I have 2 of the afore mentioned U.S.44 Mossbergs, fantastic offhand plinking rifles and casual target shooting.
If I was going to enter target shooting matches the following rifles would be the ones I would chose, plus it would all depend of the type of target shooting being done. Winchester 52, Harrington & Richardson M12, Kimber M80, Remington 540XR, and possible the Schultz & Larsen model 70.
