trying to tune a PCP without a chronograph is like running in circles. A chrono is about the same cost as 5 tins of pellets. That 1.5" circle isn't going to tell you what that larger TP and hammer spring did. To get the most out of your gun, it may involve just the slightest tweaks on that hammer spring. Only a chronograph, and being able to look at your shot strings will enable you to do this.
