All the driving ranges up here have been closed due to the snow and cold. I’m not the best shot but come warm weather, I like to at least hit it straight and long when I get out on the course. So long as I don’t embarrass myself on the first shot, I can just lob it onto the green from there and take four or five strokes, if I need them, to finish the hole.
I zero my AR15 at 25 yards which also zeros at 200. Still gives me a tight head shot at 100 yards. Good enough for an old guy using a good red dot.
With the AK, I use iron sights and am content to keep 100% of shots inside an 8” target at 100 yards.
Before anyone poo poos this, realize that I am not shooting from a bench.
From my breakfast porch through the kitchen and laundry room, out into the garage, I can get fifteen yards to the rubber mulch 4 x 5 bin I built for an indoor shooting range backstop. A cat litter plastic bucket filled with rubber mulch laid length-wise holds the targets. That eighteen inches of mulch will stop anything up to but not as much as a 5.56. I calibrate using a twenty-two LR conversion kit.
Here’s a ballistic calculator that well help figure what you need at 15 yards

Worth a try ping
I’ve been using one of the SiteLite laser boresighters. You enter info such as caliber, bullet weight (and ballistic coefficient if you have it), velocity, and distance at which you want it zeroed. It tells you how far away to place a small target and then you crank the sights until the laser dot and crosshairs are in the same spot. Works great.
Even used it to sight in a Sharps in .45-70 with vernier sights. First time out it grouped 1.5” at 100 yards.
