Well I am new to this also and had a few problems with mine.The powder hopper wouldnt fit down in like it was suppose to.So instead of sending it back I tapered it with a dremel.I also poured powder in and watched it spill on my bench Glad I aint alone on this.I have a lot to learn about this but I got a good teacher.So after waiting 30 yrs to do this I took the plunge.The info I got here I will keep in mind thanx.
