I am working up a few loads for my .270. This weekend I got a great group using 140 accubonds with 53grs of H4350 with CCI large rifle primer. I don't own a Chrono yet does anyone have an idea of how fast this might be going? I have a 23" barrel. I'm thinking around 2900 fps. It doesn't list it in my manuals. Whats everyones opinion? Thanks for any replies
