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
Drew's diagrams haven't changed much over the years. DAC is usually measured at the start of the comb even today by most.
Not a huge fan of Don Currie but
#2 is standard for DAC measurement from all the books I have on it.
Currie's diagram does bring up a good point, that there are a lot of other measurements to gun fit. #3 is Drop at Face and Dave Erickson gave a great example of that. He shot that custom ordered Iside well before shaping and expect he will now be even a stronger force to be contended with. Oh just freaking great
Comb thickness was also mentioned and has a huge impact IMO. 870's and model 12's were mentioned but the Ithaca 37 field has no pitch, and no cast. And a very thin comb. I shoot them extremely well.
Surprised that the parallel comb that Drew also mentioned hasn't taken off more than it has over the years. Didn't realize it has been around that long. On my target shotguns I normally set them up to be as parallel as possible. With a 4 way adjustable comb and using offset. Even on my 32" Dickinson Sporting gun.
Still a work in progress and sometimes regret selling my 682 Gold target gun. Sometimes..
I can pick up my 20 ga. Winchester 23 and usually hammer targets with factory dimensions which are different than most of my other target and hunting guns. As long as I don't think and use swing through.
Metrics can be measured with consistency. Measure at the start of the comb, most do. But there are a lot of other measurements involved IME. It is complicated...
Well not really, see the bird shoot the bird. But it sure helps if the gun shoots where you are expecting it to and are used to.
