Set that far back i wouldnt shoot it. Bullet seated deeper than normal means a great increase in pressure. Setback and overlength is what causes kabooms with factory ammo.
I thoroughly inspect factory ammo before shooting it. QC is not great when it comes to factory loadings doesnt matter the brand. I like having control of the loading process which is a major reason i tend to avoid factory ammo unless i really need brass or get a very good deal.
