Have a new NOE 160 grain gas check boolit mold, Al called it a bore rider. Using new Starline brass, WLR primers. I have on hand H4198, RL7 and IMR3031. Found a H4198 load from a reliable source and would like to also find proven, safe loads for RL7 and IMR 3031 as well. Looking for 2000ft/sec. in the SKS.
