“Really Odd Looking” Enfield Bullet

For your consideration one “really odd looking” Enfield bullet. This bullet is in good dug condition…I have pictured the best side of this bullet. This bullet is complete with a couple gouges, a rounded nose & a really odd base. Notice the small opening at the base of the bullet & just inside there is a larger hollow cavity but I cannot tell what kind it is…my best guess would be a flat bottomed cavity possibly a plug/cylinder type. Measures about 0.56 x 1.04 inches. I see nothing that would suggest this is a fired bullet. Looks to be a Thomas RBRF#4 633 possible “Austin, TX” bullet.
