I now believe you are correct. Early howitzers were often smooth bore, and fell somewhere between “guns” (rifled) and mortars (smoothbore). By WWII even the howitzers were rifled.

It is my impression that the barrel of the M115 (8" howitzer) is not a smooth bore, but rifled.

From TM 9-1300-203, page 2-143:

"The projectile [8-Inch: HE, M106] consists of...and a gilding metal rotating band."

If there is a rotating band on the ammunition, I think a rifled bore is implied.

Mortars are often smooth bore.
