Sorry to sound so stupid.......but what is the difference in the rifle when manufacturers call their rifle 'Varmint'? Some call their rifle 'Sporter', and the only difference i can see in the stats is barrel length.
I think varmint versions are for lots of quick shots and they have heavy barrels so they are not a prone to losing consistency when over heating. Its a US thing, shooting dozens of prairie dogs! In the UK they are more used by the target boys.
Sporter is for e.g. deer stalking where you might only fire 2 shots all day - one shot to check the zero and one at the animal, so over heating isn't an isssue.
Like snowstorm says the barrel is alot heavier than the sporter.
I was after a varmint rifle but after trying both decided that carrying a varmint stalking for hours wasnt practical.Thats just my opinion.
like wise, l have a remmy police .243, great for high seats and sitting out for foxes, but carrying the thing, it feels like my work .338!!!
So l have just recently bought a ruger m77 mk2 for woodland stalking much lighter, brings up to aim quickly, is a joy to shoot. All be it not so accurate but do you really need 1/4 moa when almost all your shots are between 50-150m?
I believe the new objective will be having a lightweight accurate rifle.
One way of achieving this is chopping the barrel length of a varmint rifle and adding a lightweight scope, mounts and stock. This can add up as being lighter than a sporter.
One can save 1 lb on stock alone, half pound on say a-line swarovski compared to a steel swarovski or schmidt.
