Have any other members spent any time conducting accuracy tests at higher velocities (2500+) using different PC methods as the input variable?
I've been tinkering w/ 3k+ loads...playing around with different PC application (static gun, shake n bake, dip and cook, etc) as well as different cook methods (stood up and laying flat mostly) to see what, if any, impact they have on high velocity loads.
Interestingly enuf (purely anecdotal at this point) bullets that were cured lying flat seem to be more consistent than bullets that were cured standing. Application method hasn't appeared to be a big factor that I can tell (haven't tried acetone or solvents yet)
Educated guess:
* Standing the bullets slumps the paint toward the base and creates a bullet profile that increases the taper from tip to base (ever so slightly), taking the bullet out of its designed profile.
* Laying them flat allows the paint to flow over the bullets more or less with the same thickness across its entire surface. Eg- no top-to-bottom taper increase.
I've not noticed anything like this in my 9mm loads. They've always grouped the same no matter what I do, but 1k fps is a far cry from 3k fps.
Thoughts?
