I found the NEI site and I like the 835 grain cotton spool. Question is what diameter to get. .715 or .725 or .732? I want it to easy loading but still grip tight enough so as not to slip on he riflings.

They have an 1100 grain moster slug, which is a bit of an over kill I think. Although I know the gun can take it as I tried a double ball load yesterday (1100 grains of projectile) without and hint of trouble. THis was on top of 140 grains triple 7 or about 155 grain BP.

Kicked like a bear though.
