Re: 300 rum 180 tsx bullet
The bullet hitting below the bullseye with your load doesn't neccesary mean the velocity is lower than the factory loads. Do you have access to a chronograph? What type of factory ammo were you using? I can tell you that if you are shooting 100 grains of Retumbo with a 26 inch barrell you are probably approaching 3,300 FPS. If you don't have access to a chronograph do you know how to Mic the case head for expansion?
