I'm afraid that your question may be rather like asking "What is an accurate load for my Mini 14"! 9mm's vary a lot, and most are not accurate! I have a Smith 659 with a Bar Sto barrel and bushing, and it is not a target gun by any means! So, what standards of accuracy are you loking for? In addition, I have several 9mm's and the same loads do not work in both. I'm afraid that in 9mm's the old "every gun is unique" is probably true. 9mm's are supposedly .355, so try good quality jacketed bullets. You could also try lead bullets and see if it likes those. You could also slug the barrel just to make sure it is up to spec. Having done all that, you could still get mediocre accuracy (by target standards).
Sorry, Peter. (PS. I have spent many hours testing loads for my 9mm's and finally gave up!
