  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

  5. Postings on Politics, Religion & Controversial Off-Topic Material

    The majority of users do not want to read about these subjects and people have left the forum as a result of it – this is after all an 'Airgun' Forum. It’s all very well to say they don’t have to read it if they don't want to, but as most of us use the ‘New Posts’ button there is no easy way to avoid it.

    All AGF staff members are in favour of people being able to discuss what they want, but we have to draw the line somewhere if it is upsetting other users. We don’t want to read about these topics either.

    IMPORTANT- The discussion of politics and religion is no longer allowed anywhere on the forum (including the Adult section).  The only exception is if it's airgun related - they must be put in the Airgun Related Politics section..

    We will not tolerate bullying or personal attacks, racism or any other offensive 'isms'. we will remove these topics from the forum, we will not give you an area where you can abuse each other. We will not hesitate to ban offenders.

    It’s offered just in .30 cal but actually... I’ve seen 12 ft/lb option available in one place, but it’s quite funny (and stupid) as it should be set at max 325 fps to stay within that limit :rolleyes: so imagine bullet drop at 25 yards (probably max range) :D

    I was a bit quiet recently. But there was a good reason for that… fine tuning my R5. It’s part of fun, part of the game (at least for me). It’s just like with cars – even the coolest latest sport car can be tuned, not just outside but also inside – chip tuning, engine tuning, exhaust tuning, etc. Thanks Lord it’s a bit less complicated with airguns, and waaaay cheaper, LOL! Anyway, long story short – one day I was asked by my buddy from NZ if I’d be willing to take part in Huma kit development for R5. OK, why not? And as a result I was sent a prototype of R5 performance kit (or power kit if you prefer that name) to try in my R5. Of course I was more than happy to try something new… but it was not as simple as I thought! The Prototype kit was not threaded correctly at the connection end (hence the name – prototype). So I was not just testing and playing with new kit, but also tried my machining skills on lathe, with a bit of help from my father in law (who is really good at it… and his shop is quite equipped too). BTW, the thread connection between reg and plenum is not needed at all imho. It was made to remove the whole unit easier from air tube but... it disconnects anyway when you're unscrewing the rear plug, lol! So it should be either ccw thread or... just no thread at all. It's not designed to seal on that thread anyhow.


    humar5_web.jpg


    Small digress here: I really like the way Ed design his airguns (as an overall concept). It’s just SO EASY to work on them and R5 is good example. Changing regulator setting takes just couple of minutes. Of course, I know there are other guns with regulator settings / manometers on the outside, but none of them looks so ascetically good imho. R5 looks like a gun and can be used & treated as a regular field gun. And the new electronic manometer makes that overall look even better. And BTW, when disassembling/assembling R5 be sure to tighten the breech/ hammer block really well, otherwise it can get loose with time (it’s not needed for reg adjustment, but I quite disassembled my R5 when I was playing in a shop). End of digress.


    Anyway… after some time spent behind lathe finally I built a hybrid of original plenum and valve (very good valve let me tell) and Huma’s regulator and additional plenum space. I tried many different settings - almost anything between 110 and 130 bar. After fine tuning I could easily get 44grain ammo flying at 900+ fps (about 25-28 shots per fill) with 120, 125 and 130 bar on reg. A 120 bar it required really strong hst, so I decided to set my reg at 125 bar. That way, depending on need, I can get either high power (900 fps) or very efficient shot count at slightly lower muzzle enegry (850 fps, or 260 m/s). But that ‘low energy’ is still close to 100 Joule at the muzzle and 50 Joule down range at 100m. So it’s not ‘low’ by any means.


    r5custom_graph.jpg


    So as you can see with my new custom setup (it’s really nice feeling to have some parts machined by myself inside my own airgun) I can get quite significant number of shots. Starting from 251 bar it shoots really good up to 125 bar reg setting, than goes up a little bit (+3m/s) which is an usual peak after getting reg pressure, and goes slightly down to 256 m/s at shot #42 (shot at 106 bar). Some would say that it’d be better to stay at #40 as last one, depending on what is your expectation. Still 40 very good shots is quite a serious shot count. As a side note – originally I could get about 30 good shots at 260 m/s (plus 2-3 more usable, just as here) which was also not bad. 10 more shots is not 'day and night' and .30 cal still eats air fast so... get a bigger tank if you plan to get into .30 cal territory! Could that be tuned for even more shots at 260m/s? I guess so. At lower reg pressure setting. But I’ve chosen a compromise of tuning muzzle energy easily between 850 and 910 fps with just one reg setting, just by turning hst. That’s how I want my gun to shoot. And with 285-290 bar fill I could get 50 good shots I guess… I’ll check that when I top my tank up to 300 bar again. I hope Huma can use some of my findings and suggestions for the final R5 kit. And I learned some new skills too ;)


    To make the update complete – I practiced some more at the range, but this time I was very picky on ammo. I inspected each pellet for any sign of deformation, scratches, etc. and my best 5 shot groups were 26 and 29 mm across (#1 and #2 from the left in the pic below) and groups I considered ‘average’ were like the #3 (42mm). Of course, I’d love to shoot everything at MOA or better, but it’s surely MOA (1”@100y) capable airgun.

    And last but not least… obligatory ‘for fun’ shot with my Fuji. I know it’d be more appropriate for November but hey, this year we have November weather in December here (as you can see):

    I know it was a long update but… maybe worth typing. At least enjoy last pic, LOL!

    And since it's a gallery... what about another pic? I know it's a bit different, but still a bit on topic since I've got R5 in my hand. I really like that kind of photography, keeps me relaxed when I work on it in the end of the day like now. Just for fun.

    Excitement is up again!!! It's a NEW YEAR... and something NEW just arrived. It's still in a box. Shooting range already booked for end of the week.

    I believe that this can be another factor, which could tighten my 100 groups even more. Actually I had no problem to use my Vortex Diamondback Tactical on contrasting target and at 100m the parallax was fully compensated BUT this scope should take me to another level up in accuracy...

    In my excitement I didn't realized they shipped too low rings with the scope. But I should have a replacement delivered from my local Vortex dealer today.

    In the meantime - what about a shot in the morning winter sun? Hard to believe it was taken end of December. It's not kind of winter, which I remember (when I was a kid). Should be all white...

    OK... there is time for photos, time for tuning, but also time for actual shooting. And last days was mainly shooting for me. As I mentioned I upgraded in couple of areas, and each one brought positive effect in the end. First of all I selected my pellets - both visually and also weighted them all. And the weighted / selected pellets were put into full-foam lined container to avoid any damage. And of course upgraded my scope from Vortex 3-9x40 Tactical (very good glass) to 6-24x Viper HST, which changed a lot! And last but not least I also built way more solid shooting stand out of sand bags (added side bags to stabilise R5 side-to-side). So I tried to eliminate any variable factor I was able to. And here's my stand now:

    r5_jan18_web-1.jpg


    And the results.


    r5_jan18_web-2.jpg


    That 'opened' group on the right is 31mm edge-to-edge (24mm c-t-c) and the tightest group was just above 21mm edge-to-edge (so about 14mm c-t-c). So even if we exclude that crazy tight group of the day as "the lucky one" (it must have been a lucky group, I’m not that good... but it's still there) that R5 with good scope and selected/weighted pellet can potencially group pellets at hair below 1" at 100m (which is 109 yards to be exact). Off the sandbags of course.


    r5_jan18_web-3.jpg


    I think it's all I need in .30 cal airgun. Now what I DO NEED is even more range time and more pellets through my Matador. MOA is good enough for me.


    And last but not least - field picture for you, winter came here, finally!

    Cheers!

    What about one more photo? For me, personally, that R5 looks just amazing. I like that 'gun look' muscular aesthetics a lot, can't hide it. And it's so shootable too!

    Such a nice first post... oh well, welcome to the forum.

    And no, my R5 works fine after more than 10 tins of 44 grain JSB. Somehow I managed to assemble it well enough after my internal mods.

    Great news. Did u add any mod or special part to solve the issue? I got 2 R5’s standard and long, and both have the sale problem, no matter how you tighten the screw...unfortunately its a big disapointment for me, the gun is so well made and solid, rigid...except in the most important part, where all the stress of cocking and the hammer tension happens...i found the rifle super accurate and pleasant to shoot, and would love to solve this breech issue in a way. Would appreciate your advice. Tx.

    I'd recommend contacting your local dealer. I'm sure he can help.
