Savage O/U? Handy. Having owned one of the 22/410 versions... I feel like the 22rf/20 gauge is quite a bit more versitile - I think they still make the Camper model, which is handy for packing. The only one I have at present is the 223/20 - OK for coyote calling and maybe turkey and it has a 1-12 twist 223, so no heavy weight bullets :-( Shoots slugs like a dream, but over all it's a bit hefty.<br><br>Back to your question - as far as I know, 410s are normally choked full and dedicated slug barrels are normaly cylinder (no choke). Since there is so little shot in even a 3" 410 shell, I would imagine that opening up the choke would thin the pattern out too much - I would leave it alone, especially since 410 slugs are very wimpy - I believe you would lose more versitility with shot than you could ever hope to gain with the slugs. If it will keep slugs on a paper plate at 50 yards, that should be good enough.<br><br>Again, if you have not already purchased the weapon, I strongly suggest the 22/20 gauge instead - it's a heck of a lot more capable, especially with 3" magnums, and you can drop all the way down to really light upland game loads that hardly kick. I think those are normally choked modified on the Savages, although I could be mistaken - and I think the Camper is probably IC, which would be my choice anyway.<br><br>Hope that helps.<br><br>Tom<br><br>
