I have shot both Pyrodex and Triple Seven both in pellet form and loose powder form. I finally got a jug of APP loose FFF powder andI honestly don't thinkI will ever switch back toany other kind of powder. It is the best thingI have ever shot out of a front loader and the ease of cleaning goes umatched by any other type of powder . My T/C Omega loves 90-100 grains of FFF APP behind a 348 grain powerbelt.
