I believe these used a musket cap- larger than standard percussion caps- shaped a bit like a top hat.
If they are the proper size.
Women's clothing sizes in South Africa are typically in sync with UK sizes. The corresponding US size is one size lower. So a size 10 in South Africa (or the UK) is a size 8 in the US, or a size 6 in South Africa is a size 4 in the US, etc.
Depends on the size of the dog. A small dog about the size of a golf ball. A great dane about the size of a soft ball. Other size dogs vary with the size of the dog. Medium size about the size of a baseball.
Kim Kardashian wears a size 6.
I've wonder about his shoe size myself. They look to be over size 13's!
a rifle cap.
It should be a #11 cap.
it is the measure of the width of the bore, given in millimeters or fractions of an inch. Thus you can have a .303 Enfield, or an 8mm Mauser.
Number 11 percussion caps.
The correct size of the bullet that fits the rifle.
Bigger = deeper Smaller = higher
Standard #11 cap
By handling it
The 7mm designation is a reference to the bore size, or diameter. In decimal size it means this rifle has a barrel groove diameter of .284 inch.
There is no one answer- it depends on the rifle. They are generally less powerful than a full size battle rifle cartridge. The M16 rifle uses a 5.56mm bullet, the AK47 a 7.62mm bullet, etc.
Caliber
Are you asking about caliber or the actual size of the rifle?
