When a loaded AR-15 magazine is inserted and seated in the action, the cartridge alignment is such that it is more directly in line with the chamber and the feed ramps support the rest of the chambering. First, the design of the magazine provides uniform tension on the cartridge from three sides: from the bottom, and from feed lips on each side. The magazine and bolt interface in the AR-15 is simple. The design and function of the AR-15 platform perfectly offers the mechanical solution which the 243 WSSM lacked in a bolt action. 243 WSSM or Winchester Super Short Magnum – Fastest Modern Sporting Rifle Caliber I know

I think there could be wide eyed masses of semi-auto shooters waiting for a round like this that they could affordably upgrade their ARs with and have a great hunting caliber available. That just so happens to qualify the AR-15 platform actions as perfect! While long range shooters and hunters were, and are, focused on traditional ( bolt action) feed issues, the mechanical performance failings of the 243 WSSM are simply solved by introducing it into a modern sporting action. It is far more costly to design and manufacture a new receiver format than a new cartridge. Instead, they just hoped to retro fit it into existing platforms. The ammo designer probably spent a lot of time designing the round, but gun makers didn’t do enough to allow it to mechanically function. The way bolt actions operate meant there was not enough engineering put into getting that short little round keg of spitfire up and into the chamber. The performance of the cartridge wasn’t in question if it made it into the chamber and the trigger was pulled. The incredibly steep shoulders of the case from neck to fat magnum body meant it had a really hard time feeding in a bolt action platform.
The overwhelming complaint expressed about this round was how hard it fed or failed to feed. Namely, feed and function related issues. Reading through blogs, forms, and rifle owners’ comments on the 243 WSSM, they all point to one key failure. It was not originally looked at in relation to semi-autos, I think that is where 243 WSSM or Winchester Super Short Magnum shines brightest. Mechanically speaking ( read Late Breaking News (below) for detailed back story), what really torpedoed the chances of the 243 WSSM being well embraced, was how it interfaced with Bolt Action platforms. I am sure arguments can be made against this next statement, but the introduction in 2003 of the 243 WSSM ( Winchester Supper Short Magnum) gave the round about a 10% boost in key performance areas of velocity, accuracy and effective Range. Improved technology in propellants and the physics behind shorter, wider casings help boost performance. The original caliber has a heritage that makes the conversion to a Super Short Magnum seem very reasonable and, generally, a pretty good idea. In a few particular circles, it has been efficiently used as a Law Enforcement sniper caliber as well.
It was also proven as a competition caliber in long range precision shooting before more modern fads and technology started edging in on its accolades.
It is proven as a hunting caliber across North America, throughout Europe, Africa and so on. I would wager it has been used on almost every continent since its introduction in 1955. 243 caliber cartridge is a historically proven caliber. The Woes of the 243 WSSM ( which is truly ahead of its time) Nonetheless, I really hope there are some good tidbits in here that grab people’s interest.Īs importantly, am I hoping to get some attention from ammunition manufacturers on this caliber. USA -()- To begin with, there are statements in this article that are purely my own, and my opinions are obvious and blatant.
