I dialed in a load for my 7mm with a 162g A-Max that likes either a 0.030" or 0.060" jump to the lands. Both of the jumps are equal on paper to the best that I can shoot and are marginally better than seating to the lands (gently touching). I have chosen the 0.060" jump.
My question is: Now that I am using 168b VLDs in the same load, should the jump be the same (0.060)? Is jump a gun nuance or a bullet nuance, perhaps a bullet-gun nuance? Will jump change with loads?
Pending answers here, I will take my small press with me to the range and see. I will seat them to the lands and try 0.030 and 0.060 from there.
It would be nice if jump was a gun thing that didn't vary much.
