Have any of you tried this powder in an sml? I picked up a pound today and it is a small kernel extruded bench rest powder. It is in the middle between 4227 and 4198 on the charts. I am going to do a gr for gr chrono comparison next time out. I am going to stay (so so) low at 60gr with a 250gr sabotless bullet. I was asking about this powder because of no published data to my knowledge and the in-availability of 4198. Just trying it out as an option.
