Guns and Ammo reviewed this Benelli and this is what they had to say: The Benelli Super Black Eagle II has earned an enviable reputation since its introduction. This unique semiautomatic has a minimum number of parts, contributing to its remarkable functional reliability and ease of maintenance.
The heart of its design is its sophisticated, yet simple inertia system. The bolt has a rotating head that has two locking lugs. When the gun is fired, recoil moves the inert breech bolt forward about .16 inch, and that compresses the inertia spring between the bolt head and the bolt proper.Compression of this spring overcomes the inertia of the bolt and forces the bolt backward. At the end of its travel, the fired case is ejected and the hammer is cocked. The slight delay of the start of bolt travel allows the shot to exit the barrel and pressure to drop. It’s significant that this feature also allows the use of a wide variety of loads without adjustment. The SBE II digests virtually all standard 2¾-inch 12-gauge loads, plus 3- and 3½-inch magnums. After ejection, a spring in the buttstock shoves the bolt forward, picking up and chambering another cartridge in the conventional manner.The chrome-lined barrels of all Benelli shotguns are proof-tested in Brescia, Italy, to a pressure of 19,571 psi (at mean sea level). This is roughly double the pressure of shotshells, so it provides an ample safety margin.A new SBE II variant, the Benelli Performance Shop SBE II Turkey Edition, has about every nuance any dyed-in-the-wool gobbler hunter could want.
