While I agree that thin barrels can be temperamental, & IMHO, usually shoot most consistently being bedded, when was the last time that you fired a gun in a big game hunting scenario with enough rounds & fast enough to heat it up enough to have an real effect? Assuming it was ever good it the 1st place.

Here's a target shot with a Rem 700 Ti 7-08 (pretty thin barrel, around .510 IIRC) that has 9 shots with one bullet & 3 different powders during testing; the action & barrel are correctly bedded, the 9 shots were fired consecutively, single loaded, over a period of maybe 2.5 - 3 minutes at around 65 F.

8 of the 9 shots are in one big hole; I dropped the 9th shot out of the group.

And I have another barrel, same contour, on a 280, that performs equally...........so thin barrels can & will shoot, & heat from firing while hunting is just simply not a issue.................if the gun is good in the 1st place. Not all are.
