OK here's the deal with mine. Got it to the range last Sunday and put 130 mixed factory/handloads through it. My best results came with Hornady Black 123 grain ELDM. They put all shots into a little less than two inches at 100 yards Also tried some handloaded ELDM bullets with CFE .223. Best group came in at about 1.75 with velocities near 2500 FPS on the top end. Kinda disappointing but wait for the rest. After getting home I was bothered by the difficulty I was having with the ten-round Cproducts mags. VERY difficult to insert and almost impossible to remove. Then I swapped out the upper on two of my other lowers and they worked normally. Ahha! Out of spec lower (or so I thought). Went to Academy the next day and bought a new stripped Ruger lower along with a LPK. Put it all together and tried a mag. Crap! No better than before. Decided to take a real close look at the upper and found that the front end where the mag seats seemed a little too thick. I hated to do it but I broke out the needle files and removed a tiny bit of metal in the corners. All mags seem to work normally now and it seems to feed smoother. I was having double feeds and bolt-over jams with the CP mags at the range. Also looking at the scope mount (ADM Recon) I noticed I had installed it with the front clamp over one of the anti-rotation tabs for the handguard and it was loose as a goose. Duh. Moved the scope back one notch and all is well. I feel once I get my stuff straight it will probably be a good shooter lol. Got another batch of handloads finished up with SMK's and Nosler ABLR using both TAC and CFE 223. Probably hit the range Sunday. Sorry for the long post...
