Guest tanks Posted December 30, 2013 Share #1 Posted December 30, 2013 Advertisement (gone after registration) Santa had a gift for me waiting under the tree a Leica 1600-B Rangemaster. Leica Camera AG - Sport Optics - Rangemaster Last weekend I was able to test it out in the desert. Put a target a ways off. The Rangemaster estimated the target to be 747 metres. I plugged in the numbers into my ballistic calculator (iSnipe) for the iPhone, and made the MOA adjustments on the scope. Every shot was in the black (shooting prone). Now, the Rangemaster also has ballistic curves built in where it tells me the adjustments I need to make in MOA based on the distance the rifle was zeroed, ballistics of the cartridge etc., etc.. I have to figure out the exact inputs for that as the manual is lacking as usual. Though most probably will keep on using iSnipe as it is a very through and flexible app. Overall, I was impressed with the product. I'd recommend it to anyone needing a range finder. The only negative nitpicky thing I'd say is that it requires a CR2 battery, so will have to buy some spares. Link to post Share on other sites More sharing options...

stuny Posted December 31, 2013 Share #2 Posted December 31, 2013 Does the ap allow for windage? Link to post Share on other sites More sharing options...
luigi bertolotti Posted December 31, 2013 Share #3 Posted December 31, 2013 Yes, it seems... not an expert on the matter, but always fun to discover such little marvels (in the first '80s I experienced, in the Army, the fabolous ANALOG VALVES BALLISTIC COMPUTER for antiaircraft artillery... over 100Kg of Electronics of the '60s... ) "Using the exclusive Direkon Ballistics Library, iSnipe™ generates military grade 3-DOF solutions for small arms trajectories, including corrections for Pitch, Yaw, Wind, Coriolis/Eötvös Effect, Spin Drift and Atmospheric Conditions."

Guest tanks Posted December 31, 2013 Share #4 Posted December 31, 2013 Does the ap allow for windage? Yes. It does. It can also measure angles up or down, but so can the Leica rangefinder. The app also, based, on the GPS co-ordinates can get the environmental information (assuming it has a signal). The Leica also has a temperature sensor as well. So, covered both ways.

luigi bertolotti Posted December 31, 2013 Share #5 Posted December 31, 2013 Btw... the iSnipe description seems to me even a bit exaggerate... really on "small arm traiectories" the Coriolis effect can be numerically appreciable ? Link to post Share on other sites More sharing options...

Guest tanks Posted January 7, 2014 Share #7 Posted January 7, 2014 Advertisement (gone after registration) Btw... the iSnipe description seems to me even a bit exaggerate... really on "small arm traiectories" the Coriolis effect can be numerically appreciable ? I am not sure it is or not. However, all the ballistic calculator software that I have tried have mentioned compensating for it. In most cases ballistic calculators are used to help developing loads, and gross adjustments rather than the final word. In the Marines we used to use ballistic tables already printed, my spotter would tell me how many clicks I'd have to adjust the scope in order to hit my target. For example, I will be hunting Elk in Wyoming starting October 15th 2014. I will need to develop a load for a 250 grain bullet as the shots there will be over 300 yards, and the 300 grain bullet I use for African game is not as flat shooting. The ballistic calculator helps me play around with parameters in coming up with the velocity needed for the trajectory I want, while still keeping chamber pressures within safety margins. Then, I work out a load and experiment until I get the most accurate, fastest load within safety parameters. Luckily, in the US we can reload our own ammo and experiment with various combinations. 2 Link to post Share on other sites More sharing options...
wattsy Posted January 7, 2014 Share #8 Posted January 7, 2014 It all sounds a bit geeky to me. Whatever happened to shooting as a sporting activity? For example, I will be hunting Elk in Wyoming starting October 15th 2014. I will need to develop a load for a 250 grain bullet as the shots there will be over 300 yards Have you ever considered using a bit of fieldcraft skill and knowledge to get closer?

almoore Posted January 7, 2014 Share #9 Posted January 7, 2014 I will be hunting Elk in Wyoming starting October 15th 2014. I will need to develop a load for a 250 grain bullet as the shots there will be over 300 yards, and the 300 grain bullet I use for African game... This is all so last century. When I want to terminate a moose, chipmunk or elephant I simply call in a predator drone from the comfort of my own home. It's like the switch from film to digital - I could never go back to the fuss of the old days. Embrace the future... 1 Link to post Share on other sites More sharing options...
Guest tanks Posted January 7, 2014 Share #10 Posted January 7, 2014 (edited) It all sounds a bit geeky to me. Whatever happened to shooting as a sporting activity? Have you ever considered using a bit of fieldcraft skill and knowledge to get closer? Well, considering you start at dawn on horses in trying to find the Elk, I'd say it is sporting enough. There is plenty of walking and stalking as well to get within that shooting range (Elk can sense movement within half a mile). Anyone who thinks one can just pick up a rifle and shoot effectively at 300+ yards in the field has not shot outside of a bench at the range or not at all. That particular terrain does not lend itself to close stalking. There are other areas in Wyoming where one can do what you are suggesting. I drew my license for a different area. By the way my chances of finding the Elk is less than the other areas where the Elk are a lot more approachable due to the terrain. I expect my hunt to be very similar to the one outlined in the story below, except Elk instead of mountain goat. That should give you an idea. http://huntforever.wordpress.com/2013/12/27/sparks/ Edited January 7, 2014 by tanks Link to post Share on other sites More sharing options...

Actually, it seems it does make a MOA difference between shooting east vs west. So, if one is shooting 1,000 yards point of impact moves 10 inches or so between the two directions.
