No, not if it's a 22-250 like that post suggests, since the last paragraph of the article states;

"He recorded a narrative verdict of unlawful killing, adding that Rifleman Lincoln was shot by enemy fire. "He sustained a single gun shot wound to the head,' he said. 'This 5.56mm, U.S. manufactured round was not fired by friendly forces."

That might leave the possibility of a .223 nominal diameter [projectile] handload? I don't use .22-250. Is it .223 diameter projectile?

Wait a minute...the article said the imvestigation findings were Lake City Armory.

So we can forget about handloads, or 22-250's, I guess. If the investigation was correct. I doubt the British would make such an exact "Lake City" claim, if there wasn't some basis for it.

We didn't get a weight, just a caliber. .22 caliber barrels are used for a wide variety of cartridges. Barrels are rifled in ranges from 1:7 to 1:14. Heavier bullets require a faster twist. The 5.7x28 uses 32 and 40 gr. The .223 market uses 46 to 80 gr bullets with 55 gr FMJ being most common. The military likes 62 gr in 1:8 barrel. The 80 gr needs a 1:7. You can get a look at the variety of .22 cal rifle bullets at this link. The same bullet will work fine in a 22-250.

The source of the bullets and rifle is irrelevant. The problem is the person targeting the British soldiers. Proving that the same rifle was used in each case means it is likely that there is ONE person to track down.

The rifling pattern might be enough to make an educated guess about the manufacturer of the rifle. Rifling can spiral in a right or left direction. The rifling can be created by cutting, button rifling, or by forging the barrel around a mandrel. Each manufacturer has a particular technique. S&W uses a "gain twist" rifling that rotates faster at the muzzle than at the breech. The value in that approach is less deforming of the bullet.

That might leave the possibility of a .223 nominal diameter [projectile] handload? I don't use .22-250. Is it .223 diameter projectile?
