So sitting here thinking (most times not a good thing) about reloading.
I've noticed that with stick and flake powder, there is variations in size.
Slight variation, but still it's there.
Being that it's not uniform, it would seem the charge would not be consistent.
If going by weight, you'd get a different amount or granules because of the different sizes.
If going by volume, you,d again get different amounts of granules because of the different sizes.
Friend of mines shoots a good rifle and we can't figure out why the groups vary with the same charge.
Digital scale, same lot shells and heads, same lot of primers.
Everything as much the same as he can get it to.
His is a compressed load.
I keep on telling him it the "IPT" that's the problem.
After looking at some powders, maybe not.
Any comments???
Maybe I'm just thinking bubbles.
