Antique/Vintage Dupont Improved Military Rifle Powder 4350 Cannister

This was the first propellant I ever used when I first started reloading and tailor customizing my own ammunition. I compete in 1,000 yard high power rifle competitions. Consistency is key, not only in training, but also with the rounds going down range. Anyhow, my preference is 200 grain Sierra boat tail match projectiles. And this propellant seems to handle the heavy bullets well from my custom Remington Model 700 in caliber .300 Winchester Magnum. =)
