Dangerous Brian Posted November 21, 2017 Report Share Posted November 21, 2017 Hi All My daughter shoots with a .177 HW30 which is a lovely little gun doing about 6fpe. The gun fits her nicely so I would like to hold on to it. Does anyone have any experience recommendations to make tuning one of these without spoiling it? I don't want to make an anti tank gun out of it but would like to flatten the trajectory out a little with a bit more pace.

Ultrastu Posted November 21, 2017 Report Share Posted November 21, 2017 No .It's not really possible to get much more out of the gun . The best way would be to shoot a falcon accuracy plus at 7.4 grns As these go flatter and make more energy Quote Link to comment Share on other sites More sharing options...
washerboy Posted November 21, 2017 Report Share Posted November 21, 2017 I would try and get her a hw99 to try the balance and feel of. Quote Link to comment Share on other sites More sharing options...
Dangerous Brian Posted November 21, 2017 Author Report Share Posted November 21, 2017 Thanks for your thoughts guys. I had a HW99 but she found it a bit too heavy which was a shame as it was a good little gun as well (might get back to one of those in a year or two). I have tried a couple of different pellet weights through the HW30 which make quite a difference at the muzzle. the Falcon accuracy plus should be better again on that front being lighter. According to Chairgun the heavier pellets lose less speed so arrive slightly sooner (which makes sense if they start out slower) but I have yet to have a play to see the difference first hand. Looks like some pellet packs need to be ordered. Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted November 21, 2017 Report Share Posted November 21, 2017 I have a .177 hw30 .It's lovely to shoot. It makes 6 fpe with falcons and about 4 fpe max with anything else . So if your gun is making 6 fpe with say 8.4 grns. Then expect quite an energy increase with the falcons. I looked at trying to increase the energy in mine. It wasent worth it. It's spook accurate and lovely to shoot as is. It would ruin that . I have more powerful guns .the hw30 is best left alone Ps 6 fpe will drop rabbits all day long out to 25 yds.

washerboy Posted November 21, 2017 Report Share Posted November 21, 2017 If it’s only for target practice and plinking I would stick with it and she will learn much more then trying a different heavier gun .Good luck with it, keep us updated Quote Link to comment Share on other sites More sharing options...

Probably best to leave it alone as you suggest as it is only for knock down targets. I would hate to ruin the way it shoots.

Ultrastu Posted November 21, 2017 Report Share Posted November 21, 2017 Then it's pretty healthy I only get 3.8 fpe with superdomes .about 4.2 fpe with 8.4 exacts .and 6.2 fpe with 7.4 grn falcons . It's fine if not better than it should be Quote Link to comment Share on other sites More sharing options...

Dangerous Brian Posted January 5, 2018 Author Report Share Posted January 5, 2018 You know when you have an itch and just have to scratch it.... Curiosity got the better of me and A Vorket kit got fitted. Power is up a little bit (about where I was told to expect it) but the interesting thing is power seems to be pretty consistent across the different pellets tried. The Falcons (Good shout Ultrastu) are the quickest which should reduce pellet drop but I am not sure how they will do in a crosswind being so light. Hopefully when I get a bit of light and a drop in wind I can have a look at grouping them all. All the best Brian Quote Link to comment Share on other sites More sharing options...
pelletcaster Posted January 5, 2018 Report Share Posted January 5, 2018 (edited) I tuned a HW30s .177 with some shortened parts of a partly used 25mm HW50 Vortek-kit. Spring, parts of rear guide, top hat and Vortek piston seal. Clean, debur, polish and MoS2-regrease as always plus some barrel bore polish awa trigger tune. Resulting in 8+fpe with any tested pellet (836! measured shots with 29 different pellet types and/or sizes) and a very nice shooting manner. Best pellet was JSB Exact Express 4,52 / 7,9 gr (381 measured shots) producing 8,5 fpe / 697,6 fps / max dev 2,8% / std dev 3,8 fps Scoped I could easily hold 20mm groups at 30 m shooting seated with foreshaft on stockhand on Caldwell but maybe the small gun was little bit over powered. Main problem for accuracy at this airgun was the ball barrel lock. Initially it wasn't closing repeatingly properly - as I had to find out due to improper fitting of cocking rod thus resulting in galling at the underside of the sys-tube and early stopping of barrel locking process. Quite some grinding off the uper sides of the cocking links solved the problem. Still think that this gun was quite a lemon but after a lot of work and pellet testing it shot quite decently. Anyway - no intention to touch one of those anymore. Edited January 5, 2018 by pelletcaster Quote Link to comment Share on other sites More sharing options...
