my biggest problem is that these are marketed to people who do not understand ballistics. for example they buy a turret marked for the elevation were they live lets say 2000 then go into the mountains to hunt at 6000 ft they then use there range finder and miss completely or worse yet wound an animal. there is no simple "just dial" solution as these new turrets would have the uninformed believe. I feel its best to leave them to minutes and mills so people need to learn the whys and what fors instead of a quick fix that doesn't really fix anythinggun)
400 is jacked if you set your gun up right your 0 will be around 300. go out to 800 900 or even 1000 like some of these guys are using on their advertising and the difference in not so small, infact very large, add in all the other elements and these new turrets are a formula for giving long range hunting a bad nameI think if you run those number's you'll find the difference is very small and not enough to make a hunter miss a deer at 400 yard's, wind not considered.
No matter what, time behind the gun is important as is an understanding of your rifle's ballistic's if you want to be a successful hunter.
I've seen far more new guys jack up inputs into a ballistics program than have issues with a BDC dial, you have to go through some involved steps to get your turret set up so it's not like you just roll into a store and pull one of the shelf.
ha ha yah the same ones using the and thinking bdc turrets are a good idea! The reason ballistics programs are so complex is because LONGRANGE SHOOTING IS SO COMPLEX bdc turrets and reticals are no substitution for math and knowledge as they are being advertised (and I quote" Simply turn the dial to 800 yrds and boom'elk falls'.. dead on!") very irresponsible advertising!gun)
