I finally got my CLE Bartlein 223 AR build done and 125rd down the barrel so I could get on to load development. While the barrel shot some tight groups during the initial 125rd break in, it has really settled in nicely and sped up roughly 60fps once it got over 120rd. Today I shot load OCW tests with the 73 ELD-M with Varget, TAC and 8208XBR. 8208XBR continues to be the winner with every precision AR barrel I test. A combination of speed, accuracy and SD's top every other powder I test. Here's the build info and OCW tests:
