I picked up a box of ammo and headed to the range yesterday. Got all set up to test fire the 788, and I realized I had bought 222 ammo, and not 22-250. Oops! The range is about a 25 minute drive, so my afternoon was wasted. Not sure when I can arrange to get back out to test fire it. I must admit, it was my mistake in picking up the ammo, but I was sure disappointed by not getting to try it out.
I don't even have anything that shoots 222.
