Who paper tunes????

I usually do a walk-back, make sure my rest is centered, then throw on some BH's and shoot them to make sure they shoot close to my FP's, tinker ever so much, and get them tight, from there, I'm usually ok.

If you paper tune, then have to move anything to get your BH's to hit with your FP's, what's the use in paper tuning in the first place???
