Unless you are using the EXACT 230gr FMJ, then your OAL is TOO short. Hogdon uses the Hornady TCFMJ, it will seat shorter than the 230gr RNFMJ. Clays is a touchy powder, unstable as you aproach the top end. The pressure curve goes vertical as you cross max. Seating too short will increase pressures, so ALWAYS load to the longest OAL your gun will run with, regardless of the data. OAL is ALWAYS gun & bullet specific.:shock:ok i am a new reloader. i am working up a load with clays under an h&m 230gr fmj. at 1.200 oal. i started at 3.7 but wound up at 4.0 gr. which according to hogdon is max load. so far the brass looks good and no noticeable signs of pressure. recoil is so smooth and have yet to properly test accuracy. the oal on hogdon site was 1.200. my question is i want to increase this and use the same load to test for accuracy. i have loaded 3 at 1.200, 3 at 1.215, 3 at 1.235, 3 at 1.255, and 3 at 1.275. can some one educate me as to how the oal will affect my load pressure etc. suggestions? so far my max load at 4.o gr clays under 230gr fmj oal of 1.200" is shooting 735fps to 745fps.
That is an extremely light load, surprised it runs the gun, maybe 700fps?Loaded up my first bullets ever the other day and finally got to shoot them yesterday. I was incredibly happy with the results. Recoil was very much reduced and the gun cycled flawlessly through 2) 10 round magazines
Mixed range brass, some small primer and large primer
Winchester large primers CCI small primers
230gr lucky 13 cast lead
I was looking for a load for shooting USPSA. I may have found a winner the first go around. I tested them on an 8" plate at about 50' and they all made some noise. These were shot from an HK45c so a 3.8" barrel. I can't wait to load some for my xdm9 5.25. Very excited to be reloading
