Slightly Confused?

[Halftail]

I have been browsing Jim Chambers site and catalog.I am kind of interested in the Pennsylvania Fowler. I see that the LOP is 13 and 7/8ths.Drop at heel...3and1/4 and the Drop at comb is 2 inches.My question,what does Drop at Heel or at Comb mean?How would I determine if the LOP would fit me?I have an Early Yorke from Chambers and it's fine to shoot.The LOP on that one is the same.
I'm interested in a kit but I'm greener than grass when it comes to building but I figure I could tackle it ,maybe this winter.
Here is the link to the two I'm looking at... Chambers Smoothbores

It will fit you. Imagine a line extended backwards from the sight line. Now drop a perpendicular to the nose of the comb. That is drop at comb. Now drop a line perpendicular from that sight line down to the heel. That is drop at heel. These dimensions on those Chambers guns are about like a modern pump shotgun, so can work for about 80% of male shooters without any contortions.

Drop at the heel is how far the heel is below the line of sight down the flat top of the barrel;

Drop at the comb is how far the comb is below the line of sight down the flat top of the barrel.

Stand the long gun vertically against a wall with the barrel pressed flat against the wall.

Then measure from the wall out to the heel of the butt stock...that's "drop at the heel".

Then measure the distance to the comb for "drop at the comb"

Once you know the LOP, DAH, and DAC of a gun that fits you well, the majority of guns with those same dimensions will also fit well

Gees,
Thanks guys! :applause: I guess I'm not too thick headed to learn something today! :v I'm going to check out the measurments of the Yorke and compare with the Smoothy then decide.

Average shotgun drops are 1 1/2 at comb and 2 1/2 at heel. That allows "most" guys to adjust the gun enough to fit themselves to the gun. This is not the ideal especially if shooting shot but if aiming the gun you should be OK.
The York has close to the same dimensions as the PA so you should be fine. I had the PA and it was nice and slim but way too much drop for me to shoot it good.

A little cast-off can be nice too...

 

[torn moc]

Ok RUSSTFRIZZEN.....please explain "Cast off"
thats a new one to me...and I am sure others would like to know also......the inquiring mind syndrome ya know?

By Bob Spencer.....

The terms 'cast-off' and 'cast-on' are also used to describe stock configuration. Simply put, they refer to the deviation of the butt away from the center line of the gun. A gun with no cast is straight. A line down the center of the barrel will continue straight down the center of the butt stock, as viewed from above. With cast-off, the center of the butt is moved in the direction of the shoulder of the shooter. The opposite is true of cast-on, the butt deviating toward the center of the shooter's chest. The diagram at left shows cast-off in a right handed gun, by the amount between the arrows. Neither cast-off or cast-on are commonly built into guns, these days, and cast-on has always been fairly rare. The purpose of both is simply to make it easier to align the eye with the sights. Just as the height of the comb helps align the eye with the sights in a vertical direction, up and down, cast can make it easier to line the eye up in a side to side direction. A knowledgeable stock builder can use cast to cure alignment problems for people with particularly wide or narrow faces, for example. This curve in the stock can be accomplished either by steam-bending the straight stock or by carving the curve in as the gun is made, which is better.

Cast-off and cast-on are used far less frequently than most other elements to affect stock fit. The British have always made a big point of the usefulness of cast, especially in shotguns, which must come to the shoulder quickly and without hesitation, lined up right the first time. Few modern American guns have ever had it, and most of the available black powder guns in today's market are made without cast, as far as I am aware.

The average shooter will find a gun with 1/8 to 3/8 inch of cast-off to be a comfortable one to shoot.

This might help.

The Smoothy I had built has a 3/16 cast off.

It is good Halftail is only partially comfused, otherwise he'd'a probably slipped in antidisestablishmentarianism. :shake:

 

[Russ T Frizzen]

I find 3/16" to 1/4" of cast off to be about right. It is unlikely that a production gun will have any cast off, but most handmade guns I've seen have some. A proper balance of pull, drop and cast off makes for a very sweet gun indeed.
I was able to put a little bit of cast off into my Seneca when I refinished it, and it really changed the way it comes to shoulder.

Thanks Slammy,
Now I'm totally confused.

No need to be confused, it's just the longest, almost never used word in the English language :grin:
