Went to range with Dean Andrew with the same reloaded 55grn Gamekings that gave 1.5 inch higher POI. The weather was cold and the tunnel range almost freezing and using the same batch of home loads that caused me the problem 4 out of 6 back in the bull with the other 2 just off the bull. So well done the replies that stated it may have been the increase in temperature as this was found to be so.

Kind regards
