CW Minie Ball ID

[cmthunder]

Found this Minie ball at CW site in Western Md. It has a solid base and raised ring.
I measured it as follows;
D-.511
L-.895
22 grams=339.512 grains

The closest thing I see is # 59 in McKee book.
Pope type for false muzzle rifle.

Can anyone confirm and Or ID otherwise?
Thanks

A minie ball by definition must have a hollow base, but it may still be CW. Cannonballguy will give a positive ID. Possibly an early post war 50-70 cartridge slug.

Gunsil is correct... by definition, a Minie-bullet must have a cavity in its base, and speaking more specifically, that cavity must be large enough to help the base expand outward into the gun's rifling-grooves.

Unfortunately, your bullet does not appear in any of the various civil war bullet reference books I own, nor have I ever seen your bullet's form before. It is "close" to a super-rare variety of .52-caliber Sharps bullet... but your diameter, length, & weight measurements prove it is not that Sharps bullet (see "Handbook of Civil War Bullets & Cartridges" bullet #116).

It also resembles a .50 cal Smith or .50 Smith Gallagher Carbine but the measurements are off as well. Same handbook as above #73 & 74.
