A bit off topic, but this IS the Fire.... blush

Another mono option is the Cutting Edge mono that sheds it's petals.

I've not tried them in anything other than the .308. Here's the link to that bullet. Check out the reviews; I wrote one about a hog I killed. They are accurate

Checking their web site I did find this .338 version that would probably work very well in the Federal 338. It's light enough to move pretty fast and from my experience with the 135 ER in the .308, should have impressive terminal performance.

They are expensive, but how many do we actually shoot at game. My deal, work up the load and save them for hunting. Practice with something else.
