Yea good luck trying to find H-870 that stuff dried up awile ago around here and it shot great in my 300 rum too. That WC872 sounds good 8lb's for 40 bucks can't beat that for rounds that suck up a 100gr+ of powder every time you squeeze the trigger.I dont get to many rounds out of a 1.lb of Retumbo and it cost a lot. Does anyone have any experince with it how does it shoot? How would it compair to Retumbo slower or faster? Is it temp Sensitive?
