If you are looking to cut the tails, instead of shoot them with a mandrel, look at the angling ai tube molds, they have 2 different 2.75” versions, slender and double dipper. I have the double dipper and it makes a great tube, and super easy to shoot. Cutting the tails is a bit of a pain, but I like then end result better than the injected tails, all personal preference though.
