[QUOTE="112Savage, post: 754727, member: 38801"] So, recently I purchased some winchester 7mm Mag brass because it was $8 cheaper than the un-stocked 264 WM brass. I used the Hornady head space gauge with 0.400" orifice to measure my old brass. Much to my surprise the old brass was 0.02" longer than the new 7mm Mag brass. This seems LONG to me! Solution, I partial neck sized the 7mm mag brass until it would chamber. I then checked the neck for scratch marks. I marked the scratches with a pen and partial neck sized to that length. After all of this I trimmed and fully prepped the brass and sorted until I found 20 pieces of 130.5 +/- 0.5 grains. Does this seem normal? The increase in length? The Solution? Am I going to suffer case head separation? Am I paranoid? [/QUOTE]
