I tried RL23 in my 280AI last year. I got sticky bolts on every charge. I thought it been have been some of the brass, or the maybe something about how the die was set. When back to H4831 no sticky bolt, OK I know I have good brass (Nosler) and the dies are set good, I went back the RL23 again -->> sticky bolt again. Shot some RL22 with good velocity and good groups but I'm wanting a powder more temp stable.
Recently bought some Rl26 and H1000 to try. I see a few folks have had success with them.
