Thread: POI shift when a barrel gets heated up?

i think its pretty standard to get groups open up as the barrel heats up. feel the barrel, let it cool down a bit and go again. heavier the barrel the more shots you can generally string together. once i have fired 3 or so shots i generally wait to its luke warm to the touch then carry on, gauging barrel temp as i go. thats my take on it. i think custom barrels dont seem to open up as much with strings of shots from what i have seen.
