Proper measurement of stock dimensions

[Double Trouble]

Is there a specific "standard method" to measure stock dimensions ? Specifically, drop at comb (DAC) and drop at heel (DAH).

Here's how I measure them: Using a straight metal ruler, I lay it NEXT to the front bead, along the top of the rib. Then I measure the perpendicular distance from the ruler to the front-most part of the comb (for DAC), and then do the same at the "spur" on the Parker buttplate (for DAH).

Is this "right?" My letter claims my Parker has a DAH of 2 7/8", but in order to get that measurement, I need to measure it approx. 3/4 of an inch forward from the buttplate spur.

What is the proper/standard way ?????

Thanks guys !

That's the way I've always done it. LOP I use the front trigger to the middle of the butt. Interested to see what others say.

Thanks. I've heard that length of pull should be on a line parallel to the line of sight (the ruler). IE: Not the direct distance from front trigger to the middle of the buttplate. As a result, the "proper" way will be a tiny bit shorter than the "direct line" measurement. (But either way probably yields a VERY similar result...)

Others ?

length of pull is from the front trigger to the center of the buttplate/pad

your DAC and DAH are the best way without a specialty guage

IMHO the drop at your cheek point is really the one that matters - that is where your rear sight aka eye goes

I don't have a measuring gauge so I simply lay the gun (double barrel) upside down on a flat table. I measure from the comb of the stock to the table and then the end of the butt stock to the table. For length of pull I have never seen anything but measuring from the front trigger to the middle of the butt plate. I agree with Rick that the one that matters is the drop at comb. As your eye is the rear sight that gives the most important impact on your ability to hit what you aim at.

Where can I down load That copy of the Purdey Stock measurement form to print for a refference sheet?
Thanks

Hello Gerald, Let me know, if you can't come up with the measurement chart, I am pretty sure one of my packed away Purdey Catalogs will have a copy/info that I can scan for you. Tom

Upside down on a granite island top, with the front bead off the edge, always does the job for me. For a surprize, try lining up three or more guns at the same time and sight down the long axis from the butt ends. Small amounts of twist and cast become apparent that aren't readily noticeable looking at one gun only. Look across the guns at the buttplate and you can see the differences in pitch. Then you realize why some guns just seem to fit better than others. Best.
