I believe the clerk was in the wrong for not selling him the slugs, and I seriously think he was full of crap by saying that it will destroy the barrel after 10 shots.

On the other hand, I will NEVER hunt with rifled slugs out of my Winchester 1300 with a rifled barrel, not because it will tear my barrel up, because it will not allow me the accuracy I require of my hunting set ups. What I suggest you do is to get a good bench set up and buy a couple boxes of different rifled slugs and a couple of boxes if sabots and shoot them off a good bench and see what kind of accuracy you get with them. But please don'tjust shoot 2slugs and stop, what I've found is that rifled slugs in a rifled barrel just simply won't repeat groups and they aren't as consistant as sabots. If you're happy with the performance of the rifled slugs, then I guess go with them. But I'd almost betcha the sabots groups will be much more impressive and consistant than the rifled ones.

I understand that damn-near $20 bucks for a box of 5 slugs isout of hand and rediculous(which is why I hunt with an Encore 209X50 but that's beside the point). Something to consider, I've got 2 buddies that threw their rifled barrels back in the cabinet and grabbed the ole vent ribbed barrels and went back to rifled slugs because of the price of sabots. Put a improved cylinder choke in the thing and you're good to go out to 100 yards every day! Something you may want to think about.

I hope I've helped! Good luck!
