RE: Am I Expecting Too Much?
Hey wildman - well you finally came out of the closet??.... just playing.
3"-6" is fine for a smoothbore. But isn't the Pro hunter Encore bbl rifled?
I'd give Federal slugs a try too.
I have an 870 that I have set up for slugs with a 20" smoothbore barrel. I've shot 4 different types of slugs and the most accurate out of mine is the Federal Tru-ball slugs.
