I have been buffering loads out an Encore muzzleloader for years now, currently I am loading #7 Tungsten Super Shot (which is very close to the density of the Federal heavyweight shot). However, I have loaded original Hevi-Shot and also Turkey Trauma 13 with great results. I am loading 1 3/4 ounce of shot in a Ballistic Product's TPS wad trimmed to proper length to accommodate shot, over 105 grains of Triple 7. I use one scoopful (2.5 cc) of Mix #47 buffer to each load. The process of loading this is very extensive though and takes a long time to do it properly, and I have also made a long paper funnel to be able to get powder and buffer, both of which love to adhere to the choke threads past them without any mess at all. I load in the order as follows: Powder, fiber wad, 2 felt cushion wads, now seat TPS wad with trimmed cushion wads to take up some space in the bottom of the TPS wad, now pre-measured amount of shot with a scoop of buffer on TOP of the shot in a 35mm film container, pour this down the paper funnel and into the wad you have seated earlier, tap the lower barrel excessively to distribute the buffer, seat another fiber wad and I top it all off with one of the black Styrofoam cards that used to come in the bag of Knight wads. Re-install choke (Indian Creek has performed the best out of this muzzleloader for me). Next step... go smoke a big long beard! The patterns this combo generates are truly awesome. My buddies say I am nuts and it it way to much effort for one shot, but I enjoy doing it and love to try new things and a muzzleloading shotgun is a perfect way to experiment. I have tried many different loads and techniques of loading and this has been far and away the best. Best of Luck.
