WHAT DOES BLACKHORN 209 POWDER IN STOCK MEAN?

Blackhorn powder is arms down the cleanest and most effective shooting powder that I've ever employed! I'm taking pictures 80grn by quantity with hornady xtp 240s and they are tack drivers at 100yds! I have not experienced a misfire making use of Blackhorn 209 and Winchester W209 primers!Missing your password? Make sure you enter your username or e
