet with a secret

At the same time I had built a QB Deluxe in .22 for demonstartion purposes, this was hawked around the U.K. at various sales to generate interest. Good metal, shiny wood and a sweet action all contributed to the promotion, I was even talking Chrissy into letting me keep it, 'till I dropped it!!
Well the action survived but the wood suffered, scratched and cracked , you cant see it in the pics but there is a crack to the left rear of the reciever. Well I cant sell it now

Now what do I do?
Then it came to me. I didnt really want to tie up my workhorse QB with this barrel, why not drop it onto the Deluxe CO2 action with the damaged stock?

?
So that was it. a CO2 powered .375 calibre QB78 deluxe. Have a look at the comments in the China gate regarding B3 blueing and you can guess what I was doing today.
