I built a 16" , 8 twist, rifle length gas .264 LBC( BHW barrel) A while back, I messed around with some handloads but the barrel shot the factory Hornady 123gr A-Max and 123gr SST so well that it was less hassle to run factory ammo and open up my spare reloading time for some of my other wildcats. It shot it really well especially the 123gr factory SST loads, I'm talking always hovering around the 1/2 MOA mark if I did my part. I had a connecting where I picked up both the A-Max and SST's for 17.00 a box, well worth getting a accurate firing then having the brass. Well here's the delema, I haven't changed anything on my carbine. I got down to the last several factory boxes of Hornady 123gr SST's and decided to pick up another ten boxes. When I took the new stuff to the range I would be lucky to get a 1 1/2 group at 100 yards. Upon closer inspection of the new batch of ammo I noticed the primers were silver, instead of gold like the factory ammo I had purchased last year. I also noticed that I was piercing a primer on the new stuff with the silver primers on the average of every third round or so. So I then loaded a magazine with last years factory Hornady 123 SST's with the gold primers and shot them at 200 yards, the results were groups(3 rounds) just over a inch and no issues with the primers. Here's a pic of the case heads. The new stuff on the left and last years factory offering on the right. This is how well last years factory Hornady 123gr SST's would shoot. The new stuff with the silver primer would be lucky to make 1 1/2"

Looks like Hornady and you will have to have a talk. This is the first I've heard of the issue.

I'll have to give them a call, I know it's a ammunition issue.
