How do you measure chokes?

[Night-king]

What's the most reliable way to measure shotgun chokes? I've seen folks use calipers, drop-in gauges, even just patterning on paper. For those who've done it a while, which method gives the most consistent results?

Patterning on paper at 40 yards is best for real results. Shoot a few sheets and measure pellet spread. Calipers work for quick checks but miss bore wear.

I get that patterning on paper is reliable, but my concern is consistency...conditions like wind, distance, and ammo brand can all change results. How do you make sure testing stays accurate?

Yeah, that makes sense. I've been leaning toward paper patterning myself, seems like the only way to see how it actually performs instead of just relying

Good point, man. I usually shoot a few patterns with the same load on calm days, then average results. It keeps it fair and helps spot real choke performance, not weather quirks

If they are not marked all the measurement devices mentioned by the op work. Everything depends on intended use. Upland game , Waterfowl, clays, or defensive patterning on paper makes sense. As with anything the ability to hit ones desired target takes practice, practice, and more practice.

Use gauges or calipers to check what you've got. Once you know your stuff, go ahead and figure out the patterns for the ones you’re planning to hunt or shoot with.
