I usually shoot about 12 or so off of the bench to get warmed up. Then another dozen or so off hand for practice. Then I run through the bushes screaming for 1 mile, also for practice.

I think the Beavertail is just togive you more to hold onto. A lot of Euro shotguns have them, like full length stocks they seem to serve no particular purpose, although a well done one feels fine.

I have one on my 577 because, well just because.
