If you plan on doing a lot of shooting, with your 7mm-08, then you would surely save money if you reload.
Myself, I don't reload, and I don't do a lot of shooting with my deer rifles once I have them zeroed in!
Price of ammo isn't a factor if I like the round I'm shooting, and it's a caliber I have confidence in, and it's my primary hunting rifle.
I hunted for years with my sporterized British .303 and I paid nearly $30 a box once, and I never needed more than one box at a time, and one box of ammo 20 rounds, would last me a couple seasons, even after firing a couple shots at the range to make sure it still held zero.
So if your looking for a plinker, and hunting rifle combination, then yes you might want to look at something more economical, but even at almost $10 a box it might be better to choose a rimfire, or get into handloading.
Look around for the best deal on ammo, as I found 7mm-08 ammo just last week at one of the chain box stores (Academy sports & outdoors) here in my area that was $16 a box and some change, for Remington 140 grain core-lokts.
