What size shell in legnth are you asking about?
No one answer. That depends on the load and the powder used. Please understand that as used in that sentence, grain refers to a unit of weight, and not the individual grains of powder. Typical charge weights can vary from 17-35 grains.
It depends on the gauge and length of the shell, but common 12 gauge shells have between 25-45 grains of powder in.That range is determined by the wt. of shot/slug and the speed you want to shoot.In other word do you want to shoot trap at 1100 with 7/8Oz. shot or a goose upward of 1300fps with 1 1/4 Oz of shot.
With ammunition, the term GRAIN is a measure of weight- there are 7000 grains to a US pound. It does not refer to the number of individual flakes of powder (grains). Load data will vary depending on the weight of shot to be fired, and how hard you want that to shoot- and it also varies depending on which of several powders you use. For example, a 1 oz shot load might use from 20-25 grains of powder X, 22-27 grains of powder Y- and a 1 1/8th oz shot load might use 18-14 grains of X, etc.
That is a shell with a larger powder capacity based on a previously existing shell. Example: Modern .22s come in short, long rifle, and magnum. The magnum is a bit longer than the long rifle and contains a few grains more powder for higher velocity.
Follow the instruction in the owner's manual. If you don't have one, contact Knight. Good advice, If you don't know how to do it get instruction from a local club member or black powder shooter. Your local gun shop may be able to put you in touch with someone. The loading is just like loading a shotgun shell. I use 60 grains of 2F powder, then an over powder wad or a shot cup depending on what I am hunting, then 1oz of ___ (fill in the blank depending on what you are hunting) shot, followed by an over shot card. Same as a shot shell but the barrel is the hull.
i loaded 1 shell with the 110 bushing that showed on my scale as around 20 grains. my scale wont read down to .9
The 20-gauge shell will fall into the barrel and lodge. When a properly fitting 12-gauge shell is chambered and fired, it will blow up the barrel and you will have a very bad day.
NO!!! A 12 gauge shotgun takes only 12 gauge shells. A 20 gauge shell would fall into the barrel and get stuck about half way to the muzzle. You would be in for a nasty surprise when you put a 12 gauge shell behind it and pulled the trigger!!!
Because of the different burning rate of the various types of gun powder used in loading shotshells there is very, very little correlation between the two terms. Shot shell manufactures should have dropped the term 90 years ago.
There is no propellant in the shell, the projectile is powered entirely by the primer. You can take one apart and see for yourself.
It depends on the shell you fire.
