Spent a little time with JJ Perodeau Wednesday while he cut my Merkel for a red dot. He advised to shoot both barrels within 15 seconds. Shooting right barrel then looking at target thru spotting scope gives that barrel time to grow from the heat and effects left barrel POI. Made sense to me. He recommended two targets. One for each barrel side by side to help with identifying which hole was which.
I know very little but it made good sense to me.
