What everyone else said. I'll add that I am starting to believe it may be the wrong powder or grains of powder. I am looking for evidence that burnt propellant ignites outside the barrel and that could cause a bullet deflection. For certain rigs I have with 100% burnt propellant I don't get fliers very often when I slow down and do my part. Just a theory right now but it's working for me. I use GRT.
