I have asked this question before, and never really gotten an answer that made sense to me. I know a number of very knowlegable people who claim that Pitch is for comfort only, and has no bearing on point of impact...Michael Yardley's book seems to suggest this, and that is the only treatise on the subject I own. One person I know and respect says he just cuts his stocks off at 90 degrees to the comb.

However, I keep hearing people say that Pitch is an important factor in fit. The naysayers always drown them out, but I would like to hear from someone an explanation of how pitch is correctly determined, how it affects fit, and whether and how it affects the point of impact. I'm really only interested at this point in those who believe pitch IS an important element of fit beyond mere comfort, so if you don't think it is please bite your tongue until others have had a chance to weigh in. Anyone out there want to take a stab at this?
Thanks

I think pitch comes into play when you have a larger chest,or are a women.I am a larger guy and have a bigger chest.When my stocks are cut at 90 degree's i shoot higher.That is because the heal of the butt is resting more on my chest that the top of the butt.This makes the top of the butt move in a little with the recoil.making me shoot a little higher.I like to cut my stocks at about a 7 degree angle to the rib line.(the line straight across the top of the gun that is level with the rib,from end of barrel to the butt.)This lets the butt rest evenly in my shoulder.I then dont have the problem of shooting high.

YES, The PITCH of the butt stock is very very important if you want to hit flying targets with a shotgun. It is just as important as any other dimension. The shotgun has got to stay on your shoulder and in the pocket so you can keep your head, eye, steady on the stock as you swing/move the gun. Jent

Hi
For the most part I think if the pitch is not exagerated it does not affect you very much, but if the pitch is severe it can really affect you. I have a 16 ga o/u francotte that had severe pitch and when patterning the gun it caused the gun to shoot very high for me. I trimmed the stock to be more neutral pitch (about .75")and it lowered the poi many inches I think about 8"-10"(at 16 yds). That is my experience.

"Most people are accommodated by 5 to 7 degrees positive pitch." --"Col." Glenn Baker

As with so many normative distributions, the majority can pick em off the rack and shoot em altho some may have the means to have someone else agonize over why or why not. Keeps you from scratching up the drywall, fumed oak wainscotting, or whatever, with the front bead.

Thanks Pawnbroker and Jeff, that's what I was looking for--I'm starting from an assumption that it does have an effect and am wondering exactly how to quantify that effect.

Am I underdstand you a gun that is long in the toe/short on the comb (positive pitch?) will cause you to mount a gun a tad "higher" in order that you get full contact with the butt, and therefore will shoot a bit higher? And that conversely a gun that is longer in the comb/shorter in the toe will cause a slightly "lower" mount in order to get full contact with the butt, and cause you to shoot a bit lower? This would explain why a trap gun might have a longer toe...?

If so, how does one differentiate between when you need a pitch change and when you would be better off with a change in comb height? I suppose you could achieve the same result either way? However, how does a fitter arrive at an "ideal" prescribed set of measurements for a bespoke gun, i.e. how does one prescribe one over the other?

Thanks

Edit: yes, I know that I have better things to concern myself over--I'm just trying to understand this 99% as an academic excercise.

Hugh Lomas (Hugh G. Lomas Gunmakers) once gave me a really good explanation for pitch. I don't remember the details, but if you send him an e-mail, or dial him up he will put it all into perspective for you. You can google him for contact info.

The gun he restored and set up for me fits like a glove.

(David Furman) Which Yardley book are you speaking of? My understanding of his writing's is that pitch has less effect on tightly held pre mounted trap guns where they use two beads set in a figure eight pattern. But, I understand less every day! As far as gun fit that covers all types of shooting, I think he is the most knowledgeable I have ever read. I think all your questions are answered in his books. He is one of the few who fit a gun and have you hitting without demanding you use his style of shooting. On the shotgun stocks I've had made pitch has had much more effect than comfort.

Too little or too much pitch causes an uneven distribution of the linear force of recoil. If the pitch is off you will experience felt recoil more at the top or bottom of the pad than if the surface of the pad was more evenly distributed on the shoulder. Also, with improper pitch, the recoil can cause a pivot effect on your shoulder when the shell goes off so that the stock rises into the cheek increasing your felt recoil on your face and putting your gun out of position for a quick second shot.

Lastly, inproper pitch promotes improper gunmount, which will affect where your shot pattern goes.

Proper pitch is achieved when you get maximum contact between your shoulder pocket and the buttplate or pad, for best distribution of recoil. If your cheek is properly on the comb, pitch will not affect your impact point(high or low). 100 years ago, before people discovered the cheek should be placed on the comb, pitch mattered much more. If it was important now, people using those "banana" pads would shoot their toes off. JMO and JME
