Sierra 107 TMK Load Data

[Brado16]

Do the 107s like or need a decent jump? Just got my hands on some, and a loaded Dummy round loaded to the lands is 2.9150” in my rifle, but my MDT mags are limited to 2.85”. If I load them to 2.80”, that’s 0.115” jump. Any input?

My Tikka did not like them at 2.8”.

My post a recently with a 1.1” group was shot from a 243 with a COAL of about 2.820 and an estimated jump of about 0.025”. Best group I’ve shot from this gun so far and I have no plans to mess with it.
