When I purchased my Ruger Hawkeye 6.5 prc eighteen months ago, l had no options but to use Hornady brass. ADG brass was unacceptable due to extreme hard bolt lift even at the lowest charges.It doesn’t show up until after 4-5 reloadings on the brass. If you run Hornady brass and get a Whidden custom die you may not have it happen at all. I’m not a big fan of Hornady brass so I’m going a different route.
That said, I must say that I have had great success with the Hornady cases. I had nothing but trouble with my Hornady 6.5 Creedmoor cases, though some of that trouble was most likely from my inexperience with handloading. I'm a much more seasoned reloader now, so I think my observations have more validity.
I have found that if I follow a set, disciplined procedure in case preparation I get good results. But, of course, that's true with any brand.
My experience with the Hornady brass has been more than acceptable.
