I have recently purchased a new Rem 700 in a 308. Has anyone ever heard of a new Rem gun being out of spec when it comes to the head space in the chamber. Reason for my question I have reloaded some new rounds for the gun and have experienced case expanding. I have also shot factory loads out of the gun and haven't observed any signs of case expanding. The rounds that I have loaded are within specs when it comes to head space of the casing. The load is 41.5 Gr of IMR 4895, with a 150 Nosler Ballistic Tip bullet. The O.A.L. is 2.800 and all of my cases fit good into a Lyman case gauge.
