Re: will 25/06 powder selections shoot well in a 30/06?
A lot of thoes powders you mentioned are a little too slow (IMO) for the 30-06. In answer to your question, yes the powders optimal for the 25-06 are basically considered optimal for the 30-06. I would skip the 7828, H1000, and the RL22, thoes are generally better suited for the 300WM, 300RUM and bigger 30 and 338 cartriges. For the 25/06 and 30/06 and try some RL19, IMR4064, Win760, H4350, IMR4350, and IMR4831. These are all powders that will work well with the 06 and are in the area of the correct burn rate.
A great way to see what powder might be optimal if you don't have any other information is to crack open a reloading manual. Check to see what poweders are getting the best velocities with the bullet weights you plan to shoot. Start there and more times than not you are starting with a better powder than if you just look at the burn rate chart and pick one.
You might also want to check the barrel length of some of thoes guys posting about their velocities. To burn a lot of slow powder you need a long barrel otherwise you just end up with a big fireball and low velocities. Also what grain of bullet are they shooting? As to why slow powders are better for the 25-06 than the 30-06, you have me there. Perhaps more knowlagable people here can make since of that one.
I hope this was of some help.
