135gr is an odd weight for the 9mm and I would do as suggested with adopting a mid load between most published information....
You might also want to look for some Ramshot Silhouette powdeer...that's what I use in my 9mm, .40s, and 10mms..The 9mms take 5.1gr for a really accurate load for my Sig, using a 115gr bullet..
I'm just guessing, but with 135gr, you will probably come in with a 4.7-4.9gr powder weight..If you work them up from a lower starting charge level...
