I know this has been discussed before, and seems it really doesn't matter all that much.
But I just had to find out for myself.
I've always thought that if I could get them all about the same weight, consistency would be better.
Friend got me a cheap chinese digital scale.
I weighed a bunch of 309/160gr.
Never got close to 160gr.
Varied from 151gr to 155gr.
I sorted it down to closest to 154gr.
I'll see how they shoot tomorrow.
