I just picked up some Clay's and read through all the "Verboten!" posts on Clay's and .40 cal.
Clearly, the 10mm case is much stronger and OAL much longer than a .40 load. I'm wondering if that would reduce the possibility of a "kaboom".
I quickly did up a minor pin load, that seems to work well:
W231 4.8 gr., 180 gr. Berries, 1.255 OAL, should be about 890 fps. Haven't chrono'd it yet. Worked real good on the pins and seems to shoot accurate to 10 yards. Mild recoil, relatively clean (for 231...).
I'd like to work up a minor load for 200 gr. using Clay's. Minor for pins means just under 165, not 140ish.
From what I've read and the tables I've looked at, looks like around 3.5 gr. is a good starting point.
Thoughts?
Yeah, I know not a whole lot of guys here shooting 10mm....
