I was playing the other day how to keep bullet power and primer together. It struck me! I taped two of Lane's tubes together caps facing opposite of each other. I put powder in one and than put a 209 than a bullet on top. They will hold a 50 cal bullet or sabot bullet just perfect. Just remember to put the bullet point down or the sabot will slip off and stay in the tube. I put 5 in a small fanny pack with my short starter ready for a short walk in the woods.
