Thanks all for the replies. @Mike D Texas , what are your SAUM brass measurements before and after sizing?
Here’s a quick rundown on what I’m seeing for an average measurements just below the pressure ring, around .250 up from the bottom. Measured with a blade mic:
New brass: .5453
1x Fired: .5479-.5492, depending on the charge.
2x Fired: .5498-.5500
The 2x loads were 57.0 gr of H4350 & 145gr Hammer Hunter Tipped, shot on a hot day, 20” barrel, avg Vel of 3025. With the heat, they may have been a little on the hot side, but other than the clickers, no obvious signs of high pressure.
My Redding FL Sizing die isn’t sizing the .200-.400 area much, if at all. It must be sizing a little (.0005ish) because the fired brass is a tight fit at the top end of the bolt throw, but sized (empty) brass chambers and extracts easily.
I colored up a 2x piece with a Sharpie that is stiff on extraction, and it seems to be contacting the chamber because the color is scraped off around .350-.400 from the base.
Does this track with your experience on clickers? Any thoughts on if I’m going down the right path? Thanks all for the help!
