I don't believe i ever said you could use the powerstem with pellets Triple Se7en

This thread has expanded on it's original topic Newman. Read the post again by big country - just prior to mine.
Yea, Triple, thats one down fall I found in my report below. After 15 rounds there was some crud but not near as much as I imagined. But knight said don't worry about. But I beg to differ. I don't think any danger, but now your charge has moved the sabot up a little at least, and would change the way it was fired and accuracy. One thing I was surprised, is how much cleaner the powerstem cause it to burn. I mean you shouldn't have to swap every shot even with tight sabots like barnes.
I had good luck so must not be a huge issue.
Have you ever considered the expensive Black Mag-3 for that stem?
The powder is FFF-composition - strength is very good, recoil is lessened & fouling is very minimal according to range reports here.
