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.
180 is the lightest I've ever shot since it was rechambered the 200 ftx was extremely accurate but only out to 50 yards..... I just don't have the twist rate to stabilize it any farther out unfortunately.... Every load I have put through this gun has had some stringing at one point or another though and all I can come up with is I haven't always had a good consistent rest and since the little booger is a handful I think in trying to not send it flying backwards over my head again I might bear down a little on it which is what I believe causes stringing when I have a poor rest.
