1k of any bullet is gonna be heavy, so, shipping charges are always of interest. and, how far your point to point is. pays to shop around.
i use Oregon Trail Laser Cast. they are in Oregon and i am in Arkansas. i ordered a bunch last year and at that time, the price quoted included shipping.
i could shop around and save a little i suppose, but, these bullets are tops in my guns and not that much more. near eliminated leading of the bbls. i shoot my magnums hot so this is a blessing.
absolutely the cheapest way to go is cast your own out of wheelweights. have shot many thousands of these and they work as good as anything. bullet casting is an easily attainable art and an enjoyable one. recommend the Lyman manual on cast bullets and loads.
