Nope no questions. Thats proof enough for me that no harm will come of it (pouring water down the barrel).
Definately sounds like talk from experience, and a good method you have come up with to keep the barrel cool/clean, thanks ackleyman.
Apology for the smartazz remark...just that I work a little bit with metals and have been skeptical of barrel cooling methods other than just giving it time.
It`s not like the barrel will be red hot.
Advice taken.
