+1, unless your shooting archery equipment with $15.00 arrows!I find a bullet/powder combo that groups well, loaded to SAAMI overall length. From there, I head for the lands in .005" increments and look for a sweet spot. Heck, that's the fun of reloading. I know, I know...it's just a hunting rifle, but no such thing as a group too tight.
Sometimes +/- ?I am refering to hunting rifles. Once you find an accurate load you are happy with [hunting ammo], do you experiment with seating depth to tighten the groups?
