I sighted my ML in using Powerbelt hollow point bullets. I was happy with the accuracy and the consistency. It was my first time firing a ML and it seemed straight forward enough given the info on this forum and you tube. I can't find any data on the Powerbelts that would indicate whether they're 245 gr or 290 gr. ? Anyone know how to tell? It was a used gun and the bullets were part of the deal so I'm trying to buy more bullets. I'd like to buy the same bullet.
