They are still spendy, but not nearly as expensive as shooting vintage hulls. I bought a few recently and so far my 10 gauge loves them. I've been experimenting a bit, and have settled on 4 1/2 drams of FFFg and 1 1/2 oz of Bismuth. My full chokes will throw 76% and 78% at 40 yards with this load.

Something new to play with is always fun.
