Shoot a 3 shot string, one right after the other, just like you would in a hunting situation, then check your groups. Let the barrel cool completely, 10-15 min, after that before shooting another string. You aren't going to let it cool in the field between shots.
Amen.
My technique exactly.
Just used it two days ago shooting one of my Duces; three shots one right after the other, then a 15 minute break. And midway betweeen barrel cleanings, I shot one of the best groups I've shot with an old Rem 722, a .280 at 100 yards.
