Effect of Suppressor on Hand Loads

[Chranah]

I'm not in the suppressor game yet, but seriously considering it and I have some questions:
1) Is it okay to have one suppressor for use on a bolt gun and for a gas gun? Are suppressors even designed for those considerations?
2) I'd like to suppress my 7mmRM bolt action hunting rifle and my 6mmARC gas gun. Will one suppressor work for both?
3) I hand load all of my ammo. I've read that a suppressor will cause more pressure and fouling in gas guns. Will I need to reduce my loads when running the suppressor, or will closing my gas block a bit more do the trick?
That's about it for now, but as the conversation progresses, I'm sure more will come up. Thanks in advance.

I forgot to mention, I've looked online, but I'm tired of everyone just telling me why THEIR's is the best and why I should buy it. I want to know long term effects on my rifles. I'm not even looking at make and model yet.

One will work for both, but they make flow through suppressors for gas guns that don't have as much gas coming out of the ejection port into your face. Generally these don't suppress quite as well, so it's nice to have 2.
Generally you'll need to turn the gas down a bit with a suppressor.
There are no long term effects on a rifle other than you'll likely shoot them more.
