When we went we had 2 instructors. One guy was an older fellow maybe...late 70's and a CCWer and a great guy, Ex-Air Force and very knowledgeable. The other guy...well...aside from being a sexist and a bit of a half wit...well...he still was bad, lol.
They do their best at trying to keep your attention which was very nice. You are not just sitting there the whole time bored out of your skull. I can tell you more if you want to know it just shoot me a message. Also if you do get these two listen to the CCWer he was dead on when it comes to carrying and hunting. We had a ranger come in and correct the other guy, lol.
Back to the 223, one thing to remember about it is that
this round was designed not so much to kill but to wound. When the bullet enters it somersaults and very often fractures causing multiple wound channels.
Remember in military terms this is better because if you kill one person that is just one person out of the fight. If you wound someone then they are out and the opposing force needs to tend to him which means that another soldier or possible two will have to take care of him which takes more out of the combat situation. Also I use the term him in general, I do understand and acknowledge that there are many women soldiers in this day and age.
As for the 50, I thought you would blast apart the deer or elk to kingdom-come but if you check out this site...
http://www.50beowulf.com/bboard/forum.php there are some photos that are graphic in nature that show that the damage really is not bad. Much less than I thought it would be. Granted there are a few stories of much more damage...such as head shots which obviously would not be...pleasant but in the vital area really is not that bad. You figure there is little meat in the rib area anyway.
