Hodgdon Clays powder Rem. 209P WAA12SL 1oz shot 6,500psi 1,125fps I have the components to make these, and it is my understanding, if not incorrect, that Fox said their 2&5/8 chambers were intended for the 2&3/4 inch shell. I'm only going to use the guns on rare occasions anyway, as there is very little to hunt around here with a shogun, and should I do any extensive shooting, I will choose another shotgun. Thanks for the advice.
