HW30 Tune

[NickG]

The UK spec factory spring was used if i remember Pauls was doing about 8.6 with 8.44 JSB pellets. A kit was fitted to a second rifle and that have now fired well over 500 pellets im told its putting out 8.8 ft lbs. Im finding it hard to believe that the power increase on these rifles Pauls went from just about 7ft lbs to 8.5plus. I have now bought a new 177 to see what power i get with this one. im at the moment trying to get a higher quality spring but this will not be until the new year.

Hi Lyn,
If the spring you are getting is the same spec but longer for the 30 I would be very interested in trying one.

Anyone know the stroke length, just wondering how much it could be increased , see what the potential is for upping the power a little. at 25 mm 11 fpe is available from 70 mm stroke but with a big spring .
I have had a 21 mm tune making power from 70 mm stroke, (on a softish spring) so thinking maybe aim for 10.5 but at a shorter stroke, obviously easier with a .22, I would be wanting it in 177, call me ambitious 🤣.I don't own a 30 so just thinking out loud ☺️

If you get the piston out of the old HW30II and replace the leather washer with an Original Diana 25mm one you can get some extra stroke, or so it seems.

After receiving my glided 30 from Lyn last week at the bash I finally scoped the 30 up with a weaver 4.75 x 40 for a zero session. Well out 25 yards the .22 gives nothing away to its little calibre brother at all. I'm still taken aback how accurate these are even by sub standard shooting these days. Mach 1.5

Sounds brill Paul

I really ought to revisit the 30 as I’ve unfinished business especially with an unfortunate sour taste one left but hoping that one was perhaps a runt.

Took its bigger brother out today the HW99.This one sports a CS700 stock and a PS Stage 3 tune. Out to the same distance nothing between the 30 and the 99. Mach 1.5

After reading this and other threads about the 30 has peaked my interest . I have never shot one or even handled one but I feel I must scratch the itch lol

Yes. This you must do, Don. You will not regret it. It might even become your favourite rifle. But you might have to do the anti-galling mods.

Do it, Nick.

Nick would, most likely, mod the piston, fit one of his rings and gain even more stroke, Al.

Yes, methinks you should, Nick.

Marvellous! And another lovely, sweet-shooting, lightweight HW.

Well I thought about it and the decision was taken out of my hand by our Son Dougiefn12 and his lovely family today for my Birthday . I was presented with this little fella in .177 . Cant wait to have a shoot tomorrow

[TonyL]

Happy belated Birthday.

I hope you had a great day. Receiving this must have made your day.

Enjoy.

I can see some tuning coming on within the coming weeks too can’t wait to see how this little beauty turns out.
