What calibre is it?
I got the service kit last week and got a chance to fit it today. Well it was the first time I have had a springer in bits and it was a rather easy job to do. I will admit I didn't polish the piston I just fitted the replacement spring, guide and top hat. But the difference in the way it shoots it's like a different gun. It's smooth to cock and when fired its got a gentle but positive nudge to it. I didn't fit any of the adjustment washers and after 20 shots over the crono it running at a nice 9.9ftlbs. I'm assuming this will rise slightly as it beds in and settles down.

I wish I was in the land of cotton.
Sounds very good.
One slip washer might take it up a tad.
Apparently what you want is about 10.5 ftlbs with a 177.
You've got me thinking now. My 99s is in 22, but I'd love one in the smaller calibre as well.

I will check it after a tin or so of pellets and if it's below 10 still I will add a washer to bring it up to 10.5. But the way it's shooting at the moment I don't think I will. It's not very hold sensitive and I'm getting sub 5p groups at 20 yards so I'm not grumbling at the moment as it's more accurate than I am.
Very encouraging.
Thanks for sharing that.

Make sure you keep an eye on the stock bolts as they can work loose after a while

I to have just been playing with a 99s in .177. I purchased it second hand and it was doing about 10.5 ft lbs and a little harsh so I stripped and changed the spring, fitted a piston sleeve and did a little smoothing. It went up to a tad over 11 ft lbs and was still harsh. So stripped again cut a coil off the spring , flattened and smoothed and added a thin booster washer. Now doing around 9.5 ftlbs and a lot nicer to shoot.
Perhaps a top hat would provide a smoother shot cycle in addition to the above.
I wonder if around 9 - 10 ft lbs in .177 is the ideal power for these little rifles and that full power is more suited to the .22 version.
Excellent kits....
Nice one mate, enjoy shooting your 'new' gun.

I'm enjoying my Wonky Donked TX so much I still haven't fitted his kit to my HW99 /HW50 yet... Really interested to see how the.177 behaves.... I'll be aiming for no more than 10.5ftlbs.
Interesting post, cheers.

Just done my hw50 ( same as the 99), new guide, top hat and synthetic bearings on the piston, mine has the new style seal.
When finished it was 12.5 ft lb and bouncing, so collapsed a coil, and made the top hat from steel to add a little weight to the piston, now at 11.5 and shooting a treat.
