I've been torn between rifles, I was gonna buy a m700 PSS but think I'm gonna do a AR first and wait for a new 5R next year. So the rifle I'm looking at is a YHM diamond. It has a 11.25 twist and 5R rifling. I could us some input about barrel size 16 or 18. Its chamber is 6.8x43 so it'll shoot the new rounds as well as the old. I definitely want a sub MOA gun so if you can help it will be great.
