i tried some hornady 357 180gr with the mmp blue 357/45 sabot. that bullet did not sit well in sabot, the best group was about 3/4" 3 shots @ 50yds. i ordered the lee mold 358-200rf which has a base for a gas check so it might sit better in the mmp sabot. i have 2 kodiak 45's one magnum and pro mag, i got 2 to have a parts rifle. i have been working on stoning the trigger/hammer sear and got the triggers down to a decent pull. then a trigger came up on ebay and i grabbed that one.
