One thing I can't understand is that with today's high tech slugs, people still using 26"/28" field barrels with slugs, then drill and tap the receiver for a scope, we have three guys in our camp that do this, all three using rifled slugs none of them able to get decent groups at 50 yds, I even saw it at the range last month and last week from strangers. I do my best to explain to them the benefits of using a slug barrel (smoothbore or rifled) if your going to use a smoothbore at least get one designed for slugs, or better yet get a rifled/cantilever barrel
