When I first shot 98K, my shoulder hurt unbearably after firing 5 rounds, and after firing 10 rounds, my shoulder hurt for a week. But now, a few years later, no matter how many rounds I fire, I don't feel any pain. This 98K should be a Russian captured, and it looks like the bolt is not very smooth.
