I would start lower in charge weight for that powder.
I'm pushing 124 grain plated bullets with 3.6 grains of Titegroup at the same OAL. They cycle fine and are quarter sized group accurate.
If I can get Sunday off, I'll be taking some with me to the shoot. You'd be welcome to try them then.
Added to my note book thanks.My favorite load with Unique is:

115
1.130 OAL
and
