Barrel Taper Profiles

[Austin W Hogan]

Larry Frey, Dave Suponski, Dean Romig, Mark Conrad, and I are working on a Parker Pages article on Parker barrel taper. We need some measurements of several guns of interest to complete this article;
One frame twelve gauge of less than 7 1/4 pound total gun weight.

Twenty gauge guns, but especially twenties on 1 or 1 1/2 frames

Twenty eight gauge guns on the 0 frame.

The data needed are gun grade, serial, frame size, barrel length, initial barrel weight (as stamped), current barrel weight, gauge and total gun weight.
and
The breadth (width)of the barrel set, and the outside diameter of one barrel at the listed distances fromthe breech end.

The weight can be taken with a household scale of ounce accuracy.

The barrel measurements can be made by laying the barrel on a yard stick and measuring the distance across the barrels at each point. Then lay the yardstick on the rib (or hold it with a rubber band or a spring clamp) and measure the outside diameter of one barrel from the front of the flat to the muzzle at the same points. The measurements are most easily made with a caliper.

We have learned some interesting things about barrel taper, muzzle dimensions, and nominal thickness of larger guns so far. A few more lighter gun measurements will make an interesting study.

Thanks, Austin
