A friend told me (he liked 230 grain FMJ) he used Clay's powder he said it was very economical and he could still get 900fps. I loaded up some 230 grain fmjrn with the published 4 grains max of Clays. I could only get an avg of 662 fps on my chrony and the spent cases didn't operate the slide as forcefully as other loads. Some cases were sooty.
My friend was an accomplished reloaded. I can't ask him about this because he recently passed. I took two rounds apart and checked the charge with another scale and had a 4 grain max charge.
does my velocity seem slow with a 5 inch barrel. I medium crimped with a 1.200 COL, WLP. My friend may have used LP mag primers.
I used a new can of regular Clays, not international or universal. Any one having a Clays experience?
I've reloaded with unique with decent results. What powder do you like?
