Is it good practive to use a rangefinder that corrects for elevation differnce between the shooter and the target?
Seems that if you have a rangefinder, this is much more precise ...at long distances... than using holdover or some sort of BDC reticle.
There are a lot of assumptions going on here but if you have spent time behind the rifle, if you have valid field data that produced your range card, if there is no wind and if you know the exact range via your rangefinder, then "theoretically" it is just dial and shoot. But, there are a lot more things involved.
One of the best things I could tell anyone that has even the slightest question about long range shooting would be to invest in Shawn's long range video. It will answer all of your questions and tell you things you may never have thought of. Link--> Long Range Hunting-Video (Shawn Carlock, Defensive Edge)
I personally don't use an angle/range indicating range finder. I use a Swarovski and love it. The problem with angle shooting is that the distance via the angle/cosine method or however you come up with the "real" flat land distance, is that you actually need to put the lazered distance and angle into a reliable ballistics program if the range is very long at all. The difference, especially at longer ranges, can be more than you would think.
Even though I use a rangefinder I also have a reticle that allows me to range an animal if needed. Having said that, I still laser everything and never "guess" at a range using the reticle. Animals body sizes vary to much and for me it would be just like guessing to range an animal at long range with a reticle.
I also know that a lot of people say if you have an electronic piece of equipment that it will eventually fail so the reticle may get used some day but not unless I have to and then I'd limit the range. I carry spare batteries for all of my electronic equipment when shooting/hunting so battery failure is only a temporary problem at most.
Highly recommended are the best range finder you can afford, a reliable angle/cosine indicator
, a good weather meter
and a good external ballistics program in a Pocket PC or Palm that you carry with you in the field as well as your proven data/range card.
