heavier the pellet

[Deker 3,478]

Happy New Year......everyone knows this pellet business do they...so where is the science...not a shred of evidence and I suspect none of you have the facilities to scientifically test this!! Neither do I. I cannot measure or check my barrels or pellets that accurately!

 

Guys

 

I don't care what you want to believe ...when I see the evidence I will accept it...if you want to believe what you heard from a million people I don't care, but seems more than a bit strange to me that apparently everyone knows it and NODOBY is able to point me in the direction of any science!!

i have a rapid mk1..

 

i use bisley LRG " long range gold " & i always set the ftlb to 11.5 approx, but when i put a heavier pellet through it, the ftlb drops considerably..

 

i also tried setting the ftlb at 11.5 with bisley magnums, as soon as i put the LRG`s through the ftlb rocketed..

 

i personally think each rifle is different..

well have you tried it yet then deker and what were the results ? you are asking hunters the scientific answer lol , play the game fella and stop with asking for science and try it yourself .

like i said i dont know why it does it but i have always found it the case.

[richie 1]

just done a test on my mk1 .22 rapid pcp....

 

chronoed in with bisley LRG 14gr = 11.86ftlb

 

3 different pellet weights tested:

 

bisley superfields 14.74 gr = 11.25ftlb

 

bisley pest control 18.18 gr = 9.30ftlb

 

bisley magnums 19.66 gr = 8.19ftlb

 

i find the heavier the pellet, the ftlb decreases...

well care to explain why it goes up in a stealth all very twilight zone

strange, but as i say, my personal view is that every rifle is different, but have to say that i use to own a webley FX2000 & had the same results...

That will be the difference chap...just trying two guns is not scientific...did you measure the barrel diameter of the guns, did you measure the barrel length...did you check all the seals, did you measure the thickness of the lead deposits inside the barrels...did you measure and weigh all the pellets... what chrono did you use...did each pellet have the same clearance, were they all the same shape, what was the wind direction, etc, etc..it's called repeatable....not, my mate tried it in the garden!!

 

Chap...... that is the whole point NODOBY has done anything scientific here......I cannot get any result worth talking about by trying 2 guns with different pellets, Neither I suspect can anyone here...it does not matter if I try it and my results agree or dissagree with these suggestions ..it is NOT scientific and means nothing!!

 

I have been around a long while and I really don't care what you all want to believe..this one is very simple...some people heard a story somewhere and they are now trying to convince the world it is true. Well...as I keep saying I am not convinced, and until I see some Scientific evidence I remain unconvinced.....and how come NODOBY in the entire megasphere of the WEB hasn't come up with some evidence better than, my mate tried it in his back garden???

 

I started a thread shortly after this one asking for information and evidence on this subject...NONE was forthcoming, are you surprised I remain unconvinced...I ask again...ANYONE, ANYWHERE show me something scientific to back up these comments!!

i dont want to come across as though im starting an argument here, but havent you come across a pcp before that had an increase in ftlb the lighter the pellet ?

[chimp 299]

yeah yeah yeah deker the man who can light match's at 50 yards lol .

 

listen ,call me a liar if you want but what i do know i have a stealth here that is doing 25ft lb with magnums and and 17ft lb with field and target.

 

the chrony is an f1 . no i didnt do all that bollox you stated but thats what you get with a thick idiot like me .

 

deker you say you been round for a while is that why you are just stuck in your own ways now and believe you are something you are not ?

 

i know what i got with the guns i have available and have tested it myself , a gun tuner who has tested 100's of guns says the same but you must be right .

 

my chrony must be wrong lol

 

like i said i havent got a clue why my stealth and all other pcp's have come up with the same results

You are jumping to all sorts of conclusions for no apparent reason....I have NEVER said I am "right", or anybody else is wrong, these results make no sense, and until I see some evidence I am not convinced...that seems to cause you some sort of a problem....

If you care to look back I have not said anyone is liar, just that I am not convinved, and I fail to see what this has got to do with being a good shot..I have also made it very clear that you believe what you like, your chrono may well be spot on but if the pellets don't fit the barrel equally the results are meaningless...seems you are getting a little upset at not being able to produce any evidence, whats your problem if I am not convinced?

Best add my bit again to stir the s**t

All I said was that on testing a pcp using, say 16 grain pellets, and getting spot on 12 ft/lb, why, with no alterations to the rifle except pellet weight! why does the ft/lb increase to over 12ft/lb.

And why when getting say 11ft/lb with Magnums in a springer then changing to a lighter pellet does the ft/lb increase?

The initial 'observation' was posted to make people aware this can happen and therefore make your 'legal' air rifle over the limit purely by using different pellets!!

We are all aware Deker has FAC air rifles so is poss less worried by this strange phenomenon, most of us want to try to stay within the law!

And here to put the cat among the pigeons is my theory:-

 

The energy produced by your gun is a constant & the only variable is the feet per second velocity of the pellet, which in it's turn is determined by it's mass.

Higher mass = lower velocity for a given impetus of energy.

Therefore, it matters not whether your using a springer or a pcp, because the energy produced by either remains constant irrespective of the weight of the pellet, with the velocity being a derivative of how efficiently the gun expels that particular weight of pellet

You're approaching the maths from the wrong direction.

in english please ?

 

my theory, tested, & no, not under a scientific lab control but here goes, yes the air weapons power remains the same, give or take...

 

the heavier the pellet, the slower it leaves the barrel, the less ftlb is measured on a chroni..

[j davies 8]

On a PCP the heavier the pellet the greater the ft/lb

On a springer the lighter the pellet the greater the ft/lb

Always be aware that pellet weight can take you over the 12ft/lb limit!!

 

hi been reading what you been saying does the pellet tin tell you how heavy there are. i got an s400 what waight do pellets come in

all i know is i am not a scientist if you whont scientific evedence find a science forum this is a hunting forum for hunters not scietists. people on here tend to buy a gun find a pellet that it likes & go hunting with it. people on here are hunters not scientists so no mater what they say they dont use a lab have a deplomer on the subject so your not going to beleve them. so why have you asked them there apinion on this subject there just hunters after all they just go out & test there guns in fields & that is it. what if the wind was blowing down the barrel on there first shoot then to the side of the barrel the second shoot even if the pellet is the same. we are just hunters pissing in the wind talking to people like you its a waist of time when we dont owen a lad & have a science beplomer so why ask our apinion in the first place? if you whant a scientfic answer you will have to pay some scientist to do the test in a lab for you becouse all you have sead so fare is your not a scientist & you dont have a lab i dont beleave you. why ask
