OK here is what I got:
135gr fmj with 231 7.0 grain will give you 1177fps (average) 7.5 will give you 1343fps
155fr HP 231 7.3 is 1250fps 5.8 is 1000fps
180gr HP 321 5.4 is about 1000 6.2 is 1110fps (my range load if I have to use 231
200gr fmj 231 5.0 is 900 fps 5.8 1072 fps
hope this helps. this is all I have ever ran through the crony with 231. I try to use autocomp or other brands for the 10mm to get its max potential but 231 does work fine. I find it dirty though and a bit sluggish compared to say autocomp.....fire away!!
