I believe all 657s had smooth triggers...
Yes, the 657MG was a pre-IL. The later 57MG had the IL....sad.
Shooting out in Idaho was beyond fun... Mackay posted pictures of the 780 yard target a short time ago.....it was a long way off... The year before I only had a 57 4" out there and we shot out to 500. Mackay never had shot DA at long range and once he did he became a believer. As Lott said, it keeps a strong even pressure on the gun each shot until the shot breaks.
