Many of the most quality guns made were made between 1900 -1935 which mean short chambers. Now you can buy modern best guns with 70mm chambers but odds are they will cost several thousands more. Much easier for me to buy a fine German bird gun with 2.5” chambers for say 3k vs a Piotti BSEE 70mm chambered equivalent for 15k. Not much difference in quality between the 2, Hence reloading room with 2.5in 12 and 16ga press and lots of supply’s. Often thought of selling 5 to buy the one but 5 is more fun!
