I've picked up the 69gr. Sierra TMK's from Fly's Etc. in High River a couple of days ago. Proceeded with an identical load that I've used with the standard SMK's - that is 25.3 gr of Varget, BR4 primers, Lapua brass. I loaded them starting with a 0.020" jump to lands and incremental in 0.005" jump closer to lands (measured to the ogive, not the tip). My results were identical to yours elk. The 0.010" jump yielded 5 rounds touching. As I settled a bit closer to lands, the results improved. I'll shoot that same load and jump to lands at extended ranges up to 500 meters and see how it goes. But it is very promising. Your information was extremely comparable to my own results in spite of the fact that we shoot out of 2 very different firearms.
