I have a Savage 99 that easily holds 1 moa for 3 shots. After that it starts walking badly. Since this is a big game rifle it will never shoot more than three shots. A ten shot group does not tell me what the load or I can do. It does tell me that it walks after three shots but for its intended use that information is totally useless.
My long range competition rifles or my prairie dog rifles need to hold well under 1 moa in from cold to very hot and yes that is under field conditions.
Test it how your are going to use it.
