how do you measure barrel temperature in a reliable manner?

[QUOTE="ATH, post: 2293036, member: 1656"] I don't. The issue is irrelevant for hunting rifles, I simply take my time on the range so heating is never an issue as when I hunt the gun will be cold so I want important shots to be representative of that condition. With high powder capacity rounds I'll take 3-5min between shots. I see a lot of unsubstantiated assumptions in this thread, like barrel temp affecting MV. I shoot F-class and on my first string with unlimited sighters it's typical to put 25-30 rounds of 284Win down range in 15 minutes. Granted it's a 1.25" cylinder barrel but I can't touch it when I'm done. If MV were increasing, at a 1000yd event, I would have to start taking elevation out of the dope as I progressed and that's not typical. Also that heating invariably leads to flyers with light barrels. That's gun-specific. I do have a couple hunting rifles that climb when they get hot. I also have a 338 Edge which I shot a match with from 1000 to 2000 yards in a manner where the barrel got quite hot, and there was non stringing. I once gave a cheap 22" .243 Savage take-off barrel to a friend, who slapped it on an action and shot a 600yd F-class match with it. That thing was red hot after a 30-shot string (with sighters) but there was less than an MOA vertical dispersion on the target, and no pattern between early and late shots. [/QUOTE]
