That's been my results using the sister 50gr pellets (Blue MZ) with my two inlines
Cant imagine why you would refer to it as a sister. The only relation they have is the Alliant branding. One is made by APP and the pellets sure appear to be a IMR product with blue dye added. It would be like saying White Hots and JSG Super powder are "sisters". Its very easy to prove this just by looking at who holds the patents on both products.....Here is a hint....Its not Alliant.
If that isnt enough look at the Safety Data Sheets. The BlueMz is identical to IMR White Hots.
