I am interested in loading my 45-70 with a 405 grain cast bullet for muzzel velocity of around 1200 ft. per second.
I have some data using about 23 grains of 4759 with good effect. The issue is that the case is oly about half full. I wanted to add a 1/8 inch cork waffer or wad between the powder charge and the back of the cast lead bullet. I have heard that some say this air space and a thin waffer or wad might serve as a secondary projectile and cause dammage to the barrel. I would like to see some data on this effect.
Was it seen when using a modern rifle such as the 1895 CB
Marlin? What typ of powder was used? How much air space was there?
Any evidence or sharing of ideas would be appreciated.
