Hi All,
For really testing the capabilty of your rifles and loads you need to use the Master target system. With this you put two targets up one placed exactly over the other. Once sighted in and and shoot two groups onto the top target, how many in those groups is up to you but it should be 3 shot minimum. Then carefully retrieve the targets and mark the bottom one "Master" write the information about the load weather, temp etc on the top target and file them carefully away. you are done for today.
In a week or so take the Master and put a new fresh target carefully placed over the master and fire one group, then again write the info down on the top target and file them carefully away. Repeat this over a few months and you will have the true accuracy potential of your rifle and load. You will also notice how what you previously called fliers are not actually so but part of the rifles normal grouping as the filers will dissappear into the overall group on your Master target.
Have fun
