Try this ammo out. Here is link a linki took my 300 rifle to the range today and verified that i was dead-on at 45 yards with fiochi 150 grain rounds at 45 yards (max distance for where i shoot). i also fired off five vmax 208 subs and observed two things: the vertical distance between my scope's zero (with the 150s) was 4 inches low and that the subs don't group as well horizontally.
then again...it could be that the freedom munitions 208s with hornady vmax bullets are not an accurate round - at least with this rifle.

I have not had time to set it up but have shared with @Red Dawn and @AirOpsMgr
nice! do you have experience with this ammo/is it legit?
Yes. I found that it stayed subsonic better than Remington and some other name brand subsonic ammo. @Red Dawn really found out when I let him shot some. I never tried zeroing a scope with it but was accurate with a red dot I just threw on the new upper. I will have to remount the scope on the new upper when I have time.nice! do you have experience with this ammo/is it legit?
Yep, that is the stuff. Thanks!I have some and do use it. I was able to shoot it accurately and it stayed subsonic through the Tirant 9s where the American Eagle subsonic didn't. I would recommend using it too.
