Does anybody know if components and roll crimping equipment are available for loading sabot slugs? My Savage 220 is more expensive to shoot than my 375!

Well set up for 12 ga., but no 20 ga. sabots! Good call on the roll crimping tools though. Thanks!

Both Lyman and Lee make (or made in the case of Lee IIRC) 20 gauge slug moulds that are designed to use a standard shot cup for the sabot.

I have the 12 gauge version of the Lee and was not totally happy with it, so if I had to do it over I'd get the Lyman mould but I suspect you could find a used Lee mould on ebay or gunbroker.
