I forgot about a 10 lb. 500 nitro single shot ruger #1. I have run max loads of 570 grain bullets out to 2365 ft./sec for a hair over 7000 ft. lbs, it is a pretty good thumper. I have not been shooting in a couple of months since my boys accident. But I hope to start shooting again in several weeks. It is just hard since Kyle was my shooting buddy for the past 10 years.
