Drop me your address by P.M mr Ditchman and il send you a sample of H n N,and some R.W.S and some Interceptors theyre all around 15 to 16 gr weight but your rifle will tell you whats best atb
that is a very kind offer...which i would love to take up...as i am rapidly becoming a "lead mountain"..
trouble is im shooting a .177cal.....

My Supersport loves H and N field target trophy ,and if i use cheapo spitfires they spin .. I know as the pellet hole is the side view of said pellet where its spun through .If you buy a selection pack some pellets are pushed in as theyre tight = H and N ,R.W.S and Bisley Magnum,but spitfires ,coppapell and Lanes drop in very loose .
Trial n error Ditchman ,your piston will bed in over time.Buy 2 or 3 selection packs and enjoy bladdering potatoes ,cardboard boxes ,and paper targets till you find 1,s your rifle likes .
The more you trial the easier your piston will be and it beats T.V any day atb
looking on various forums......more and more the brand comes up of H&N....so i will have a go at them....

any famous owners...like chris packham....hitler.....mousey tung...

The even darker art of O ring fettling is just around the corner
. I would try a selection of different rings from various sources as variables in inside dia and the flexibility of the materiel used in manufacture can make a difference i.e. an O ring id should be smaller than the od of the groove into which it locates - the amount of difference will effect the od of the O ring or, put more simply, the tighter the O ring grips the bottom of the groove, the smaller the od will be. Next comes the composition as various mixtures used during manufacture enable the O ring to exhibit different flexibility during use, obviously the more resistant to flexing the O ring is, the more pressure it will exert on it's component part. Just buy a bloomin PCP and be done with it .jesus getta outa here....you will do ma ead in ..
these "o" rings i am using are from Knibb's/chambers for the model "S".....i have 4 boxes of o rings ...metric imperial...and a sey of cat o rings which i wont use as they are rolled and not mold injected...........
really need someone to recommend me a pellet that will fit this barrel ..................
-
ive had it apart again.........sanded down the o ring........will try it out when the weather lifts...

Wouldn't be happy with Boris Island.
errrr....im starting to lose the plot here...

No, you don,t !
Plus the young, who he bribed with a promise to stop tuition fees, and the dossers, who think he will increase benefits!
No, he is not! It,s the young Marxists on his Momentum team who are good at PR for the young (and totally befuddled)!
Keep your licence up to date!
Beevis is a socialist!

Im surprised glastonbury are evem entertaining this idea... Itsca music festival, not a propaganda stage.. Im disappointed if this is actually happening.
well thats my idea as well......surprised the Beevis's have allowed this.........
-
Neither can I..first I'd clean the barrel & look for crown damage, leave the mod off if it has one to test it.
If that didn't sort it I would try a different pellet weight, lighter pellets traveling at higher velocities will corkscrew.
the barrell and crown are spot on......i now know the piston is too tight...so i will alter that first.............then try and sorce ANOTHER type of pellet...as the ones i have now i believe to be not a tight enough fit........
-
I seem to recall reading somewhere that the piston/seal should slide slowly down the cylinder under it's own weight?
if i modify it closer to your and figgy's post i should be on the right path ....as im seriously way out
-
Never looked at what weight is needed just felt for a nice smooth travel along its length with no tight or slack points.
thanks for replying...........i have nice smooth travel...but it seems very tight...need about 20lbs in weight to get it moving...the accuaracy at 12m is very good...5mm groups...but the groups blow at 25m...the gunsmith says the pellets are corkscrewing .!...(dont quite understand this) but he goes onto say...when he fits a new piston ring he will rub it down and keep fitting it in the chamber until he has a nice smooth travel...................which is what you were saying..........
but i cant see the relationship between the overtight piston and cork screwing.......but i can alter the "o" ring size but rubbing it down until i get smooth travel..
its just a suck it and see exercise .............the is a lot of thought and maths that goes into tuning ...and i dont understand most of it ...only the principles..

during the ID parade several old ladys fainted..

pray tell
no i musnt..............i took part in a post a while ago which explained the matter...........

He loves fiddling with them injector things
have you been awarded antique status on yer truck yet ?

you were about to have another stroke and grace pushed your hand away....

im still doing injectors............
.........but NO MORE ROOF VENTS PLEASE -
What weight is needed to start a piston with a new lubed "o"ring..on its travel down the compression part of the bore...before the gun is assembled

Helecopters can't go into fires. OK I can see that, drones start at a few hundred and are flown remotely. This is the deal, fry and die or take a chance on this big drone?
im sorry , i was just getting in the spirit of things and a bit of "black humour" wafted over me..........
please take no notice of me...
