Hello Long Range Hunting forum community. I love to handload and would classify myself as and advanced intermediate loader (I measure from the datum point on the shoulder, etc.). I currently successfully load .223, 6.5 Creedmoor and 30-06 in bottlenecked rifle cartridges and .350 Legend and a bunch of pistol calibers in straight walls. I rarely buy commercial ammunition, and usually when I buy a new caliber gun, I buy the dies and once fired brass for it. This has been very successful and enjoyable for me.
Here is my problem, I recently bought a Winchester Model 70 super grade in .270 Win. I bought some once fired .270 brass from Diamond K Brass LLC out of Phoenix. The rounds that I was successfully able to resize require inordinate about of effort and force. Several cases have stuck in both the die and the expander ball, which only happened once before on a 30-06 case years ago. I sent the sizing die back to Hornady and they checked the dimensions and gave it a polish. Once I received it back I lubed a case with One Shot, let it dry and the case immediately stuck in the die.
I called Hornady and they assured my my die is in spec. They said the case may be blown out of dimensions. I do see round marks from both the Remington and Winchester brass from the pressure gauge. Has anyone encountered this problem before?
