There’s no way to know the shot came from THAT firearm.

Yes there is. They have the bullet, they have the gun. Ballistics fingerprinting would be quite simple.

[mamelukesabre]

no it wouldn’t. there’s no rifling marks on a black powder slug

[redgolum]

If it was a sabot round, it won't be that easy. The grooves from the rifling will be on the spent sabot, not the bullet.

A muzzle loader doesn't have a rifled barrel, not as simple to fingerprint as you think,and I'm being nice, not to mention the muzzle pressure needed to send a round 1.5 miles is absurd. No mention of caliber. All nonsense, muzzle loaders in Illinois never required any sort of FOID bs, now they do.
