Hi,
I am 6.5-284 fan, and have used it for many years as my main hunting calibre with extensive developments with various projectiles.
Depending on the range and size of animail will be a deciding factor.
I liked the 129 - 130gr range, however have moved to the 143 - 147 range because of the high BC's as we speak.
They are both good bullets, performing well, where I have taken a few deer up to medium size to 500m so far, goal is 700 - 750m.
Head or neck shots, no probs. Shoulder or just behind, furthest shot deer, have moved a couple of bounds then droped (30m) max (deer taken over 350m). So anything under 350m wasn't/ isn't a problem.
I have both at the same velocity, 2960fps out of a 26" shillens match. Sub 1/4 moa @100m. A bit more recoil than the 129/130 range but managable.
My managable - I like it when I am still observing the target/ target area when and after the shot with minimal scope jump/ movement. There is a little, where I am slightly off target, however acquire agan with a little shift.
Like the performance so far
Hope pic displays, red stage.
