I shoot high volume 20's & 22's......not rimfire

In a hot p/dog patch where you can ran 65-70 rds an hour

This is not uncommon...A wet Sham Wow rag can aid in cooling

Mostly for a break......push a patch or two every hour or so

Get your spare rifle & let the hot one sit in the shade...upright...chimney effect

Have barrels with 10K+ rds and still shoot 1 MOA p/dog

Some barrels shoot good dirty & hot
