[QUOTE="Guest, post: 37213"] [b]Thoughts on BDC\'s[/b] Since this sorta was a controversial topic I thought I'd share my thoughts and some realities of this is it applies to the LR hunting aspect. I feel some of the information prior to this was misleading. There a numerous people here who are interested in learnin and aquiring information so I thought I'd share my ideas and information on BDC's The pros easy "doping" if you know your rifles performance. Simplicity in the field for the inexperienced. Possibly a good tool for the novice. cons... while in reality they appear to do what they are intended for it really could cause problems. These BDC's are made for a rifles spacific performance with a specific bullet, specific powder, specific primer. That in itself spawns numerous problems. I can show drop charts with varying conditions that will show impacts with enough variation to cause a miss or wounded animal. Based on atmospheric conditions alone. But consider these variables as well. Your perfect powder,primer,bullet combo works really well in your back yard. But you travel to a different elevation or climate to hunt. well your powder perfromance may not be the same in your hunting area... maybe you have an enormous pressure increase or decrease... now what? Couple that with the bullet performance at a the changed altitude, and atmosphereic conditions... you have a recipe for disaster.
