    Whats your definition of a "modern round"? This round was created to fill a supposed gap in ballistics that ultimately does no better than the "modern rounds" out there. Theres a lot of opinions on this round and a lot of criticism.

    The .40 S&W (10×22mm Smith & Wesson) is a rimless pistol cartridge developed jointly by major American firearms manufacturers Smith & Wesson andWinchester.[3] The .40 S&W was developed from the ground up as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9mm size) automatic handguns. It uses .40 inch (10.16mm) diameter bullets ranging in weight from 105 to 200 grains
    History[edit]

    In the aftermath of the 1986 FBI Miami shootout, the FBI started the process of testing 9mm and .45 ACP ammunition in preparation to replace its standard issue revolver with a semi-automatic pistol. The semi-automatic pistol offered two advantages over the revolver: 1) it offered increased ammunition capacity, and 2) it was easier to reload during a firefight. The FBI was satisfied with the performance of its .38 Special +P 158 gr (10.2 g) L.S.W.C.H.P. (lead semi-wadcutter hollowpoint) cartridge ("FBI Load") based on decades of dependable performance. Ammunition for the new semi-automatic pistol had to deliver terminal performance equal or superior to the .38 Special FBI Load. The FBI developed a series of practically oriented tests involving eight test events that reasonably represented the kinds of situations that FBI agents commonly encounter in shooting incidents.

    Thanks lol i was too busy cleaning up my backyard to respond.

    As for the second part, a modern round is any new ammo. Advances in quality control, ballistics, gunpowder and computer technology have made the ammunition much more reliable than it was even 10 years ago.
