Still a little confused on the FFG and FFFG. I'm gona get some to shoot out of my Encore 209x50. I see people shooting in lines saying they shoot both.Maybe I'm confused.I only want to shoot one. I want to get the most bang for my buck since that stuff is a bit more in price. I need some advice from some of you guys that shoot loose powder on a consistant basis. I've seen the 777 loose powder containers and one had a silver ring on top and the other had a kind of gold ring, where it says sulpher free. Which should I be using 2F or 3F. Hope that helps explain what I'm asking
