Both the 4th Tennessee and the 22nd Tennessee Companies were from Gibson and Hardeman Counties, so it's possible both entries refer to the same man. See the following:

Co. "B", 22nd Tennessee Infantry was called the "Hatchie Hunters"; Co. "F", 4th Tennessee Infantry was called the "West Tennessee Rifles".
The 22nd Tennessee was consolidated with the 12th Tennessee. The Tennessean pictured on this 12th Tennessee site presents his musket so the lockplate can be clearly seen. He has the hammer in the half-cock position. The soldier's jacket also has some interesting black (or dark) trim on the sleeve and collar, and his hat looks great!
