Factory .308 Nosler Accubond Issues?

[tp308]

Yesterday I spent some time at the range checking my rifle before leaving for an elk hunt in a week. My fav cartridge is the .308 Nosler Accubond 165 grn. I've used these on deer for a number of years with good success. I noticed about half of the rds I fed my riffle resulted in a hard bolt rotation/close (it was random). I'm using an HS precision/Howa 1500... just to see if it was maybe the rifle, I checked them in my Ruger M77 when I got home, same issue. What's going on and do you think they are safe to shoot? (I didn't shoot the ones that caused a difficult bolt rotation) Thnx

I also ran some Federal Fusions and Hornady American Whitetail (both 165 grn) with zero issues

I had the same issue with Hornady 143 grain in a PRC last weekend. I havent tried them in my other PRC but will do it this weekend. Im not 100% sure but I think the brass is too long for my chamber. I havent had a chance to check it but thats my best guess.
