I bought several boxes in each of several bullet weights.
None of the current reports contain any physical data: no velocity figures, no bullet weight.
That's the same bullet weight as the 4-bore, but at twice the velocity.
Increased powder loads in combination with increased bullet weight may create dangerous pressure conditions.
He put several boxes aside in case he didn't find the bullet weight he wanted.
He would have to compensate for the slightly heavier bullet weight when he took the shot.
Ammunition makers often offer several bullet weights and types for a given cartridge.
The power of a given cartridge is measured by both bullet weight and velocity.
This led to the .22 Long, same bullet weight as the short, but with a longer case and 5 grains (320 mg) of black powder.
This works out to be about 22% more powder for equal velocity with the same bullet weight.
