[QUOTE="dennishoddy, post: 2971821, member: 5412"] My .243WSSM is a short action cartridge that makes it ideal for the AR-15 platform. There are some mods that have to be made to the upper. The parent case is a .404 Jeffery, so a different BCG must be built, and a dust cover can't be used as the ejection port has to be opened up a tad for the fat cartridge. The performance is only slightly better than the standard long action .243. 100fps faster, maybe. A lot of the internet resources are just research, and not actual bench time. Mine is a 1-8 twist AR that will shoot Speer 100 grain BTSP into connecting groups at over 3200 fps at 100 yds. Using the 55 grain that runs 4050 fps in the 1-8 will result in pie plate groups. It needs a 1-10, maybe 1-9 to get any accuracy. [URL]http://www.gunnersden.com/index.htm.243-wssm.html[/URL] [/QUOTE]
