It sounds like you may have a bedding problem or the barrel is heating up.
What you have is a good hunting rifle but not a match rifle (One or two shots are all
you need) .
Check the ES on the first two and if they are way apart it is still a load problem , but
may also be bedding and or heat.
You can verify this also by shooting one shot and waiting 10 to 15 minutes before the next
shot is fired.
If conditions (Wind,Temp ETC) have not changed the groups should improve if its the bedding.
