Can anyone tell me why my hw80 in .22 shoots crossman priemier hps 14.36 grain
into 1/4' at 15 yards but when i shoot at 30 yards with an 8 kms headwind they open
up to 1.25" and shoot 1.5" to the left,i cant belive with 1/4" at 15 they would do this
at 30.I have tryed all differant holds etc and they do the same thing? think my next
move will be jsb hades 15.86 gr they will also shoot into 3/8th" at 15 yards if i seat
them 0.080" into the boar as they dont fit snug when you just drop them in.Thanks

Are you hunting with the 80, just asking because of the ammo you’re trying.

Do you know how many fps it’s shooting at?

Have cleaned the barrel, have inspected the barrel for say any burrs, is the crown ok.

Try shooting jsb exact if you’re after accuracy, any hunting pellet won’t be as accurate as a domed pellet , how old is the gun, are you using a scope.

Could be by 30 yards, those pellets are starting to gyrate around the point of aim, whereas at 1/2 that range, they are flying true.
At the higher velocities, I have not found Crossman Premiers to shoot well - at all.

That is what I'm thinking as well, I recall seeing a slo-mo video of a pellet in flight and it went straight and smooth then at some point went unstable, spiraled and wobbled, when the drag/turbulence reached a critical point. I had a cheap non-PAL break barrel a QB18, I could see the pellet spiraling along its trajectory through the scope. In the current cae though maybe there is more wind at 30 m than the OP realizes.

True - the wind REALLY effects pellets, much more so than "one" would think.
As well, wind nearest the muzzle has much more profound effects than wind downrange.
A small deviation close in, is magnified with range.

BR shooters always start flags in close. When using flags on our outdoor rifle range (200 meters) I
have observed 5 different wind directions (different on every flag) from 5 yards, out to 95 yards.

Yes I’m useing the .22 hw for hunting the crossman are going average 775 fps they flew 812 fps when gun was new.I have a new hawke airmax scope on the rifle as well. Barrel clean and no lead or burs.The crown is perfect as well I will try the Jsb hades in 15.66 gr they fly about 715 fps average.Thanks everyone

Forgot to mention the gun was bought mid winter and has about 600 shots through it now

Ok so the gun should have settled by now fps wise, I really think it’s the pellets, the hades are very good but just to see how accurate the gun is get yourself some jsb exact those will tell you how accurate it is at longer distances.

Good luck and let us know if it works out.

Thanks hw777 What weight should i try would the exacts in 15.66 grain be ok the
Hw hunter extremes in 18.66 grain are also 1/4" at 15 yards but very slow at
only average of 612 fps at muzzel

That's quite a drop-off in vel. and FPE on the 18.66gr.
Yes, by all means try the 15.89gr. Hades.

Try both…..since you’re hunting with the gun shot placement is #1 of course velocity matters too.
I get why you want to use those pellets (hades & hollow point) but if the gun shoots great at 30-50yrd with domed pellets than I’d rather use those knowing that the shot will hit where you’re aiming.

Some responses point in the right direction.

If the effects of wind can be disregarded for the moment, there are two basic factors that will cause excessive non-linear accuracy with ammo such as lead pellets. Non-linear accuracy essentially means that when distance is doubled, group size more than doubles.

One of them is muzzle velocity variation. There is no reason to think that between 15 and 30 yards it's the culprit as the MV variation to increase group size by a factor of 6 would be quite considerable.

That leaves the second factor and that's the ammo in question. At 15 yards most pellets should produce very small groups.

The cause of non linear group size variation is when the center of gravity offset between pellets varies. In other words, the center of gravity is inconsistent from one pellet to the next. When the Cg offset is greater, the group sizes are themselves greater.

Crosman Premier pellets available by the tin are relatively poorly made pellets and are more likely to have Cg offsets that vary considerably. Better quality pellets such as JSB or H&N may have more consistent and less significant Cg offset variation.

Center of gravity offset issues are unavoidable in soft lead projectiles such as pellets, .22LR ammo, and lead bullets used in firearms such as black powder guns. To illustrate, even when MV variation is taken into account, .22LR always performs worse as distance increases. If someone can shoot 1 MOA (about .5") at 50, he should expect results greater than 1 MOA at 100.

The best solution for FlyFisherMan is to get better quality pellets.

My 2 cents / you have to test different pellets, was having a heck of a problem using one type of pellet in my HW95 , just happenned to have a can of some pellets that I wasn"t crazy about in my kit and tried them and got exceptional results.

Thankyou everyone for all your help and your suggestions i will be sure to look into all of them.Cant find any jsb exact 15.69 grain any place in canada seems like everyone is sold out.Will do more work with the hades 15.69 grain and the hn barracuda extreme hunters in 18.69 grain as i have these on hand i have 500 hades and 500 hn barracuda hunter extremes they all shoot well out to 20 yards so will see how they shoot at 30.Problem is here in central sask canada we have so much wind even in morning at 6am there is 2-5 mph winds this time of year and they change direction so fast.Thanks again.

I use the Hades because they are the MOST ACCURATE in a couple of my rifles. If it shot better with RN's, that is what I would use.
