I am not sure about the 150g charge would not shoot in any of my guns. With 100g of T7 and H 250g SST bullet sighted dead on @ 100y it will drop 10.5 inches @ 200y.
My encore will shoot 90g of T7 with a 195g DeadCenterDuplex, and a 25ACP adaptor 2.5 inch high @ 100y, Dead on @ 150 ,3.5inch low @ 200y that's if I do my part. This load is will know on the Inline Forum and it does work very well.
