I bought 115, remington FMJ, UMC from Dicks Sporting goods. The only failure I have had was due to a cracked mag that put the nose too high and it jammed in the ramp, right side. No failures to fire what so ever.
Prior to Dec 1, you could buy by the case, of 10, 50 rd, for 6.98 per 50.
After Dec 1 it jumped to 8.98 for case lots of 10, 50 rds.
I also picked up a couple boxes of Wolf 124, to see if the heavier would shoot higher, as I was shooting very low. The 124 did actually fire a little higher at the same distance. I have had no problems with the Wolf Steel cases.
