Hmmmm, guess not. Its that I have an Eibar gun someone cut the barrels back on so as to make it virtually useless as a bird gun but it's otherwise in excellent condition. Double lumps, crossbolt, side clips and bushed strikers. Much of the "work" done to others in converting is already there. It is a slimmer frame gun but I was thinking of sleeving her to 444Marlin. At around 10,000PSI it seems a good candidate. Anyone wish to comment now?

BTW - the figure quoted is of course breech pressure NOT chamber pressure!
