I have been fighting a 243 here for some time and have done all the ussual mods-trigger, O-ring, lapping, in an effort to get my 243 to shoot. I took it to the range today and what I ended up with is very odd to me. Let me first say I was extra carefull to follow through with my trigger pull. I fired 7 shots the first was 4" low and 1" left, the next 2" low 1/2"left the third was 1/4" low and 1/4" right heres where it gets weird. I ended up with three very sweet groups in very differant places. With the same POA, I got a .75" 3 shot group within an inch of POA, a .3" 2 shot group 2" low of POA and a .25" 2 shot group at 4" low of POA. only 2 shots in the same group were fired back to back the rest were random. so barrel heat up wasnt causing stringing. the first and last shots were 4" low and the rest were randomly 1/4/" to 2" low. I'm convinced its me but dont know why. any thoughts would be apreciated.
