Thanks for the interest Arizona.
Here's my 6mm dilemma thread:

I have also looked at some .30 cals - namely the .30-06. Since it and the .270 and .280 are pretty much in a ballistic heat, most say take your pick. I like the idea of the .280 so that's what I am probably going to go with.
Yes, I know that bullet selection may be marginally better in a .30, but for what I will be hunting,I doubt it will matter. You can get quality 7 bullets all the way up to 175 grain (maybe even higher) and I think that bullet is going to be able to take down anything I might point the barrel at.
As far as the .204 ruger, I think I am going to get one. I don't think components will be hard to get for it at all. Sure, buying brand new brass may be difficult right now but I haven't found it very hard to find ammo right now. And if I have to be the one to make it into once-fired brass, well, I guess that's my cross to bear.
