Hornady ECX .308 165 gr

Looking to trade these ECX .308 rounds for something suitable for loading 30-30. The box is opened but all 50 projectiles remain, I grabbed this by accident before realizing their not what I'm after.

I'm willing to sell the box for $45, less than what they go for in store. Because of the weight they're probably not worth shipping, but I'm willing to find out the cost if any parties are interested enough to pay for the ride.

Thanks for looking!
