What i have found that once a load is developed at 100 yards to most deffinately move to 200 and 300 yards. This where I do my tuning. The last thing I do is change to differant primers.
I propably do things a little different than most as I look to drive a particular bullet in a given caliber at a specific velocity to attain the performance I demand from my cartridges w/sub MOA accuracy.
I think the variance of powder charges must be within acouple of kernnals at the upper level of velocities. Which I think where the harmonics are definately much more in play with lightwieght hunting barrels.
EVERY charge is weighted to the exact, overall lenght is exact, and runnout is within .0015.
I want every advatage in my favor for my shot. Pretty particular for factory chambers... the same set-up as my customs. A given rifle is only as accurate as the best ammo available.
Keep weighing every charge Evan.
