Going to buy a TOW Tulle Kit soon. I have always primed my Virginia from my horn with 3f. It has a 1/16 hole and lets off very fast. With this 20 ga. I will more than likely load with 2f. If I choose to prime from my horn with 2f, what would be the best size for optimum ignition.Is it something I should work up for this particular smoothbore? Any thoughts appreciated.
