Hello everyone, I'm new at this forum. I have heard about the 375-408 Cheytac, and I wish to gain more information about this caliber. So I have a few questions that I hope you can answer: 1. When does the 375-408 get subsonic? I have heard that it remains supersonic out to 3000 yards, true? 2. How is the 375-408 affected by wind compared to the 50BMG? 3. What is the bullet drop compared to the 50BMG at 1000, 2000 and 3000 yards? 4. Can a good marksman shoot smaller groups than 1/2 inch at 100 yards with the 375-408, or is it ammo-limitations that prevent this? 5. Can the CheyTac M310 be ordered in this caliber?
