OK, I just got back from the mountains. Good news: The chrony is finicky but does work Bad news: I suck at shooting What I did differently: First, I continually stepped back from the chrony until the blast seemed not to effect the results. This happen at about 15' away. I taped a piece of cardboard to the back of the chrony as a target. Thanks Fred or Whisky or whoever suggested it, I can't remember. The cardboard was about 3" x 7". I could hardly hit the damn thing Whenever I was able to place a bullet right in the cardboard (towards the top of it) the chrony read a believable reading. Whenever I missed the cardboard the chrony read all kind of weird things from 600fps to 2000fps. I suspect what I was doing wrong before was I was not placing the bullet in the right spot. I hit the metal rods that hold up the difusers 4 times Luckily I brought lots of extras. The rounds: This time I didn't take the time to weigh each charge, I just used my RCBS Uniflow powder measure. With Unique it throws about a +.1. I also didn't weigh the bullets this time either. I did use the same brand brass, But I have no idea how many times each piece has been shot. And the results So, my 115gr plated bullets are going about 1107fps and my 124gr bullets are going about 1114fps. I feel good about sending a 115gr plated bullet 1107fps. Although 1114fps is in the acceptable range for 124gr plated bullets I feel like this is a little fast. I would like opinions on what you guys would change on these two loads. I'm thinking maybe drop the 124gr down to 5.0gr???
