Thinking of getting a Lyman sabot slug mould for my shotgun (20 gauge) as $1 to $6 @ ($5 to $30 box of 5) is too much for ammo. When I read the searched threads I noticed that some people have a problem with that slug cutting the petals off of the wads at the base of the slug. Shouldnt a harder alloy prevent some of the "flex" of the slug when shooting? At .57+ dia. I wouldn't think expansion on target would be an issue. In fact I want the thing to penetrate max with that .57 wound channel. Should slug be 20/1, 30/1, linotype, W-W, quenched W-W, heat treated W-W, or some other harder than PB alloy? Any info on the alloy question for this slug would be welcome. Anyone have a 20 ga Encore SS fluted rifled barrel and can give me insight on what will shoot good in it would be appreciated. Now it shoots Lightfield and Winchester Platinum pretty good. If I can't shoot any cheaper than $1 @ I'll have a 20 gauge Encore Pro Hunter SS fluted rifled barrel to sell soon. Thanks, 10 ga.
