Re: range finders GG, brian b??
The biggest problem I see with long range rangefinders is the aiming point and here's why:
The farther you shoot, the more of an angle the bullet is coming down on regardless of what super hot rod flame throwing cannon you have. So, the range must be known to the nearest yard and it becomes more critical the farther out you shoot. If the aiming point in the rangefinder is say as large as 15 feet at 1000 yards, then it CAN NOT possibly range something that fits inside that aiming point to the exact yard. It will be close, but if it varies 15 feet than it varies 5 yards. That is not too critical at that range but lets say you go out to 1500. Now the aimer covers about 22 feet give or take a few. Your long range bomber is now coming down on a much sharper angle and the range may now have as much as 14 yards of error. On most guns at that range, it could be as far off as several minutes of angle. Not a big deal for varmints, but for trying to make a one shot kill on big game it is not good odds.
WHen you go out to 2000, it just gets exponentially worse because every ten yards causes the bullet to need 1 more minute of elevation (on the MOAG). So you can see how critical all this can get. THat is why the WILD and the rangefinder John Burns uses have such an advantage. THey have VERY precise aiming points that allow you to range exactly what you want to by aiming the unit exactly at your target. It is really like shooting at a paint can at 1000 yards with buckhorn sites compared to aiming at the same can with a 25x riflescope. /ubbthreads/images/graemlins/wink.gif
