Air Rifle Pellets

Vegeta

Hey guys,

My Dad's .22 30ft/lb PCP air rifle is not grouping the best these days. I want to sort this out so the first port of call is to change pellets to a brand used before and that were accurate.

We used to use Crosman Accupell and they were laser accurate at 40 yards but Webley make these now I think and quality is gone down hill supposedly.

So can anyone recommend a premium, quality brand of pellets to try out?

This thing hasn't been serviced in years either so that could be the cause of it but I'll start at the cheap end, a tin of pellets. He's using Gamo at the minute and either they are not suited to the rifle or the regulator needs a service.

Thanks

What make is the gun? Some show a marked preference for one particular make and shape.

It's a BSA.

Yeah I would just go back to the Crosman (if I could find them here) but since Webley took over the on-line reviews seem poor. This makes me reluctant but I'd buy a tin to chance them.

I just called my local air-gun maven who instantly suggested RWS Superdome, Harrier Hustler or Harrier V2.

Be aware that air rifles over 12ft lbs are RARE here in UK - your results may therefore differ.

For premium, the ISSF manufacturers jump to mind - RWS and H&N and JSB all do pellets for hunting airguns as well as for ISSF airguns, and their manufacturing would be on the same level for both in terms of consistency.

But honestly, it sounds more like a servicing would fix the problem...

Vegeta

Thanks folks appreciate that.

I too think a service would go a long way but we're only too aware of the awkwardness of getting that done here

I have never liked the Gamo pellets he's using now so will try the cheaper alternative and source some of your recommendations first.

Know of any stores here which stock them? Long shot I imagine, double :(

Tiernans has RWS pellets; Intershoot has JSB and H&N.

Air arms do a real nice pellet for the precharged stuff it's seriously good in the s410 and also the s510.
The pre charged rifles need heavier pellets to operate properly I find.

That's handy to know - a recent poster with a Steyr might like to know that.

If you are looking in, John, you'll need the H & N Finale Match 4.50.

Yes - I suspect a service (or clean the barrell if needed). Also, for 30 foot pounds you need a heavier pellet - Bisley Magnums spring to mind, I cant remember the exact weight but the lighter pellets are only suitable for the 12 pounders.

Bisley Magnums are very good

flanum

would highly recommend Air Arms (Field).

demonloop

JSB also do a 'Heavy' version of their .22 pellet, aptly named JSB Heavy

They also do a monster weight version; called JSB Monster

Still waiting on my HW100 to come in, anyone know what pelleys they like?

i am no expert on air guns but it might just need to be serviced.

the main part being the regulator

if you remove the regulator and send it to this guy. http://www.johnbowkett.co.uk/

it may be just as simple as that

best of luck to you

Whoa! Don't try that one at home. A 30 ft/lb PCP rifle is going to be up around 200-300 bar of pressure at least, if you didn't remove and replace the regulator perfectly, things could get explosively nasty. And frankly, I'd much rather get shot with a .308 than have the compressed air in a PCP rifle go off in my face, at least you'd have a chance at surviving the .308. You've seen what happens when compressed air tanks let go?



That's from a 180bar dive tank. More energy than in an air rifle, but the air rifle would be up close to your face and the total energy released by the tank letting go would be equivalent to two hand grenades...

My Bsa loved Fx pellets. I got them in Nenagh in Open Season.

silly me spaks what would i know. i would of course unload my .308 before i clean it but maybe i have bin doing it wrong.
with that in mind i guess one would remove the the air tank before doing any cleaning or servicing
have a look at this video it will explain it all very simply for you.

as your pic shows above, pressurised air can be very dangerous, and so i would hope that anyone using dangerous air would not let their equipment fall into such disrepair as shown in your pictures

Paulo, that tank in my picture?
It looked fine before it went bang. It wasn't being filled at the time. It had up-to-date visual and hydroinspection tags, meaning it had been looked at inside and out professionally. And it went bang, demolished the shop it was in, going through a brick wall in the process.

Yeah, I'm going to be a wee bit cautious about compressed air cylinders mate, I'm just paranoid that way. I also wear seatbelts when driving even though I've never been in an accident and get travel insurance before going abroad even though flying is incredibly safe. I guess I'm just a big wuss

tac foley

Just like with a magazine-fed firearm -

Step 1 - remove the magazine, in this case, the air bottle.

Step 2 - safely and without a pellet, discharge the charge remaining [there may not be, but do it anyhow].

Carry on from there..................

good for you. better safe than sorry.

my advise still stands though. did you watch the video?

if you dont want to remove the regulator your self you can send the entire rifle to the man him self, but then you have to deal with import and export red tape etc. or maybe there is someone in ireland that can do the job for you.

i am only trying to help. and from the sound of what vegeta said this could be the problem.

if you want to start having a go at me then please continue, i wont be replying to you unless you have something intelligent to add.

Unfortunately it's not a Super10 my Dad has but if it was I would definitely follow the youtube video you linked to. Very clever design on that rifle.

Oh and it's alright lads we use a foot pump to fill it. Heart would be thumping from it but it's a cheap way of doing it.

Another vote for the JSB Exact Heavies - particularly at that power level.

I use them with a 16ft.lb .177 (10.4grn) straight from the tin and in the absence of a crosswind they're good for 70m on a 40mm spinner every time.

Imagine that despite the extra weight of the .22 pellet, with the additional power that Scorpion (I assume since it's a BSA PCP) is pushing, you should expect pretty similar ballistics too (0@25;-1@45;-2@60;-2.5@70 for my machine).

Vegeta

My first port of call will be nagging a lad in work for a lend of a chronograph. If the fps deviation is not too bad i'll try and get some JSB pellets.

Thanks guys

Vegeta

So chronographed the air rifle yesterday and there was nearly 100 fps spread. Not good enough and regulator it is.

Any Air Rifle folk know where I could get this serviced?

why dont you contact the lad i gave you the link for. he was involved in designing other air rifles as well, not just the super 10.

at least you will be talking to someone who knows what he is talking about.

is the regulator all that different to the super 10. i am sure you could have it removed and sent on to the man with out any problem.
there must be some one out there that has a similar rifle that has done it before.. i fairness once the air tank is out of the way its just a few nuts and bolts

The main problem I have is that JB is in a different country and has up to 6 month waiting list. I would much rather get it sorted by someone I could bring the rifle to and collect it from. Failing that option I will contact John but I will definitely at least try local first.

I imagine the regulator is not that different but looking at a blown up diagram of the rifles the strip procedure is different and I am currently looking for forum access on the BSA forums to see how it is done.

There is a guy sorting the issue here:

May give it a go myself with a bit more research

As a matter of interest, what pellets were you using?

It's not uncommon in cheaper pellets to find variance in both the head width and the weight between pellets, casting dust and swarf can also cause variations.

JSB's and RWS for example (high end pellets) are, in some ranges available in specific head widths (4.51 & 4.52 most notably for .177) and that difference in the head width does impact significantly on the muzzle velocity.

I'm not saying that it's not the regulator that's at fault - just that it'd be no harm to clean, measure and weigh a series of pellets before chronographing in order to eliminate as many variables as possible.

They're some form of Gamo pellet, expanders or something.

yyeeesh - dude, that could potentially be the entire problem right there.

GAMO are readily available in most RFD's here, but unfortunately, they're complete ****e.
