[QUOTE="Toydy, post: 1323344, member: 91126"] So I'm shooting groups at near maximum load and seem to be noticing a pattern. I'm shooting a 270 wsm with 130 gn ttsx at around 3220fps and testing by shooting 3 shot groups. The first 2 shots of the group are nearly touching but the 3rd is high by around 3/4 to an inch. Could the barrel (sporter profile around 17mm at the muzzle ) be heating up by the 3rd shot and be the problem or could it be something else ?? [/QUOTE]
