"I want to make a gentle suggestion, I say gentle because it appears that I have a problem with "crush ribs.""

It is a fact that my Encore does not like Crush Rib sabots: 100 yard groups are all over the place with the 250 grain SST. The Hornady Low Drag sabots with the same bullet make 2-3" groups with that gun-minute of pig. The tight fitting red and the tight fitting black sabots make groups in the1" to 1.5" range with me doing the shooting: A young Marine i know makes .75" groups at 100 yards withthe Encoreand that load.
