Just rec’d an order of the Idaho 130 Matchwinner zinc bullets and my initial testing shows outstanding 50 yard accuracy. I’m firing a S&W 986 9mm revolver fitted with a 6″ Walther .355 barrel. Have been using lead Hi-Tek bullets exclusively, but these 130 silver bullets load easier without any case distortion like you see with the Hi-Tek coated bullets. Since it is a revolver…have loaded with a slight roll crimp and have more leeway with OAL. Will need to work up a final load (NY weather permitting) but I’m already getting sub 2″ groups at 50 yards with a red dot double action.
I’ll be switching to these zinc bullets and while I don’t see any signs of zinc (leading) in the barrel now – was wondering the recommended bore cleaner to use with zinc based bullets.
If your groups Stink Load With Zinc!
