Posted a similar question in another forum but don't see any responses and I'm an impatient fellow.
When reading posts or articles about rifle load tests, one almost always sees notes about how long the barrel was allowed to cool between shots and groups. When reading about handgun load testing, there is rarely if ever any mention of letting the barrel cool. Does barrel temperature, and changes in that temperature between shots and groups, not affect group size and/or POI in handguns as much as it does in rifles?
