Just want to share my experience wasting a lot of time tying to find another source for springs for TylerR's awesome bullet feeder dies. After a long Google search 3 times I finally found springs at McMaster-Carr that may work nearly as good as the ones I bought in the assortment pack for $11. You can order them in packs of 12 for about $12.....but then you have to pay shipping and tax for another $10.....so $22 for a measly dozen springs. https://www.mcmaster.com/9654K957/ Forget that.
The Chinese spring Assortment, which I bought for $11 has 10 springs of the right size which is shown in my pictures of my finished dies. Amazon no shipping. But you have a large # of other springs to store and maybe never use of course. I did find that assortment at another amazon store for a little cheaper so I ordered that one too for extras. So I'm springed for life I think.
Plus I think the round ends on the Chinese ones, being really just a flipped coil on each end allows for a neater closer, more professional look. I've got three built using 6 springs.....so I can now build 7 more as needed for other calibers of pistol and rifle. For me, should be enough.

The springs I use is the extension springs in the top left corner of the assortment. Crazy to have to buy all those springs....but it's the cheapest way I can find...and they fit like a glove.
