John,
the short answer is...yes, they are heavy and..no, I wouldn't care to drag one around all day. In addtion when I put one on an Encore frame it is usually with a whole lot of scope and a custom laminated thumbhole stock.
Can you say....<heavy>?
Lot's of fun to shoot from a bench or a rest as long as it's not far from the truck, but if you gonna tote that thing all day, get a Rynite stock and a sporter barrel, for the first couple of shots they are generally just as accurate.
