Prvi Partizan Ammo 30 Carbine 110gr FMJ 50 per box

I shoot these out of a ruger blackhawk.
Ive never seen a pistol cartridge penetrate like these do.
But technically, they are not really a pistol cartridge.
I stacked two 4x4 treated posts for 8" of thickness so i could catch a bullet and check expansion.
All i found was a pencil size hole drilled through both posts, bullet kept going, looked like it never deformed when it left the last post.
May need some more 4x4 posts.
