Re: 6-284 long range antelope load
My 6mm-284 is a dedicated extreme range rifle and set up as such. Heavy tactical stock, 30" Lilja 1-8" stainless fluted barrel.
I shoot the 107 gr Sierra Mk at a tick under 3600 fps. I have loaded the 95 gr Ballistic Tips to 3800 fps but at extreme range, 1000 yards and beyond, they do not run with the Mk.
I use 56.0 gr of Rl-22 but this is a very top end load. I would start at 52.0 gr or so and work up with a 100 gr class bullet which includes the 95 gr BT.
I would have to agree that Varget is an extremely fast powder for this round and heavy bullets, well any bullets for that matter. As is IMR-4064.
In a round like this, their pressure curves are just to steep. You can go from a max load one day to a VERY hit load on a different day under different conditions, especially with the 4064 powder.
Varget is a little better as it is less temp sensitive but your still playing on the edge in my mind.
What kind of load density are you getting with Varget? It can not be anywhere near 85% and still be safe.
