Recreating The American Longrifle IMO is a very good book . Not as fancy as "The Gunsmith of Grenville County." But its what most all of us older smiths and builders started out with . You have to look at it as a book . The book has an order . You build in that order . If you try and take the chapters out of context of that order , then your going to get confused . Not to mention things become complicated . Once you understand the basics and how the placement of each component effects the placement of another , then you can start using the book as a reference
Your transitions should start up at the center of the tang screw .
Drop and cast is not an case of ; it is what it is .
These are things that are specific to a given person or a given style of shooting .
Today production manufactures build for an average shooter ..
But by trying to work this out now , you are jumping ahead and thus your becoming confused .
You need to start with understanding the why of things .
I would like to follow the lines of the LeMann but man... that butt... it has to hurt,
That would be true if one were to shoot that style of rifle from high on the shoulder . But when we understand that the rifle was designed to shoot from lower on the shoulder to top of the arm , we then see that it wont hurt . We also then see that the very deep cresant shapes , must be shoot from the arm , not the shoulder
See , once we start to understand the shapes We can even then go to the extreme and understand why the evolution of some of the very deep butt plates on some target rifles
. See by understand that many of these were meant to be shot from under the armpit . IE a laid back , backwards prone position , not off the shoulder .
As such this shooting style effect the drop and the cast . Today people are built differently then they were 150 years ago . We are taller , heavier and in some cases our necks and arms are longer . that’s where the drop comes in .
Let me see if I can explain this to you . When you shoot a rifle that’s been designed to be shot off hand , for a specific person , that rifle , when brought to the shoulder , should yield the persons eye to instantly be inline with the sight . The less movement , the shooter has to do to make that alignment the better ,IE leaning forward or tilting the head to the side . Thus if one has a short neck , their drop will be less then someone with a tall neck . Same holds true for cast in that a person with wide shoulders often needs more cast then a person with narrow shoulders . Now add in a gun designed to be shot from the arm and not the shoulder and you can see that such a gun would need even more cast so as to reduce the shooters need to hunt for the sights .
Next consideration come style of shooting . Is the gun designed to be shot with a forward facing stance like a shot gun or a more side type of stance with the shoulder in the same direction as the target . IE the gun runs more across the chest the away from it .
Once you understand these things you then can decide of you drop and cast .
You also will then be able to look at a given rifle and understand the type of person it was made for and how it was to be shot . As well as why the rifle has the lines it does
I like the lines of the one ridjrunr posted in reply to one of my questions... but this is going to be a flint... I think...(I have only changed my mind four times to date.)
there is this misconception that all half stocks must be percussion guns . this isnt true .
the Hawken Bros did not invent the half stock rifle . in fact the lines of their guns wasn’t even innovative. Even if we hold the conclusion that they did do something special , they basically only re invented the wheel as the plains type rifles very much resemble the early European half stock sporting rifles .
Here are some other ½ stock rifles for you to look at . As you look at these , try and look past the gun and look at the details of the gun . Notice the differences in the barrels
Some are round , others swamped , others tapered . Notice the differences in the drop . Look at the butt plate designs and see if you can understand how the rifle was ment to be shot .
I am also including a photo of a gun made by Gustuvus Erichson in Texas in or around 1838 .
Notice the gun is a ½ stocked flintlock . It also carries a longer swamped barrel .
Notice the drop of the stock . See that the butt plate isn’t of a design that’s shot off the shoulder ?.
This tells me that the person it was built for most likely had a tall neck and did a lot of off hand shooting .
As such , even for it length , for such a person , the rifle would have been quick in the draw
Gustavus Erichson was a gun maker, gunsmith, and gun dealer in Houston from 1838 until 1872. Two of his sons, Otto and Alexander, continued the business until the 1890s.
An amazing rifle has just been discovered hidden away in the vault at the Sam Houston Memorial Museum in Huntsville, Texas. An original flintlock rifle that appears to have been stocked in Houston as early as 1840 and stamped G. ERICHSON HOUSTON. TEXAS. on the lock and the barrel. Mounted in iron with a pewter nosecap, stocked in walnut. This large rifle measures 61 inches overall and has a 43 5/8", .51 caliber, swamped barrel. The rifle is in fine shape and, at this time, is the only known Texas marked flintlock sporting rifle.
