I have a Stag model 5h upper and wasnt really all that impressed with the overall accuracy with it until I did a little research and experimenting. What I found out that with the spcII chambers a c.o.l. of 2.290-2.295 makes a world of difference. I load a Hornady 110gr BTHP with 29.0gr's of H322 and am getting about 1" groups @ 100yrds. When I set the c.o.l to 2.260 my groups open up to about 2.5". Hope this helps and check out for some great info.
