HDW - Tikka and Sako have made rifles specifically for this purpose and are use by some countries' military snipers for years. Unlike your response, I did say that Remington or Savage weren't good rifles for this or other purposes.
I think you'd find very few people who've owned and used thise rifles to agree with you slam on them.

The military issues a number ofweapons that have synethic and compositeparts in specific areas of the weapons to save weight. And frankly, for certain applications, synthetic/composite can be designed to have characteristics that hold up under tough use in all sorts of conditions better than standard metal parts.
Rifles that consistently shot groupings in sub minute of angle in the hands of an experienced marksman are something to be take seriously.
