Hello! Long time reader, first-time poster,
I'm finishing my build for a .300 blackout AR and I finally got an EoTech XPS2 300. As I prepare to purchase ammo for it, I'm trying to find information from those before me.
Is there a recommended ammo grain for using this optic to maximize accuracy for the two dots?
If I zero with 145g will that have an impact on the subsonic round used? i.e 145g with 20g Or if 150g sonic is used, I should use 220g subsonic? Or does it not matter at all?
Does the grain of round determine the elevation difference for the 2 dots used when swapping sonic to subsonic? If I can only zero to one round, say the 145g, how do I know which sub to use in order to maintain the proper zero with different ammo.
I hope I'm explaining this constructively, please ask questions if this isn't making sense but I have not found anything online about this. Maybe it doesn't matter at all?
Thanks, everybody!
