Bumping up to ask if anyone is having luck with rl23? Gonna do a improved version for a hunting gun and have a pile of rl 23. Plan on using 175 ablr since I've seen good precision and terminal performance from several friends.

I'm running 58.5g RL23 with 183 SMK out of a 29" 1:8t barrel. Getting 2995 fps, with SD below 7. At 59+ grains I start getting heavy bolt lift then clickers. I've gone up to 60.8 RL23 with the 183 SMKs and got 3088 but heavy bolt and clickers pushed me back down to 58.5g.
