FB: Has that load been doing well in one rifle or more than one?
Just like Roy is saying, I can tell ya that RL 7 works real well in that 17 Fireball case, and it always works real well in a 223 case.. I use to use RL 7 a lot, when it was readily available. Availability wasn't what it use to be, after Obummer got into office, so I switched over to Blue Dot and IMR 4198..
If availability was there, I'd use RL 7 more often than IMR 4198, and 4198 is a powder I use a lot of.. Just RL 7 is more of a good thing. Its not just a Fireball case thing.
I use it a lot in the 22.250 also...
