    My friend just got an MX2005 and found that the chambers were 3". Why would they have three inch chambers in a pure trap gun???

    A 2 3/4" shell is about 2 3/4" long when fired (actually slightly shorter)
    A 3" shell is about 3" long when fired (again slightly shorter)

    The chamber is marked to accommodate the open or fired length of the shell.

    O.K. So is the answer to the question that the chambers are 3'' (76mm) to accomodate a fired 2 3/4 shell? Is it done to reduce recoil or for some other reason. Must be having a senior moment.

    Probably was time to buy new reamers, and it was easier to order one set that would cover both their comp and field guns, rather than having 2 sets??

    Goldenbear, other than your statment of the obvious what does your reply have to do with the original question? "Why would they have a 3" chamber in a pure trap gun?" Seems like a good question to me. Post-2

    76 is also used to indicate a barrel length of 30 inches. HMB

    I called Perazzi California on this very question. My new MX-15 is stamped 12-76, and it does indeed have 3" chambers. The gentleman there said over 90% of all new Perazzi's shipped to the USA have 3" chambers. Only a gun built to custom configuration, (which is how he said they should be purchased) would be 2 3/4". When I mentioned I was not intending to go goose hunting with the gun, and wondered why they would do that, he said most stocking dealers request 18.7mm bores and the 3" chambers to reduce felt recoil with the handicap loads.

    I may not have bought the gun if I had realized that fact. My reasoning is if you hold most any 12 wad with the powder cup just inserted into the chamber there is about 1/8" of clearance. I just don't have the confidence that you will get consistant gas obturation. And from my somewhat limited experience along with talking with others who had extensive barrel work, few if any claim there is a measurable reduction in felt recoil. I won't argue that with barrel work patterns could go from fair to near perfect, but that's a different story.

    In Italy there is alot of chatter about lead being done away with by 2010.. My guess.. and that's all this is..Is they are prepairing for a "steel" shell that's maybe buffered..or long cushioned wad column.. I know of a few shooters that are factory sponsored to shoot steel and report feed back.. It's already been a topic of conversation..but no one knows why...
