I just got home from a trip to the range. I'm new to reloading and was anxious to try my first batch of 50. I loaded the 9mm with 4.5 grains of Win 231 behind Winchester 115 grain FMJ. The chart said to start with 4.3 grains with 4.8 max. A friend said it would be best to go with the 4.5 so I did that and weighed each one on a RCBS 750. I was using a Ruger SR9 which has been flawless with anything I feed it. Well, I had several fail to eject fully as the slide caught them (about 10%). The loads seemed to be very light making me think that may have caused it not to cycle fully. I went through a mag full of my friends loads with Bullseye in them. I'm not sure of the amount because he's in California right now to work the alternate shuddle landing sight. I was shooting with his wife and she didn't know. His loads were hotter (but still mild) and worked perfect as well as the couple hundred various factory loads I shot today. I'm thinking trying 4.6 grains in another 50. I figured I'd go to the best place I know of for great information. So, what do you think?
