I'm first time poster here and a long time watcher, most the info I need I find on your forum but I'm not finding a lot out there on how folks are using temperature sensitivity in their apps and how they are determining those values.
I have a question for the folks shooting more long distance with 22lr PRS style shooting. I have been playing with two ballistic calculators; Strelok Pro and Chairgun. I have a few questions I’m trying to figure out on temperature effects.
What temperature sensitivity range are you finding in SK and Eley and what value(s) for a temperature sensitivity factor (percent bullet speed will change at change temperature on 15 degrees Celsius)? Currently I’m using for SK ammos 2.6-4.8 and for Eley 1.6 to 1.8, which seems to be fine but I’m always tweaking at longer distances of 300M - I’m not sure if this is environmental or the prediction of my ballistic calculator. I fully understand the garbage in, garbage out theory and I’m trying to minimize this effect with temperature and how it plays into predicting accurate values at distance. So, my question is what Temperature Sensitivity Factors are you finding that works the best and do you always seem to have to tweak your ballistic data to make your bullet match the drag curve model frequently?
And lastly, do you use the Consider Powder Temperature on your app, or do you turn it off and if you leave it on? How do you consistently determine what the powder temperature is for your bullets when shooting or what value do you use?
Any thoughts would be greatly appreciated
