The groups didn't matter at what time I shot them, the barrel didn't get particularly warm anyway. Used the exact se ammo, bipod and rear reat that I have always used.
Ill clean it, re set the rings to their required torque and check that the action is set in place properly.
I hope it is something simple Ive done wrong, as I have no idea what else it could be, it didn't look like I had screwed anything up with my bedding job.
