BSA are you sure your Hawkeye has a 1-12? The Ruger website shows it with a 1-9.
You just made my day. I looked at the website and it looks like you are right. I was just going off of what the guy behind the counter told me when I bought it. I should of known better!!!! That's probably why it stabalizes the 64 gr. bullet so well. Great deer pics by the way too, shows you what the little .223 will do with the right bullet. Thanks for the info on the twist rate. Much appreciated, BSA.
