I would say you are wrong on this one. I will agree that they are few and far between though. Because of the loose powder and vast bullet selection for an inline it is easier to fine tune a load, much like handloading for a centerfire. The problem is I bet most don't bother with it. They find a load that shoots reasonably well and just go with it.

The modern loads for a 20 ga shoot the exact same bullets a .50 cal inline uses, they have simular twist rates and shoot them at simular velocities. I have seen some that are very accurate, like sub MOA at 100 yards. And I have seen several 12 gauges that will shoot 1 inch groups at 100 yards, with a heavier bullet at the same speeds or faster. The problem is the expense of finding the right load.

For target shooting and pure accuracy I will agree the Inlines still have the edge, they are great weapons. However for hunting a decent slug gun with the newer loads is more than accurate enough to kill deer at 100 yards and beyond, and is easier and more convenient to shoot. Not to mention easier to clean.

I hunt with both, I have a remington 700Ml and an H&R ultra slug gun. Both will shoot one inch groups at 100 yards. The 700ml is a deadly weapon out to 150 yards, but so is the slug gun for the most part and is much nicer to shoot and maintain. Not to mention easier to get a second shot off if I had to. 5 or 6 years ago the inline was the better weapon hands down, but the slug technology is catching up fast.

Heck my H&R will shoot some cheap 2 dollar rifled slugs into a 3 inch group that measures less than 2 inches. That is 3 shots into one large ragged hole.
