SSK 10.5 AR15 Upper COAL

Jus looking to see if there is anyone on ethis forum that has an SSK 10.5 AR15 Upper. I would like to know what there Case Over All Length is with Sierra 220 HPBT.
I was at 2.235 but saw here that some are less COAL and getting good groups.
I am getting verticle stringing 3-4" groups with H110 powder 9.1 and 9.6.
I don't know just reaching as I don't want to start jumping around for a solution when it could be the COAL.
Thank-You
