asap Posted July 17, 2009 Report Share Posted July 17, 2009 please dont reply telling me how to shoot safely as i already know . What i was wondering was if you fired a rimfire using subs from shoulder height in a straight line,how far would it travel before hitting the ground, the same question for shooting 45 degrees in the air . Also if you fire it straight up in the air how long before it came back down ,how far away from where you had the shot would it land and how fast would it be going on the way back down. Probably no one knows but i was just curious :( Quote Link to comment Share on other sites More sharing options...
Beardo Posted July 17, 2009 Report Share Posted July 17, 2009 (edited) this is very rough.... .22lr sub fired from a 6ft tall person standing - 225 yards til it falls 65 inches with a terminal energy of 1.377 ft/lb not sure on the 45 degrees though Edited July 17, 2009 by nickbeardo Quote Link to comment Share on other sites More sharing options...
asap Posted July 17, 2009 Author Report Share Posted July 17, 2009 Cheers nick thats handy i thought it was more :( Quote Link to comment Share on other sites More sharing options...
ryantidgwell Posted July 17, 2009 Report Share Posted July 17, 2009 as for the straigh up and straight down bit on the way down it would only be going 60 mph or there abouts , thats about the terminal velocity of a bullet coming down , Quote Link to comment Share on other sites More sharing options...
Beardo Posted July 17, 2009 Report Share Posted July 17, 2009 so a 40grain .22lr round at 60mph will only have an energy of 0.68769 ft.lb Quote Link to comment Share on other sites More sharing options...
ryantidgwell Posted July 17, 2009 Report Share Posted July 17, 2009 yea would prob just bounce of your head if it was fired straigh up , Quote Link to comment Share on other sites More sharing options...
Beardo Posted July 17, 2009 Report Share Posted July 17, 2009 (edited) i dare say it might hurt a bit. can i also add - i really would not recommend firing any rifle into the air! Edited July 17, 2009 by nickbeardo Quote Link to comment Share on other sites More sharing options...
ryantidgwell Posted July 17, 2009 Report Share Posted July 17, 2009 would not have thought so , Mythbusters tested this and no way will it be coming fast enough to even break the skin , Quote Link to comment Share on other sites More sharing options...
ST3V3 Posted July 17, 2009 Report Share Posted July 17, 2009 (edited) maximum range 663 yrds optimum angle is 21 degrees energy will be 2.133lbft when it hits the floor with a muzzle velocity of 1085 ft/s Edited July 17, 2009 by ST3V3 Quote Link to comment Share on other sites More sharing options...
henry d Posted July 17, 2009 Report Share Posted July 17, 2009 .......

Bazooka Joe Posted July 17, 2009 Report Share Posted July 17, 2009 maximum range 663 yrds optimum angle is 21 degrees energy will be 2.133lbft when it hits the floor with a muzzle velocity of 1085 ft/s Wonder why it's got 1-1/2 mile on the box then ?

njc110381 Posted July 18, 2009 Report Share Posted July 18, 2009 Hobbits range sounds more reasonable to me. A .22rf will do far more than 663 yards. I often wondered whether it would be safe to fire a HMR in the air. Don't all jump on my back here as I never have, but with only 17grns of bullet the terminal velocity isn't going to give it much energy on its return? A .22 air rifle carries more weight than that! I know it goes slower but when running on gravity I'd imagine it travels at about the same speed? Quote Link to comment Share on other sites More sharing options...

I know it goes slower but when running on gravity I'd imagine it travels at about the same speed? I take it when you say an air rifle pellet has more energy, you're referring to when it falls from rest to terminal velocity? The problem is that a bullet fired skywards at even a few degrees off vertical will still follow a parabola. So not all the initial energy will dissipate due to the horizontal components of velocity. Not to mention the effects of lateral winds and air currents. long story short, dont shoot rifles into the air.... shot shot Quote Link to comment Share on other sites More sharing options...

Tiff-TRG Posted July 19, 2009 Report Share Posted July 19, 2009 Not sure on the max theoretical range (outside of a vacuum...), but I've shot .22LR rounds out to 500/600 yards before on steel sheets. I'll have a look through my video tapes and if I can find it again will post it up . Forget about holding MOA or MIL's it's like holding off consecutive telegraph poles! If I've lost the tape, I'll do a re-run the next time we get some settled weather....so probably next year at this rate! Quote Link to comment Share on other sites More sharing options...

stevethevanman Posted July 20, 2009 Report Share Posted July 20, 2009 (edited) On a box of .22LR subs, doesant it say something about how far dangerous they are? Steve Edited July 20, 2009 by stevethevanman Quote Link to comment Share on other sites More sharing options...
notsosureshot Posted July 20, 2009 Report Share Posted July 20, 2009 On flat land you would want visibility of at least 1 mile if shooting .22lr. However, this is purely theoretical since you're shooting into a suitable back stop right? Quote Link to comment Share on other sites More sharing options...
casts_by_fly Posted July 20, 2009 Report Share Posted July 20, 2009 On a box of .22LR subs, doesant it say something about how far dangerous they are? Steve Steve, Yes, most boxes of 22 LR ammo say dangerous to a mile or mile and a half. However, from any ballistics calculator you can calculate just how far it is physically possible for the bullet to travel. 3/4 of a mile is about the realistic maximum. If you had a heavy tailwind then you might be able to hit a mile. The dangerous to 1 km is about perfect for being realistic.
