I am about to load up some 150 grn Hornady Spire Points for my Jungle Carbine and welcome advice. The use is informal paper punching at 100 yards, using iron sights. My Sierra manual lists the 150 grn accuracy load as 40.8 grns of IMR 3031, a powder I do not have. Currently I have IMR 4064, IMR 4831, IMR 4895, Varget and H380 available and hope someone has a favorite mild accurate load with these powders. Thanks for any advice.
