I will agree with the 165-180 grain heads, there re so many GOOD one's out there today, and loaded in countless factory loaded ammo offering
the ONLY way your going to find the most accurate one in YOUR rifle is by shooting them and seeing what YOUR rifle likes
that's just how it works, what one rifle likes another might NOT
so, there is no way for us to tell you BUY THIS or THAT
it all comes down to what YOUR rifle likes and to shoot at 350 yards takes some practice its not like on TV where you buy "X" rifle/AMMO< and magically are a good shot far away, all the more so in the field hunting
so, PLEASE before sending rounds at deer , make sure your skilled enough and have the PRACTICE proving so, from your rifle at what ever ranges your going to shoot at them in the field hunting!
just cause the rifle and ammo are up to the task, doesn't mean the shooter is, be honest with yourself, no one here is judging!
ain't no prize for wounding/loosing game!
