Every other lil gun load I've used loaded the same has been extremely accurate.... Lil gun with a 200 ftx at that range would do 1/4 inch or better 5 shot groups so I can't see it changing that much.... I have however had eandom stringing here and there with the 357 max barrel and I'm thinking it could likely be traced to an inconsistent rest applying varying amounts of pressure to the gun and my hands exacerbated by how very light the thing is... Safety wise I'm well under what could be considered dangerous that I am sure of and my experience with lil gun is that it likes fairly hot loads best.
