it has been back to Remington it had bout 150 max I would guess down the tube then they shot it the grouping tolerance must be and inch and a half i shot 2 3 shot groups of all my factory ammo so maybe another 50 then tried 150 max handloads this winter I live in Minnesota so its a little cold and snow to do much bench shooting I can match and maybe improve accuracy with my handloads best groups where around 1.25 with 4064 and 53 sierra matchkings and 55 varmaggedons I have tried 4064 h380 4320 varget 3031 4007ssc h4895 people told me to slow it down to 3600 I was mostly loading for 3800 range is I went slower like 3600 it was terrible like 4 inch groups the throat hasn't moved since I measured it after 200 rounds or so
