This also depends on what you call a Heavy Barrel.
For example, in factory rifles called a heavy barrel varmint rifle, A Tikka/Sako/Remington has a Heavy Varmint Barrel BUT the same thing in a CZ 527 is in between a Sporter Barrel and a Heavy Varmint Barrel. Accuracy wise, no difference but carry wise the CZ if you want to shoot varmints.
Saying that it is dependent on calibre. A CZ 527 .204R has a longer 25.5" light contour Varmint Barrel but the CZ 527 .223R has a heavier 24" fast twist Varmint Barrel.
Between the three mentioned there is very little difference in accuracy but a lot in price cost.
If you are going to fire off a dozen rounds in the same amount of time then a Varmint Barrel but if you are going to shoot the same dozen over a day then the sporter barrel.
I go varmint shooting and I use heavy barrel rifles, I might shoot 5 rounds in less than 5 minutes or as quick as I can cycle the bolt then change magazines for another rally and if time permits reload the first magazine and go again etc atc... A sporter barrel would get rather hot. Poor Grass Hoppers, then I've got to go and collect the damage and add them to the growing pile I have.
