Doing some tuning on my ar at the moment and have some 77tmks on the way to try out based on their popularity on this forum. Was originally planning on loading them with imr4166 but stumbled on some rumors on various forums about lvr being a very good powder in the 223 with heavy bullets. Is anyone loading this combo? I haven’t found any good info on charge weights so I wouldn’t know where to start but I am intrigued as I have a good amount of it in hand
