The main reason for a heavy barrel is the reduction of barrel harmonics. Heavy barrels in general can be more accurate, and should be more accurate. But a thin barrel can be just as accurate if made, and reloaded for properly.

I do not know if a heavy barrel will displace heat any better. But it does take more shots to heat the barrel up. And heat will affect the harmonics of a thin barrel faster than they will affect a heavy barrel. Tom.
