help with few bullet id

[Dfx]

First i do have the handbook of civil war bullets and cartridges by James Thomas. This book has help me several times in indentifying the not so normal minie balls. Anyways i have a couple of bullets that has me stumped not sure if i am close or not. The 2 smaller bullets measure little over .38 with length of .52 and wieght of 108.

The larger bullet i cannot get a true diameter. but L is .75 and W is 262. you can clearly see the black powder still inside..
any help would be appreciated thanks

Its hard to tell from the shadows but from the profile the 2 small ones look like early Colt or Adams but the measurements don't match and I believe the large on is a Burnside.

thanks.. the measurements is what has me thrown off also. they were water finds so im not sure if they rolled around and thats why measurements are off
