I was looking at my old thread http://www.thehighroad.org/showthread.php?t=619769 about 38 Special, and I recently did some testing with some new ammo I made up on my 1050. I am using Redding Competition Pro dies, CCI SP, Bullseye, Dardas 126gr LSWC bullets, and I shot them through an M&P9c and my S&W 952. I ran 3.8 gr and 4.0 gr loads.
Interesting results. I shot 25 round sample sizes. In the M&P9c everything had higher SD, (11.5 vs 9.5 for FC headstamp), and 11.6 vs 9.6 for Mixed headstamp. I guess these aren't likely to be significant unless you're shooting 50yd bullseye, which I'm not. And dropping the powder to the 3.8 gr load lowered velocity from 1116 to 1082, but dropped the SD from 9.5 to 8.8.
Since I don't have a Ransom rest set up to test at 50 yds, it's unclear if any of these actually shot better on target than the others.
My conclusions so far:
1) I guess it doesn't really matter to sort by headstamp as long as I can run them all through the reloading machine. The 1050 swaged, sized, and did it's best, so no problems there.
2) Shooting a better gun gets better results
3) Bullseye powder meters and shoots well, and is worth wiping the extra filth off
Am I missing anything?
