None of us have bought reloading supplies before the rifle, have we?
On my reloading bench right now I have 50 pieces of new Hornady .35 Whelen brass, my press is set up with Hornady Whelen dies, about 125 pieces of .30-06 brass have been resized to .35 Whelen, there are several boxes of .35 rifle bullets and a pound of Power Pro 2000 MR.
I currently do not own any rifle chambered in .35 much less a 35 Whelen.

I have .284, .358 Win and 416 Rem Mag brass.
Have no rifles in those calibers.
OP, if you were hoping for a consensus this thread has not helped.
Which caliber scratches the bigger itch?
You can always add the other later.
