Manufacturers and reviewers spec listing for airguns

[bchannell]

I wish we could get to some standard spec listing of velocity and shot counts, etc on reviews and manufacturer's specs. Something like what bow manufacturers do, they use a standard arrow with something like 4" vinyl vanes weighing so many grains, etc and you can then extrapolate velocity for your setup.
It would be something mid range like in .177 it would be a JSB 8.44 gr for everything not intended for 10M, for 10M it would be something like RWS 7.2 gr or whatever. For .22 it would be something like JSB 15.89gr or even 18.1gr.
The shot count should also be conservative and based on the standard pellet. I mean what good is it to list an extremely large shot count knowing full well. that when the consumer gets the gun, he will not get anything like that kind of consistent shot count. We're going to know in the end anyway. I don't think it's too much to ask for manufacturers to sit down and actually shoot each series' rifle and get an accurate spec.

I know they can list fpe and we can calculate velocity, but we all know, heavier pellets make more fpe, so that's not too accurate for any given situation. I wish reviewers would also go this route. I commend HAM for using a series of pellets listing velocities, and then we have an excellent idea of what we're getting and also doing a full shot string. That is the way it should be done.

They should also tell you what shoots well in their gun so you don't break the bank buying everything just to find out that most of it is awful in their gun.

We already know that! Crosmans shoot Crosman pellets best, Daisys love Daisys, Umarexs love Umarexs, Hatsans love Hatsans, Gamos love Gamos, etc.

Awesome, Good luck with that.

Really?

The only verified info I'm aware of is that the FX Royales' barrels were tweaked by FX for JSB pellets.
And boy did they do a good job!
Does any other gun manufacturer do that or something similar also?

I dont think it would be abad idea to have some standard testing but then again I always thought we should hae a standardized battery?

Air Arms comes to mind? Was sad when my beautiful new AA guns (springer and a pcp) both turned up their pretty noses at my crosman pellets that I had. Both dine on Jsb/AA (made by JSB) pellets. H&N is good (sometimes real good) as well but not great. I prefer great There are some manufacturers that will throw out a recommendation for a starter pellet/slug and then the owner can go from there of course. FPS rules are 'easy' to figure out; once you learn that the well made guns will actually shoot faster than specified and the cheaper made (Gamo comes to mind) stuff will often shoot slower than spec. Neither technically lies but one tests with an average weight pellet that you will likely use, while the other the lightest made non lead projectile they could find for bragging rights. Consistency among them all would be nice for sure!

Lots of manuals lying around where the airgun manufacturer recommend their company's pellets/BBs. Since we don't read the manuals, we don't see them! It used to be worse years ago.

I know my Brk gun came with a (generic) sheet of rangemaster pellets fps specs. If I recall they had a light, med, and heavy weight pellet run through it. I've never seen them available for sale anywhere in Canada but like so many other pellet brands in pretty sure Jsb makes them as well and then Daystate/Brk recommends them for their guns.

 

[pan60]

a standardized pellet regardless of manufactor would suffice for getting a standard speck.

the issue I see is some guns are designed to shoot a heaver pellet or a slug so how can you standardize it?
just thinking out loud

 

[SILENT SQUIRREL]

IMO there is no incentive for manufacturers to engage in standardized testing of velocity.
In fact, it is likely that there would be a disincentive to do so.
Think for a moment how head-to-head comparison would offer buyers a clear choice for one gun over another, especially if velocity were their primary criteria.
Why would manufacturers want to give the competition that edge?

Of course, if some well-endowed ($$) non-profit were to do the testing, that would be a different matter.
However, such a scenario does bring to mind the VW emissions scam from a few years ago
But then again
Air gun manufacturers are known to be among the most moral, honest.
And never play on emotions in their marketing.

Oh!
Where is Ralph Nader when you need him?

just my too sense

really id you think about it you need an independent inity to test, neutral and then you have some leval of confidence in the given data.
but again it woud be a challenge because not all guns are intended to be the same.
you cant compare a slug gun to a .17 pellet pusher.
national hard air magazine standardized testing.
what you have is the NHAMST

I agree to a point but if we went with say the Jsb 18.13 for .22 my S510 would be 885fps on max (at such and such temp/altitude). My Ghost @ max would be 1098fps. A springer pushing same pellet would be say 550ish fps. That would tell me right there to go heavier in the (25.39) and perhaps a lighter pellet (15.89) in the springer. A case can definitely be made for it!

thats why I said you cant compare a slug gun to a 17 cal
I dont think it fair to compare the S510 to your GHOST or my EVOL
you could set up clarification to solve this.
aside from the obvious pump gun to pump gun springer to springer you still cant lump all pcp in one catigory
you would have to decide on the algerithym you want to do this what that woud be I dont know with out some thought.

certinetly caliber would be a factor plenum six possibly or manufactures advertized intended use maybe?

it could be done

Keep in mind the majority of mass produced Airguns, at least PCP's are mass assembled to specs. A good distributor will test these products and inspect them before they get sold...some charge the consumer extra for this. Johnny might get one that's shooting an 18gr jsb at 900 and Billy might get one that's shooting at 870. They are adjusted within a close perimeter of specs, usually never exact. A few manufacturers for a fact simply don't test anything and plan for roughly 30% of products to be returned due to bad QC. Lol As far as reviews go I think it's difficult to pull something out of a box and immediately start reviewing it....I see this as an unfortunate trend of being in a hurry to get content out.
