I am shooting a .41 mag Marlin 1894 carbine. I would like to know if there is a solution to this problem. 1st shot is always 2" higher than the rest of the group. Shots 2, 3, & 4 all cluster together. Shot 5 always strikes high about 1/2 way between shot 1 and the clustered group. I have looked at my 1st targets from the past 3 years and for this firearm the results are always the same. Any idea on what is causing this or how to correct this problem? Thanks.
