I start this discussion with intent to put the subject up for commentary and input by all, as an vehicle for education and sharing of information. Let me state categorically, I am not an expert on this subject. I stepped into the world of picket and slug rifles quite accidentally about 4-5 years ago and the biggest point learned to date is that I don't know the half of it. It is, in today's world, a small niche in the shooting world, albeit a very interesting niche.
The history of BP competition shooting is rife with respected names in the history of shooting sports in the US. Billinghurst, Mann, Warner, Perry, Pope to name a very few. What I want to discuss is that period in between the early days of social shooting with roundball guns and the advent of smokeless propellant and jacketed bullets, not because I have an agenda to push, but because it is a topic that can be discussed to the end of time otherwise.
Chunk guns are neat. Schuetzen rifles are perhaps the finest art crafted in the shooting world. They are for another thread and I'd urge anyone disposed to those disciplines to start discussion on them at their leisure. Mostly I'd like to keep this focused, in very general terms, to the era of the National Rifle Club, that being generally the post Civil War time frame until about 1900. I know for a fact that some of you here will know more about this than me and I welcome corrections and additions equally.
PICKET RIFLES
Somewhere around the first half of the 19th Century the use of percussion caps became common, as did the act of converting flint lock arms to cap locks. As far as I can determine the use of conical bullets for competition began somewhere in the 1840s. The advantage of conical bullet forms over round balls is well known, but many do not know what a picket bullet is. They take three forms: Sugarloaf, Flat base and Lewis style. They are illustrated below.
Sugarloaf style:
Flat base picket (one each end) and Lewis belted picket (center):
There are several points of interest here. The picket rifles were transitional in nature, providing improvement to downrange ballistic performance as well and a new slope on the learning curve. The early sugarloaf bullets were mostly cloth patched and as is attendant to all such bullets had little bearing surface. On one part it was difficult to seat the sugarloaf picket bullets squarely and they are well known to suffer from flyers. The flat base designs did better but still suffered from errant flight on occasion. The advantage of the design was found in the short length, usually less than two calibers, which did not require a fast twist to stabilize them. In my limited experience with picket rifles twist rates can vary wildly, running from the teens to 48".
Furthermore, the picket bullet was, in my opinion, a fertile catalyst for experimentation. Cloth patches gave way to paper and as indicated in the photos above, great variation in form. While rifles intended for round balls trended to deeper groove depth, this was not always advantageous to shooting picket bullets. Thus the belted or double belted Lewis design and other contrivances flourished as well. In short, the rifles were able to shoot both round ball and picket forms, providing a lot of latitude in application.
One should not confuse the nature of the bullet as defining the gun. As mentioned earlier, picket bullets are short, and as a result, fairly light for caliber. The pictured bullets on the notepad however range from .45 to .56 caliber and about 300-550 grains. The guns used for pure match competition were sometimes massive, and other times used in different applications, such as competition and shooting afield. Rules change over time and frankly I do not know what requirement the NRC had for picket class rifles, if any, but in today's competition circles the rule is "less than two calibers length." That means a round ball gun can qualify for a picket match, but that a more common slug rifle will not.
Examples of such hardware is found below with brief explanation where possible.
P.A. Reinhard 1876 .38 caliber bore, 33" twist, 7 grooves, .018" groove depth, 9# w/lollipop sight and hooded wire and bead front sight. Muzzle is turned for bullet starter tools for the gun are lost. Barrel is cast steel, bore is good with a minor pit in the chamber ahead of the breech plug.
A transitional D Hilliard .50 caliber, 16#, 16X scope, 16" twist. Bullet weighs 360 grains. The twist rate allows for heavier bullets if one has sufficient determination to deal with recoil.
In the first picture there is found a false muzzle on the barrel, 2 hammer dies, bullet mould and bullet, foot rest, strip cutter and bullet starter w/monkey fist. Most if not all of these accoutrements were common to competition rifles from this era.

FM installed. The monkey fist is the brass disc with the hole in the middle. It is used to assist in patch strip alignment and/or controlling the strips during windy conditions. The patch strips are placed on the FM and the fist is laid atop. The bullet is then placed in the hole and lightly finger seated. With the fist removed the bullet starter is put in place to seat the bullet about 5-6" into the barrel. In many cases the old guns had choked barrels, meaning the bore was lapped to provide for a reduction in bore diameter at the muzzle of a very few thousandths of an inch (.001-.002"). Depending on bullet/patch/bore dimensions, some will swab the first 6" or so of bore with oil prior to seating a bullet to avoid tearing strip patches.

Hammer dies are used to swage a cast bullet into final form for shooting. The name implies it and in fact a heavy hammer is used to drive the cast bullet into the swage die by striking the ram...squarely. These dies usually have an ejector pin, in this case concealed by the base of the die on the left.
