can anyone help. i zerod my 270 with t8 mod one zeroed i done 4-5 groups removing t8 in between groups to let barrel cool and rifle shooting great. at home i take the t8 off and clean the rifle i take the rear bush out off t8 and grease the thread and put it back in. on going back to the target i find the rifle shooting 6 clicks to the right has anyone got any thoughts, scope is tight the only thing i can think of is the removel and refitting of the rear bush but surely not.
 
I presume the plastic rear bush is touching the barrel.
It should not touch the barrel once the moderator is tightened.
If it does, just get it bored out to a slightly larger diameter.
