I'm set pretty good on 2F but would like to get one pound of 4f for the rock lock to try out. I've been using 2f and is working fine, just want to try some 4f because why not. . I get my powder from Powder Valley , reasonable shipping and Hazmat, plus there in no minimum order. Back in the spring they said they were expecting a shipment in May/June and we're half way through July. Any word when the next boat arrives ? -Thanks
