[QUOTE="Kansaswoodguy, post: 1099575, member: 83267"] I played around with it a little more today with one of my other AR's no better than my first attempt to be sure. I'm going to have to invest in a Geissese trigger for at least one of my lowers to really see what the uppers can do. I was fighting the mil spec trigger pretty bad today the one on my WOA that I used today is even a little less predicable than the one I used yesterday. That putting 5 five shot groups on one sheet of paper is the a&@ kicker. In the groups I shot yesterday I had one group at .390" that in itself was not to bad but when you add all eight of my groups together and take the average I was shooting right around .75 MOA. Since we are talking extreme accuracy out of gas guns any one turning their case necks. I've been thinking about it but am trying to quantify what sort of reduction in group size it has. I understand that for the benchrest guys .01" could mean the difference in a win and makes it well worth the effort for them but what sort of reduction in group size does it make in MOA on average? Everything else being equal. As for runout what sort of group size reduction do feel you get from culling the ones over .002. I use the Redding competition seating die and don't think I have to much runout but I do not own a gauge to check runout maybe it's worth it also. Here is a photo of a 5 shot group at 400 yards with the 75 gr HPBT Hornadys [/QUOTE]
