I love your VV 3n37 data. I was wondering if your BarSto barrel was 4.6'' or if it was longer? I am trying to develop a new load with 3n37, and I am using a stock barrel. I am just looking to get to 1150 fps with CCI 300 primers, 180gr Jacketed HP's and new Starline brass. All the different manuals have such different info, it is kinda hard to lock down a good starting point. I have been reloading for a few years, and I am not a beginner, but just looking for somebody that has some real world info. I appreciate any help you may be able to lend me.
