Re: 6.5x284 vs 7mmWSM
I like them both even though I do not have a 7WSM. For deer/antelope you can really just flip a coin, but don't make the mistake of choosing a short action if you are building a 6.5x284. This is a 3.10 cartridge. The short action is a 2.80.
I would also take a serious look at the 6.5WSM mentioned. I have a Krieger 7mm bbl in my safe. It is stainless with a 9 twist. Not sure what it will be but the 7WSM has been a consideration. Also looking at the 7mm Dakota. Knowing me, I'll likely just build another 7 Rem Mag though.
I like the 130 accubond for the 6.5
