Since my range trip last week I have pillar bedded my 457 MTR. Here is last week and today on the same card. Ammo was the same lots shot in the same order. Overall consistency is improved, average group size is slightly smaller and I had a couple of the smallest 50 yd groups to date. Overall I feel the effort was worth it. Next up will try various torque settings on the action screws to see if that makes any difference/improvement. CZ says 25 in/lbs on wooden stocks and 35 in/lbs on stocks with metal pillars so will start at 20 and incrementally work my way up to 35 to see what happens.
