When Henry gets back in September, Budget Shooter Supply is another source. I use Winchester brass in my IZH. Not promoting it, it's just what I happen to be using. Never had to double hit any.
For giggles, and only because I had the supplies on hand, I pulled the FMJ bullets and the corrosive primers. I replaced the bullets with 125 grain V-Max, and the non-corrosive berdan primers.
In spite of the sighting problems I was having the day I shot them, I was impressed with their performance.
