I am shooting my 10t-sr in 6.5 creedmoor. I shot a 14 round string of 147gr eld match and 143gr eldx. first 5 shots were the 147 and had a good 1" group at 100 with a few fliers. then 5 of the eldx which shot a lot worse, 1.5-2" then 4 of the match ammo. after about the 12th shot i noticed a lot of smoke coming out. it didn't really smell funny but was odd. these shots made 40 total for the rifle. I cleaned it real good with clp brushed and wiped out when i first got it and have shot 10-12 round sessions with running a dry bore snake after each session. so this was maybe my 4th shooting session with it. all 14 shots were at a slow pace, taking time in between groups to reload my mag. the barrel was hot to the touch. I retrieved my target and shot a temp gun at the barrel right in front of throat and it was 118 degrees so i don't think it was too hot. anyways im thinking it was maybe the powder fouling causing all the smoke? I don't know, what do ya'll think?
