Help- Hop Substitution

Hey all...

So I'm going to be brewing a 1-gallon batch of this recipe:

https://www.homebrewtalk.com/f68/left-hand-milk-stout-clone-139820/

I've got everything for this but totally forget to get the Magnum hops. Because this is only a 1-gallon batch, the ingredients in the link above have all been divided by 5. Therefore, I literally only need 0.07 oz of the Magnum hops. Because this is such a minute amount, can I get away with using any of the following instead?

-Cascade
-Mt. Hood
-Willamette

Thank you!

Mt. Hood is the highest in alphas of the hops you listed, but only about 6% vs. the Magnum's 12%+.
Because they'd probably be used for bittering and boiled for 60 minutes, any of these would work, since a 60 minute boil will pretty much kill any real flavor or aroma... You'd just have to adjust the weight of hops that you add to achieve the proper IBU's.
I'd really urge you to try to get some higher alpha hops if at all possible, Target, Sterling, Apollo, Perle, and Horizon come to mind as good subs.

but how much additional Mt. Hood would I need to add to achieve the effect of the Magnum?

Use an online beer calculator such as hopville.com and play with the numbers until you get an equal amount of IBU's from your substitute hop as you got from the amount of magnum in the recipie.
