Nice job.
I take it this keeps it stable (heavy) what distance do you test and what is the grid or image you use?

Very heavy all steel
100 yards tall target for % of tracking

That's a great idea. Removes shooting error too. I like it.

You can also use a 72" carpenter rule hung plumb on a wall as well.
for the folks new to this use a tape to measure a 100 yards versus a laser. And as seen in this thread heavy is good it is amazing to see that scope can easily be moved a hair when cranking on the turrets.
we have done this for years while calibrating scopes

Ya, it's handy to settle an optic in it's rings and get it all dialed in off rifle, I used to have a fixed mount in my shop and a taped out 100 yards with a gridded tall target, just made life simpler after the build!!
Nicely done. Action pics please..... TargetsUSA made a really slick looking fixture similar to yours....shaped base, powder coated, engraved logo, etc.....$400 for riser and base combo. Bet you didn't spend anywhere that much. Tried for two years to buy the TaretsUSA unit to no avail. Going to build one similar to yours....different shape plate, riser bolted from bottom for easy disassembly for storage, drilled/tapped leveling bolt holes, powder coat, maybe engraved on my son's laser thingy.

Brian Litz has an article and a video.
I spent 120.00
Range in yards x moa diled x.01047 = expected poi
Divided by inches of actual poi
# track percentages
Like this scope
100.388 yards x 24.5 moa x .01047= epoi 25.751 / actual inches 26.0625 = .988 percent
You put this information in the ballistic app under sight scales vertical so the app correct for the error
