[QUOTE="Jakeweb09, post: 1941474, member: 113122"] thats definitely interesting. As the proven load the smith gave me with the gun was a shade under what was working in my work up. Pretty sure he was using Norma brass so with ADG I expected the opposite. With the load he gave me though I am shooting the exact velocities he had. (Within 10fps). I will be pulling the firing pin before bumping back the brass and feeling how they chamber. And to LRnut I’ve always loaded mellow rounds with unfired brass and then measured the shoulders. Similar to the way you would do it if sending brass to Redding for custom dies. However I think the brass didn’t fully expand on first firing. New brass measured 1.6245 with the Hornady tool. Then first firing it all measured to 1.6265. Bumped back to 1.6255, and second firing it measured 1.6285. So it clearly expanded more the second firing. While gauges will probably be more accurate and I’m probably gonna order some tonight. I’ve had great success sizing .001 back from my fired cases. And the fired cases in my other rifles have always measured consistent. However I have always used Peterson brass and this is the first time with ADG, so maybe it’s just harder brass and takes a bit more to stretch to full length? [/QUOTE]
