Just wondering if anyone has found a load that has been found to be particularly accurate in Match grade type 9x19's. I have a US P210 and even cheap 115gr shoots great so far but wondered if as I extend the distance are there loads of known good accuracy.

Reloads too! :-)

Besides doing your own reloads and just trying and seeing then I'd say any of the atlanta arms stuff tends to always shoot very well.

115gr extreme fmj with 4.3gr bullseye is excellent for me out of my Swiss P210.

I've loaded 9MM for a variety of 9MM pistols over lots of years. It seems that each gun is almost a rule unto itself as to what load will be most accurate. One constant has been the superior performance of hollow point bullets in the 9MM. And among hollow points, the Sierra 115 grain JHP has always been a top performer....
