This 308 keeps getting better.I had someIMR4320 that I had had for probably over 10 years,so decided to try it with a130 gr hornady SP.It shot 2 in one hole and one almost touching at 100 yds.Tried 3 at 300 and it was almost a one holer also.The more I shoot this thing the more I like.I measured .410 with this group.
