I tried it last year. I have only used about a 1/3 of the can. I am new to muzzle loading as of last year. What drew me in was the no need to swab between shots. In my Optima Elite however, I was only able to load about two consecutive with the 200gr Shockwaves before I couldn't load another. I did come up with a load at 90gr that shot a 1.5" group at 100yds. I just started spit a dry patching after everyshot though. The grains of the powder are not consistent at all. I just tried BH209 this past weekend and don't think I'll go to anything else. Now I have about 2/3 a can of Shockeys to either give away or shoot up.
