I guess I'm bored. Looking online at www.midwayusa.com (I just happened to be on their site because I was buying a scope there) a box of Federal Power-Shok in .243 Win is $13.29 (either 80gr or 100gr) and a box of Federal Power-Shok in .25-06 is $21.99. $8.70 a box times 5 boxes on a good afternoon varmit shooting and that's $40 more expensive on the .25-06. I'm sure it wouldn't be that much more if you are reloading your own though.
