Youguys think you have a hard time keeping the barrel cool. I usually only get time to shoot in the summer and the temp yesterday was 103 degrees. I didn't get to shoot but try keeping the barrel cool in those temps. I found my Omega was off by about five inches at 50 yards from summer sighting and winter (40 degrees) hunting. Ithas a tupperware stock and it moves POI every time I take it off anyway so I am working on that too.
