Some things just work....and I'd stick with it.

The 30 cal 1-10" twist although a 1-12 will do fine as well.

On the 7mm I'd go 1-9" but you could easily go with 1-10" as well.

There's little to no advantage to go to a slower twist even though it seems there should be!

The best 30 cal for elk and smaller is still the 30-06 but any of the mags you mention will not let you down.
