jwp: I guess they did not have the choices back then that we have today....probably used what they thought was the hottest around. Can't really say why and JOC is long gone.
Maybe JOC living in the same town (Lewiston, Idaho) with Vernon Speer and CCI, had something to do with it.
Never had a lick of problem myself with H4831 and WW primers....even when burning 8.5-120 Staynless primers. With H4831 today I use WW STD LR primers in 270/30-06 etc, unless, as stated, I use RL22,7828,or RL25 in the 270 Winchester and then use Fed 215....they just work and accuracy is not a problem.
