WADR, that is a very LARGE Priming Horn. More like a day horn, IMHO. you might want to cut that thing down by 1/3. Priming rarely requires more than 6-10 grains of powder on the largest flash pan. You certainly won't use that much powder even squirrel hunting( with large daily bag limits).
One of the reasons that many members here are advocating using FFFg powder for both their main charge, and for priming is that they can get by with a small horn- a day horn, and use only one horn for both functions.
If you make a horn that will hold 500 grains of powder, that would give you 50 shots, if you are only using it to prime. If you hunt small game with a .36 caliber, or .32 caliber rifle, the powder charges are rarely more than 30 grains. 20-30 grains of FFFg is the usual range of powder charges for these two calibers. That 500 grain horn would still give you more than 15 shots!
A Quarter pound of powder would be 1750 grains. The horn you are holding will hold more than 1/2 a pound of powder. The smaller " day horn" will give you enough powder for most hunting situations you are likely to experience, and will save you the weight of carrying around all that extra, unused powder.
If you want to really make JUST a priming horn, you might consider flattening the horn so that it will fit in a pocket, or your hunting bag easier. You certainly have talent using horns to make calls, and flat horns are few and far between enough to generate interest from MLers. Small, flat horns that can fit in a shirt pocket always draw comments from shooters, wherever I go. " Can I see that horn?" is the most common reaction I hear. :thumbsup:
