I have a slightly different perspective. When I went to Wyoming for a PD shoot we went thru 250 to 300 rds per day.
95% of the shots were less than 200 yds.
On top of this there was the constant wind and the need to hold into the wind for each shot if the range was beyond 150 yds.
Because of this, a basic 10 shot 3/4 moa load was more than sufficient.
With that in mind, and since I was loading for two shooters for a 3 day shoot, I loaded up 1,800 rds.
I used Surplus 5.56 LC brass, Remington 52gr HP bullets, Benchmark Powder, and Remington Benchrest Primers. The loads were economical and the performance on PD's was fantastic (2 ft of air no problem).
If you are looking for lower volume shooting scenarios then go with the high grade reloading components.
I have yet to try my PD load on a Coyote. I stopped and looked at Sierra 45 gr Blitz bullets today and thought very seriously about purchasing them.
