I loaded up some 300s with Lil Gun to test out this weekend using some Berry's 220 grain plated bullets. Using a Ruger American w/ 16" barrel, it seems like 8 grains was the most accurate and (I think?) slow enough to stay subsonic. I was using CFE BLK which ran well in the AR but seemed noisy on the bolt action. Going to load up some 190g Sub-X to test out next. What is your favorite load?
