Another vote for reloading if you don't already.
In the case of your 6.5 swiss:
Primer: 3.5-4.5 cents depending on brand
Powder: Around 40gr (36.00 divided by 7000gr/lb = .005 x 40 = .20/round (

Bullet: Even 40/box of 100=.4 ea. (you can buy bullets for about 60% of that)
Total: .64 ea x 20 = 12.80/box Using less expensive bullets could drop another 6-8 cents per bullet off the price as well, but keep in mind these are just rough figures using an average of load and price of components to give an idea of cost.
Some people don't like reloading, I enjoy it. You can amaze yourself with the accuracy you can achieve by trying different loads; every rifle is different. Don't have to spend a fortune to start, either. Lee sells an anniversary starter kit for under 150 bucks and Lee RGB(really good buy) two die sets even come with a shellholder.
I'm no expert, but have been reloading as long as I've been shooting. If you have any questions if I don't know the answer I'm sure someone else on here will. All that being said, some simply don't enjoy reloading, so it's not for everyone. It's really almost another hobby unto itself, but it beats watching reruns on cold winter evenings.
