HW77K Grouping or Not!

[Koz]

I picked up a cheap one a while back.

The innards were smothered in red grease.
I've cleaned it up and chucked in a Titan spring giving 11.5ftlbs with AA/Daystates.

So far I've put AA Field 4.50, Daystate FT 4.51 and RWS Hobbys.
The Hobbys are the only one's that'll group.
I've yet to try AA or Daystate 4.52s.
Maybe the tighter fit will help.

Any similar experiences?



I note in searches that FTTs go well in 77s. I'll give them a try as well as Bobs Exxies.

For 0.177, try H&N Silhouettes. I've got a HW77k mk3, my pal has a HW77k mk1 and they have very different tastes in pellets. Newer ones seem to like AA fields, RWS Superdomes, H&N FTT and probably loads of others (try RWS Super H-points too). Not sure about the older HW77 models, other than Silhouettes...

Scrounge some 7.9 premiers, they always seemed to work in my 77.

I suspect this is an older model.

Is there somewhere I can check the serial number against it's age?

[Numb Nut]

Dunno about serial numbers...but the various HW77 models have other small differences - the underlever catch in particular and the number of scope mount arrestor holes on the back end of the cylinder. The exploded diagram from chambers web site shows the 3 styles of underlever catches. The newer HW77s have 3 holes for the scope mount's recoil pin, while older rifles had just 2. <img src="http://jsramsbottom.co.uk/bbs/e/icon_smile.gif" alt="Smile" width="15" height="15"><!--graemlin::)-->

Mine, a mk 3 clover leafs at 30 meters with super domes and ffts in .177. Super domes are nice and light so they fly flatter to.

[Numb Nut]

I think the newer rifles have plastic spring guides (with a steel washer base) while the older ones have a steel spring guide with the end cut into 4 'legs'. There is also a difference in the loading port shape/size...can't remember the details. <img src="http://jsramsbottom.co.uk/bbs/e/icon_smile.gif" alt="Smile" width="15" height="15"><!--graemlin::)-->

My old HW77 used to just adore the Bisley superfield pellets!

FWIW my (late model) 97K relates extremely well to the 14.66 grain FTT's.

Here's the exploded diagram from chambers. Compare your rifle's underlever catch against the 3 in the picture (top left) to identify the mk of your rifle.

Difficult to identify the differences on the Chamber's line drawings.

However, the spring guide is the opened out tube cross type and there are three arrestor pin holes on the top.

The number is 1182580

Underlever catches, from what I tell mk1 has a spring loaded ball indent, mk2 has a slide operated catch on the underside and mk3 has a push button on the front end. Mine is a mk3 with serial number 1486xxx. I'd guess yours is a mk2. <img src="http://jsramsbottom.co.uk/bbs/e/icon_smile.gif" alt="Smile" width="15" height="15"><!--graemlin::)-->

It has the button on the front.
The button is actually "blue"

Maybe it's an early Mk3.???

I've emailed Weirauch.

Maybe they can put an age to it.

[Numb Nut]

Could be a mk3 but the metal spring guide made me think it was an older mk2. They might have changed the spring guide to plastic during mk3 however. Given that it has a front button it must be a mk3 (erm...I think)! <img src="http://jsramsbottom.co.uk/bbs/e/icon_smile.gif" alt="Smile" width="15" height="15"><!--graemlin::)--> So back to your original question...try FTTs they should be really good in a mk3 HW77.

[Koz]

Confusing isn't it? <img src="http://jsramsbottom.co.uk/bbs/e/icon_biggrin.gif" alt="Big Grin" width="15" height="15"><!--graemlin::D-->

Cheers mate.
I'll give the FTTs a try.

[Koz]

The FTTs did the trick.

I tried to get 4.52s but had to settle for 4.51s

So far getting sub 1/2" at 25yds kneeling.
Plus the odd flyer (down to me I suspect <img src="http://jsramsbottom.co.uk/bbs/e/icon_wink.gif" alt="Wink" width="15" height="15"><!--graemlin:;)-->)

Turns out the old girl is a 1990 model.
Weirauch were helpful with age info and pellet tip.
