Hw95K .177 - Accuracy Issues

[Lamper121 239]

Hi All,

 

As you may see from my previous post I recently got an HW95k for my sons birthday. We initially got it zeroed at 30yrds with some not too bad groups and have taken a few rabbits with it over the last week or two.

 

However recently we had been missing some shots which were easy (and not just down to being poor shots!) and therefore decided to check the zero. When re-checking the zero we discovered it was off so we spent about an hour trying to zero it again. Eventually we got somewhere close but in general we notice the groups are not particularly tight at all ( maybe 2 1/2 inch) and sometimes the pellets go somewhere totally random.

 

Now we are by no means proficient air-gunners and I don't want to be the bad workman blaming his tools but is it harder to get tight groups with a springer than a PCP for example due to recoil? Or could it be that the factory standard HW95k is in need of tuning to get good close groups? Or do you think we just need to practice more!!?

 

P.S - we have been using the same tin of Bisley Magnums for all of our shooting so far therefore I've initially discounted change of pellet as a reason for the poor groups for now.

 

Any advice would be much appreciated!

give barrel a quick pull through maybe ? even though if its a new gun it shouldn't really need it - if it has a silencer on take it off and see if any difference - these are the 1st and easiest things to try mate -good luck -ftm

The stock bolts and scope mount bolts are also worth a check.

First off dont use bis mags in a springer there to heavy for them

 

Second ,,, iv had this issue with biz mags in my pcp.s there on one moment then off by a long way

 

and all ways the same spot on for a few weeks then off by a mile Vizlauk had the same issue with his bsa,r10 on then off a week later .

 

Plus if the rifle is new it will need a de,grease and re,grease with new grease

 

and clean the barrel out as well with a pull through while your on. New rifles are grease,d up with factory grease to protect them as no one knows how long they will sit in the rfd,s before they are sold .

 

hope this helps bud

 

and even if its not new i would do it any way

Thanks for the advice so far

 

@ Bigmac - which pellets would you recommend?

[Rez 4,961]

I know your asking mac, but I would look at the H&N range. I use FTT's in my twenty two, which are faultless to be honest and Barra Hunters in my 98. They are heavy mind, 10.6grn, and to be honest, I feel like I need to be on top form to get them to stack, however when they do, they properly do. Can beat good old H&N FFT's though. Do choose the head size well though, as the 4.52 are ultra tight fitting... Like finger bustin' tight.

 

Re the rifle, get it apart, clean it up, see what happens then. All will come good

I have to add my recommendation of H&N FIELD TARGET TROPHY for any Weihrauch spring rifle. Headsizes are an important factor in how accurate these are from your barrel and, you haven't told us what calibre you son's HW97 is. But to help you with a solution to either calibre.

 

If it's .177, you can start at 4.50, 4.51. or 4.52 to 4,53.

If it's .22, you can start at 5.50, 5.51, 5.52. 5.53.

 

I shoot with a .177 HW97K in my collection and it loves these pellets in 4.50mm headsize.

 

You can find which headsizes the pellets are by looking on the underside of the tin where youy will find a label. At the top of the label you will see the brand plus the headsize of the pellets.

 

Try them and experiment with them all. These are blisteringly accurate pellets in my .22 and .177 Weihrauch spring rifles.

 

Spring rifles are every bit as accurate as PCP rifles...If you know how.

 

Read my pinned post Spring Air Rifle Shooting in Technical section. I've tried to cover as comprehensivley as possible, the technique for shooting a spring rifle to precision accuracy standards.

 

Best wishes.

Just an update... i have cleaned the barrel will a bore snake and re-zeroed with H&N FTT 4.5's and the rilfe is not shooting perfectly at 25yards.

 

Thanks for all your advice, very helpful!

[bigmac 97kt 13,806]

Jsb exacts group well in 177 and in 22

If you have cleaned the barrel then you will have to put a good few through her to lead the barrel back up

 

and the groups should get tighter as you go

Hi head sizes on the tin don't actually mean very much they might be an indication that a third of that tin are on the large size but maybe not .

It's all about what die size was used .

Most of the h&n that I have used have been really tight skirt wise never measured the head but they seem very big.

Go on intershoot if you want get serious about batches etc.

Back to the topic at hand a 95 should just be very accurate and not pellet fussey so it's unlikely to be down to pellets in my opinion .

I have a 35 I am currently trying to work out what's going on with ,it is at least 40 years old though .

My 37 year old when through a dodgy patch after I had rebuilt it in the end its laser acurate with only one barrel shim and not pellet fussey though scopes do need to be very off centre .

Also barrel bolt tightness is critical.

I think he meant to say "the rifle is NOW shooting perfectly at 25 yards"
