I'm sure ya'll have discussed this. another post got me looking at photos of some of my guns and some of the photos are of patterns I shot a few years ago. most of the patterns shot do not match the choke measurements as to what is commonly listed on choke charts.

for instance, I have a superposed 410 skeet that at 30 yrds patterned mod/full as far as percentage of shot in the circle.

28ga super with Simmons barrels measured at .001/.001 patters IM/full.

Parker VH 20ga measures .014/.006 but patterns full/full.

Uggie 410 marked IM/mod patterns full/full.

Belgian 28ga sxs measures .010/.011 but patterns IM/IM.

Model 21 12ga measures .010/.032 patterns mod/full.


I have 2 Superposed 12ga trap guns that are full/extra full and pattern perfectly.

Is this a result of modern shells with shot cups and choke charts being out of date?
