SO I have a new 6.5 creedmoor. Yeah, it's a Tikka and I drank the Kool Aid but now I need to know what the benefits of the heavier projectiles are!

I'm mainly shooting gongs out to 700 yds at the moment. Well, I'm hoping to get out there.
Most of my shooting has been out to 500 with a .223 and mates 7mm08 so I want to go further hence the creedmoor. So assuming they all shoot in my rig, will the heavier projectiles be of any benefit over the 123 ELD-M at that distance?

So, lets say there is 15-20 mph from 3 o'clock.... is the weight v speed a relevant argument here or is it only out past that point?

Here's a couple of screen shots to to show bigger BC equals better performance at long range

first is for hornady factory load 129sst superformance doing 2923 at muzzel 15mph from 90 degrees


2nd is for 147 ELDM doing 2690 at the muzzle same wind


The rest is self explanatory

Oh and the numbers are for my 6.5 CM 24inch barrel
