Hello All, I am looking for people who have tried this and wanting there input in regards to load data, velocity and accuracy? I have 22" 1-10 twist heavy varmint krieger 5R barrel here not being used, a trued Rem 700 action with bushed firing pin in a HS precision tactical stock fitted with jewel trigger and Leupold 6.5-20x50 scope that is not being used. What i am intending to do is fit this barrel to this action and chamber it for .30 BR. Running Quick load it looks like i should be able to get about 2500 fps with the 155gr bulles using H4198, at this speed the 155gr berger fullbore bullet reached 750m before dropping below mach 1.1 The idea with this combination is to punch paper out to 600m to get trigger time up without costing myself to much in doing so and get extremely long barrel life. re Sam.
