Also, I might add that the temperature stability of the shooter needs to be added into the mix. If you aren't comfortable, the overall rifle/ammo/shooter accuracy is affected. I bought some LL Bean Merino wool underwear, and the synthetic Thermax underwear I wore for years has been relegated to the old rag bin. Paying $120 for longjohns may make you cry, but you will only cry once. That's a bargain basement price for what others charge for similar quality. Wool has a thermostatic quality that no synthetic fiber can match, quality Merino wool does not itch at all, and it gives temperature stability to the shooter himself. And that's where accuracy begins.
I remember when I was in Russia, and a Russian woman told me how they tried our modern western synthetic fabrics, but they got tired of freezing and just went back to using wool, furs, and leathers for winter clothing.
Lesson learned: take care of yourself first, then worry about the technical rifle/ammo BS that most people here ponder over to absurdity.
Take a look at the top military sniper list, and see how about 98% of the top 100 were Russians. They had equipment that was effective, not fancy. Go for effective over fancy and you will do OK. This means that if you have a large collection of articles from modern gunwriters, you don't need to buy toilet paper for quite some time.
