Sure,a shotgun with a 3" chamber will fire 2.75" ammo just fine.
I wouldn't choose a .410 for shooting big hogs, but it might be OK for smaller ones if the gun is accurate and shots are 50 yds and under.
Thank You, UncleNorby. I guess that means the 2.5" shells I was eyeing aren't going to work, eh?
