[QUOTE="benchracer, post: 1102359, member: 22069"] Something based on .22 TCM seems to me to be the way to go here. It easily outperforms the 5.7x28. You can make brass from cut-down .223 cases, even ones with split necks. If you start with a rifle chambered for .223, you should be able to cut off the threads and re-chamber the factory barrel for the new cartridge. Subsonic loads would be easy to produce by adapting Calhoon's Blue Dot/800-X lead bullet loads for the .223. They are easily scaled up or down and can be adapted to use non-lead bullets. [/QUOTE]
