Yes Brad; I use Fed 215's with RL22,RL25,and 7828.
One 270 went from so/so to outstanding (great accuracy and low spreads)with R22 once we made the switch to the Fed 215's.It doesn't always work like that....but....
Ever since seeing that I do use them with the slower burners. H4831 does fine with std WW primers IME.
Reading back, I discovered JOC used CCI 250's with those old WW II H4831 loads.
