Evilv Posted April 1, 2017 Report Share Posted April 1, 2017 I found this good video about rabbit control with a FAC air rifle. Worth a look maybe... https://youtu.be/r41-1kh-3l8 Quote Link to comment Share on other sites More sharing options...
turbo33 Posted April 1, 2017 Report Share Posted April 1, 2017 Thanks for posting that, a well put together video. Quote Link to comment Share on other sites More sharing options...
jam1e Posted April 1, 2017 Report Share Posted April 1, 2017 Nice video that. I liked the way he used a long piece of ply wood to work out the pellet trajectory. I'll try that out with my Daystate Air Ranger. It's in .25 calibre running at approx 44 ft/lbs. I bought it a while back, but haven't used it much really until i needed some pigeon decoys the other week. I'd forgotten what a cracking gun they are. I'll be using the same technique with the plywood to in a few days time. Thanks for sharing. Quote Link to comment Share on other sites More sharing options...

I like the way it gives such a graphical demo of the trajectory. My problem is that shooting with the air rife, 22LR and 17HMR, I have to keep translating from one to the other. This calculator lets you work out where the flattest part of the ballistic curve for your particular gun is though and if you restrict yourself to those ranges, it is pretty much point and shoot. http://www.shooterscalculator.com/ballistic-trajectory-chart.php Enter your round's parameters and set the chart interval to 5 yards. You need to know bullet weight, ballistic coefficient and velocity. BC of many air gun pellets can be found here: http://www.photosbykev.com/wordpress/userfiles/pelletdata.htm And here too: http://www.chronoconnect.com/pellet-list.html This calculator is useful if you know the muzzle velocity with one weight of pellet and wonder how the gun will perform with a different one. You can use your power at the muzzle to estimate velocity with different weight pellets. http://www.pyramydair.com/airgun-resources/widgets/convert.php?Units&u=14 Of course, you can also just use the plywood board to work out where the flat part of the trajectory is Edited April 2, 2017 by Evilv Quote Link to comment Share on other sites More sharing options...

I do use a ballistic calculator, but i never knew you could get a pellet bc. Nice one! Quote Link to comment Share on other sites More sharing options...
