And you still need a looooong barrel and a fast moving plutonium part (see the thin man design on wikipedia and then extrapolate from there) even creating near close enough pure plutonium since economically you won't have pure.
- bayouborne 4y ago"Parsons’ first order of business was the plutonium gun. Because it needed a muzzle velocity of at least 3,000 feet per second it would have to be 17 feet long. It should weigh no more than a ton, a fifth of the usual weight of a gun that size, which meant it would have to be machined from strong high-alloy steel. It would not require rifling but needed three independently operated primers to make sure it fired. Parsons arranged for the Navy’s gun-design section to engineer it." - Richard Rhodes - The Making of the Atomic Bomb
