[When it comes to things like my .300 H&H, while it shoots A-Frames very well and I'd think it would show you groups at about 1MOA, I wouldn't bet that the next group I fired wouldn't be 1.5"/100 yards.
Based on personal experience I'd be willing to say that 75% of all folks that claim their big game rifle shoots 1MOA couldn't prove it at a public shoot where all could witness the shooting. Fine groups maybe....but not 1MOA...(1" at 100 yards)
I have drove and met several guys make claims of the one hole groups. Never once could someone reproduce thier claims including myself. I have had wonderful days at the range with 4 sub.5MOA groups and then next week, I am there shrugging my shoulders.
This hobby will drive you nuts.
