38 Super and 10mm loads

[sdmc530]

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!!

Thanks
So is 6.2 pretty much the limit using 231 in a Dan Wesson supported chamber?
Hodgdon tops out at 5.8 with 180 gr fmj's at about 1061 I think, but I suspected it can be higher when using a supported ramped barrel like the Silverback.

Ummmm well I use my high power loads for hunting in my Glock but that is with an aftermarket barrel too. However I used them in my Colt Delta and had no issues fwiw

I will see how these do.
I will use TightGroup on the next batch if it ever gets here
