Barrel weight
For any given Shiloh barrel length what is the weight difference between a round barrel and a standard octagon barrel?

Re: Barrel weight
A circle inscribed inside an octagon has .9239 of the area of the octagon, so it would seem that if the barrels were the same size that the round barrel would weigh 92% of the octagon barrel.

Re: Barrel weight
Wouldn't it be the opposite since the major peaks of the octagon barrel would be the diameter of the round barrel? So the round barrel will weigh 8% more than the octagon? Or does Shiloh start with octagon materials, and cut it down to round?

Re: Barrel weight
It would indeed be pretty weird to start with machining a barrel octagon to make it round afterwards... So the round barrel you start off with for octagoning should always be heavier than the finished product. Of course, you could specify a smaller diameter round barrel, but then you're comparing apples to oranges.

Re: Barrel weight
The round barrel on my 1877 feels bigger than the octagon on my 1874 , I will measure it to know for sure.

Smoke? Have you considered the possibility that you have been spending too much time afield searching for road killed 'Possums?

Re: Barrel weight
On half octagon barrels, the round portion is usually almost even with the flats of the octagon portion. So it appears they make the octagon first, and then turn the round so the peaks of the octagon are above the round.

Re: Barrel weight
Double D, Tom Klinger down here in Florida went out to Texas and walked away with all the winnings. I thought he would at least got a pair of cowboy boots, but no. I have promised him a pair of possum hide boots, so I'm collecting hides for that. They are sharp boots, I leave the tail on the hide, it drags the ground behind the heal of the boot. Sorry OP, didn't mean to hijack your thread.

Re: Barrel weight
Well, if they are for Tom, better reconsider. The nine banded Armadillo (plentiful in the Sunshine State) provides a far mor durable exoskeleton for native Floridian footwear.... You shouldn't have to ask me how I know.
BTW, Mexico crafts women's purses from the entire Armadillo exoskeleton. Tough doesn't quite describe their durability.

Re: Barrel weight
Submerge one of each in water and derive their relative volume/weight. I think calculus is involved if one wants to work with all of the internal/external dimensions.

Re: Barrel weight
Barrel manufacturers list barrels as blanks or profiled.
I have seen and received barrels from manufacturers described as blanks and all have been round, most in the rough.
If the barrel is listed by the manufacturer as profiled, that barrel arrives as octagon, (which means 8 sided), whether submerged in water or not.
By deductive reasoning, (reasoning being the operative word here), the profiled barrel that started out round would be lighter than it was as an original round blank because metal, (weight), was removed to convert it from round to profiled.
And no, I was not a rocket scientist in this or an earlier life as far as I know.
