I got a call from a friend that was buying his brother a new Remington 870, he wanted to know if he should get the 28" or 30" barrel.
I figured that since it'll primarily be used for waterfowl and he won't be carrying it on long hikes he should go for the 30" and gain a few more fps.

Did I give him the right answer? How much difference will 2" make.

Thanks guys.
