It helps when you text me! haha.
IMO, heavy bullets benefit all around in long range. The only downside is they are slow at the start, but hold more speed, more force, and less wind drift at further distances. At 1000 yards you're pulling over 1000 ft-lbs. Your velocity is also now higher than a 178-180 because of the superior B.C of the heavy grain bullet. (for most bullets anyways, 208AMAX's are ~.630). I launch mine at 2500 FPS. I could push it up to ~2700 FPS but feel no need.
The furthest I've taken it out was 1100yards because of maxing my scope adjustments (action is angled), but it does it without issue. Once I get a 35-45MOA rail I'd have no issues taking it further. (my ATRS rail is on my work desk in front of me right now, awaiting to be modified)
I think they are worth a try. I don't shoot the bullet you are asking about, but I'd try the 200gr and see what results you get and have a enjoyable experiment. Just make sure to match with the proper powder. Heavy = slower powder.
