Little Crow Gunworks has an new Video on you tube. Good stuff, very interesting and informative, especially for the big 7 lovers and not so big 7s. Gives great insight and proof of the importance/influence of barrel time during load development. For those like me that like to nerd out on well thought out testing this is a great video. For those that don't., you can still get an understanding of what is happening with your groups. For those of you that are challenged it will fire you up to defend the hornady marketing machine. Something for everyone. Enjoy and thank you for your effort hard work and sharing little crow.
