Looking at casting some 230gr 309 projectiles for 300 BlackOut. Was planning on running them through a supressed SBR AR. The AR gas system is pretty simple and easy to clean if needed should I encounter leading, but running these subsonic I don't know that it will be an issue, or is it? Thats my question.
Anyone shoot cast bullets through an AR? Any problems or concerns encountered?
