Last trip to the range I thought I would try some of the Hornady that I had picked up when I first bought my 5r. I had fired half of the box months ago with no problems. This time 3 out of 5 rounds would lock up the bolt after fired. I would have to get up out of position hold the rifle tight with my off hand and slam up on the bolt handle to break it loose. I ran some FGMM through it, as this is what I usually shoot, and it cycled fine. I loaded 5 more Hornady and again 3 of the 5 jammed the bolt closed.I ran FGMM through it the rest of the day with no problem. Needless to say I won't be using that ammo again, but is there something I should look into? Is this common with 700s?
