After test firing 5 rounds for function and checking for pressure signs, I loaded up 100 rounds with 4.1 grains of Bulleseye. After firing all 100 rounds I was consistently shooting 6 inches low at 15 yards. Seems like the load is just to light, although it does cycle my PT1911 fine. Any one else using bullseye and have a load they like? I have seen load data from 4.0 grains to 5.3 for bullseye. Think I am going to bump it up to 4.5 grains and see if I can bring my POI up some.
