Best Hunting Bullet past 300yds ?

[Bassfish1952]

I have not tried anything beyond 300, the 103 would be one of my choices too.
Berger has a 105 Vld hunter that I can get to 2720 in my 22", it keeps 1000 ke to 425 yds.

But that seems like a "fur piece" if you know what I mean. Personally I'd use one of my Creedmoors at those distances, either 6.5 with 130-143 gr, or 6mm Creed with that 105 berger, 2950+ and not pushing it too hard, gets out to 525.
In my long pipes one (paper) exercise I do is to evaluate which loads could do an antelope at 425 yds (the closest distance I've seen them before they start to move) and the creeds are the go-to ones for that type of hunting out west... for me.  I want to stay in the short actions, at most.

Thanks 

I'm trying to stay with the 6arc, I really like the gun I have , with the 24" barrel I think with a lot of practice I should be good to 400-425 . I have a couple of nice 6.5 CM's  so next year I'm going to work up a load with the 103 ELDX or something like it to try in the ARC and take my CM along just in case. 

It seems to me the factory ammo is a little below what's on the box , I clocked some at around 2750 and am looking at maybe being able to better that with an accurate load and will be taking a popup blind along to maybe setup instead of using their blinds . Don't want to out shoot what I am capable of but still like to bring home some meat .

I'll look at the Berger
