I use the dot but I am varmint hunting.
For load development a corner of the box makes a great sighting point.
Once the groups are nice and tight I will move the dot onto the group.
The dot is far easier on critters.
Some of the multi-dot schemes are pretty good since it allows you to easily do hold over.
Groundhogs at 400+ yards (measured with a rangefinder) and 6mm Ram AI worked well.
For the most part you have to observe grass, trees, and crops to try and dope wind.
You usually only get one shot.
I could even swap barrels between .22 and 6mm and the POI was repeatable enough to shoot without testing.
Most of the groundhogs had been hunted enough the mere outline of a human 300 yards away sent them into their burrow.
All the BR tricks.
Panda action, fiberglass stock, pillar bedded, right bolt, left port, no ejector, tight neck, Jewel triggers down into the ounce range, higher power scopes.
I would buy a box of 1,000 shells and then sort them by neck wall thickness variation.
More uniform shells for longer range shots, more variation allowed on shorter shots.
A 'good' box netted ~900 usable cases.
