durbsguy Posted December 28, 2011 Report Share Posted December 28, 2011 Pellets are essentially lead shuttle cocks so are designed to have drag on the skirt for stability in flight so the MAIN issue is drag. I still think around 300 to 350 yards is the maximum. I'm not denying that drag exists I'm 90% sure of the formulas are correct before taking into account the drag. I don't know how to calculate the drag effect only calculated in a vacuumn Quote Link to comment Share on other sites More sharing options...
kent Posted December 28, 2011 Report Share Posted December 28, 2011 Shot size 7 will bounce off 1/4" ply at 50 yards, but still travels 300 yards. Yes it will go 300yds carried by wind etc (the range clay grounds use on set up) but i was reffering to another 300 yds plus, also air pellets tumble making them less efficient when destable than a round lead pellet. I have been hit by fives and sixes at 200 yds or so when picking up and you hear them more than feel them Quote Link to comment Share on other sites More sharing options...
HW682 Posted December 28, 2011 Report Share Posted December 28, 2011 (edited) Durbsguy I haven't worked through your calcs, but as you are using the standard SUVAT equations, I am sure you have got them right. However, as others have said, in this calculation drag is very important. It probably can't be modelled using simple algorithms. The point that kent is making if I understand it is that even most specialised ballistic software isn't particualry good over the full time of flight of an airgun pellet.

Yes correct, the maths cannot take into account tumble and near enough is a country mile out Quote Link to comment Share on other sites More sharing options...
jacksdad Posted December 28, 2011 Report Share Posted December 28, 2011 This needs sorting out! How about a Mythbusters style experiment, we need one gunner and about 500 volunteers to stand in a line under the trajectory, see who catches the pellet...simples I reckon about 600 yards, just my gut feeling!

Hamster Posted December 29, 2011 Report Share Posted December 29, 2011 (edited) This needs sorting out! I reckon about 600 yards, just my gut feeling! I've shot air guns since the age of nine and would get through one or two tins a week with open sights and everything off hand . People have mentioned tumbling of pellets in flight, , personally not convinced they do tumble even when they get much slower but in any case not convinced that would significantly reduce their terminal distance. If you put one in a catapult for instance, I bet it would travel well over 50 yards, with a starting velocity of next to nothing. Don't know about 600 yards but based on actual experience I would not put a penny on less than 250-300 yards.

richard1951 Posted January 28, 2012 Report Share Posted January 28, 2012 download hawke optics calculator , that seems to say a 12 in drop over 75 yds and it is dropping rapidly by then so it looks like just over 100 yds to me Quote Link to comment Share on other sites More sharing options...
jacksdad Posted January 29, 2012 Report Share Posted January 29, 2012 But that assumes you are holding the rifle more or less horizontal. Plus, for arguements sake, what if you were stood at the top of a cliff? :blink: Quote Link to comment Share on other sites More sharing options...

Dekers Posted January 29, 2012 Report Share Posted January 29, 2012 This thread has been around a while and I don't know, neither does anyone else it seems, and no program has been offered to show a viable answer. Who wants to organise a lot of members in the Spring/Summer to run some field trials? You will need a chronograph, lots of pellets (do a few calibres whilst you are at it) a big flat area, good eyes/optics and a long tape measure, then hope you are at Sea Level and it is a still day. Have fun and let me know the results. Quote Link to comment Share on other sites More sharing options...
jacksdad Posted January 29, 2012 Report Share Posted January 29, 2012 next to one of my perms is an old mill, the chimney top is 128 yards from me, rifle at about 45 degrees. I can hit it every time, I can see the pellet right up to it hitting, on a clear day So if/when I miss, how much farther will the .22 16gr pellet go? Its fields behind, so don't start telling me off!

turbo33 Posted January 29, 2012 Report Share Posted January 29, 2012 well if fire one straight up in the air it dont take long for it to come back down. so im guessing not very far. there only air rifles il volunteer to be a target and you can try and shoot me at 100, 150, 200 yards ect. il tell u if i feel it Think you might :yes: Quote Link to comment Share on other sites More sharing options...
brett1985 Posted January 29, 2012 Report Share Posted January 29, 2012 ive shot barn doors at a local farm at 250 paces with an fx cyclone in .177, no problems. there is guys in america that shoot cyclones out to 300 yards......... Quote Link to comment Share on other sites More sharing options...
jacksdad Posted January 29, 2012 Report Share Posted January 29, 2012 I've seen the woman with HW100 vid before, good! The pellets are going straight through steel cans at that range, so defo got a fair bit of energy left! Quote Link to comment Share on other sites More sharing options...
richard1951 Posted January 30, 2012 Report Share Posted January 30, 2012 yes and the dirt behind is kicking up .... im not convinced that that is not fixed. it is a few years from when i last had a air gun and that was a 12 lb one and i dont think it would have done that. i live on a marina and there is a lot more than 200 yds of warer there so when my new daystate comes in 3 weeks time i will try the water is still as a mirror and i can get someone to stand other end to see.

ChrisAsh Posted February 5, 2012 Report Share Posted February 5, 2012 (edited) For the olimpics the shotgun range had to be i think 300metre where as the normal maximum range is about 350 metre (max Range) using a 12 gauge shorgun with 28 gram cartridge and 7.5 size shot about 2.3mm diamiter This gives the round lead pellet a velocity of between 1400-1500m/sec depending on cartridge spec Therfore I find it hard to belive a non fac airgun could go further with a much lower velocity and higher drag pellet Edited February 5, 2012 by ChrisAsh Quote Link to comment Share on other sites More sharing options...

ladyjack Posted October 21, 2019 Report Share Posted October 21, 2019 (edited) I am going to put a8x4x1inch sheet of ply when I next shoot in a very long gullet on my perm,I will start at 200 yards and walk back in 50 yard increments, and see how far back I get before my pellets gets Lowe and lower,and finally misses the sheet,I will be shooting a FAC 28ftlb I'll let you know the final distance.,PS before anyone says it the ply will be against a big hill as a backstop Edited October 21, 2019 by ladyjack Spelling Quote Link to comment Share on other sites More sharing options...
figgy Posted October 21, 2019 Report Share Posted October 21, 2019 (edited) They don't tumble in flight even if not spinning, tafleadermouse fired a pellet shaped slug out of a shotgun and shows its stable in flight. It's why it's shuttlecock shaped. As for distance a calm smooth pond and watch for splash. Wind speed direction and atmosphere density will have a huge impact on distance.

Newbie to this Posted October 21, 2019 Report Share Posted October 21, 2019 Either way, I'm sure the flight time won't be 7 and a half years Quote Link to comment Share on other sites More sharing options...
