I know H4831 is more temp stable, but I have found RL 22 to be more accurate in my rifles. My primary use for it is 95-100gr. .243 and 140-150gr. .270. It's a champ in both of them.
My results are like aboltfan's. I struggled to find RL22 years ago and switched to H4831 for 243, 25-06, 270 and 300WM. With availability over the past several years I's shoot whichever I could find.
