I loaded some last night with 43 grains of 4064 IMR and they are very compressed loads. I set my die to roll a little bit into the canalure. I shot them today in the nasty wind and had 2.75" group at 100 yds with the open sights. The target was held up by a 5" fence post and the three shots completely destroyed the post, cut it right off. I was impressed.
