Has anyone used these bullets. They are a small company. They have a couple different thicknesses of copper jacket .025 and .035 suppose to control expansion on different size of game. The bullets come in 7 different diameters in various weights. I have some 275 grain .430 and .475 Flat Point bullets ordered. They also come in Hollow Point.
