So, I know what DAC is, but I, for one, do not know at what point along the comb the measurement is taken. Is it just behind the nose, is it where the cheek (of the seller) impacts the comb, is it at some pre-determined point between the nose and the heel?

If there is standard for this measurement I would really like to know what it is. When I review buttstock dimensions on a gun I pay close attention, because I am a shooter .......... not a collector who wants safe queens.

Thanks, SRH

I suspect it would pay to ask the seller the point where they measured it....

Just saying.

B-B = DAC
A-A = DAH
Measurement in the middle of the comb may be called "drop at face"

It's rare for you, but that is a good point. But, the other question I asked is........ is there a standard?



And, what does "in good proportion" mean, Doc?

SRH

It goes on to describe the drops, I find 1&1/2 x 2&1/2 right for "most" people. Kinda why the average guy can shoot a M12 or an 870 pretty well.

Sorry Stan. The post-1913 order form only specified DAH and LOP so the DAC was in "good proportion"



Hunter Arms standard stock with a hard rubber buttplate was 14 1/4" LOP from the front trigger, 1 5/8" DAC, 2 3/4" DAH, with a positive/down pitch of about 2 1/2" for a 30" barrel gun

Monte Carlo dimensions from Pigeon Shooting by Capt. A.W. 'Bluerock' Money, 1896. B1-B1 was called "drop at monte carlo"

Stan,
That's something I've often wondered myself.
According to Brian Bilinski at Fieldsport in Traverse City, he specifies drop at face taken midway between the nose of the comb and the heel in addition to the typical dimensions of drop at comb and at heel. My "magic" number happens to be 2".
Hope this helps.

Didn't mean to put you on the spot, Drew. But, the phrase "in good proportion" does sound more like advertising hype than detail, doesn't it? I've never seen any evidence of a standard, but that doesn't mean it doesn't exist..

I had my stock fittings measurements done by Brian Bilinski as well.

On my fitted stocks, that measurement is from where my cheek touches the comb to the plumbline of the trigger.

Stan is correct if you have a long neck or a Shortneck or you cant your head or you tilt it forward, it effects the drop at comb that the shooter experiences.

What he�s really doing is lining his eye up behind the rib by head movement.

We seldom talk about how fat the stock is where the cheek intersects the comb, because in addition to the up and down measurement, there is also a side to side measurement.

To shoot really well, the shotgun comes up to the face and you don�t have to move your head. But, if you shoot a lot of different shotguns, that ain�t gonna happen.

Back when I was concerned about it, I would just try to get the drop at comb measured along the centerline of the stock close enough, Nothing too outrageously different than what I require, and I just worked from there.

Ultimately, I can adapt to about half an inch too much, but not an inch.
There�s just too many of the old guns that interest me, that what came from the factory was way different than what I shoot well, so if I was going to enjoy them, it was either turn them into something that they weren�t, or just except that I was never going to shoot them great.
I embrace my mediocrity spread out over a bunch of guns.

I once read Yardley's book entitled "Gunfitting", but cannot remember whether or not anything in it was in reference to this.
