In response to Sabotloader; I agree pretty much with all that you have posted. I am not sure what rifle you are using but the Omega is definately not a prime contender for Tripple Seven (at least mine is not). I have a stainless .50 which has been smoothed a little with JB bore paste (about 200 passes) and still will not allow a second shot with 777 no matter what primer is used. I can get multiple shots (at least four or five) using BM3 and Pinacle looks like it will allow multiple shots also. American Pioneer would let me load two or three in a row before the fouling would stop a sabot. Powerbelts can be loaded a couple times more before problems start. I have obtained all three face configuration breechplugs that were made for the Encore/Omega and some are better for fouling with some powders. The flat faced one seems to be the worst for 777 crud ring. The latest with a recess but a flat ring around the recess seems to be better. I have mostly shot loose 777 so I cannot comment on the pellets. I have had extremely good luck for accuracy with 300gr. bullets in Harvester sabots with both Pyrodex and Black Mag'3 (between 80 and 100 grains of powder). I also had very good accuracy at 100 yards or less with 80gr. Pyrodex and 295gr. Powerbelts. At 80 yards they cloverleaf from my rifle off the bench with a scope. I plan to stay with the .25 conversion which works great for me and is easy to do as I have a lot of once fired .25 brass that I scrounged from a shooting area. I even have the reloading dies for them (now that is one you don't see reloaded a lot).
