wymberley Posted April 29, 2023 Report Share Posted April 29, 2023 This is a follow up to my Huma Regulator thread and I need some advice, please. Apart from a few pellets to try the accuracy (pleased) I've not seen much of this purchase having been waiting for the reg' to arrive and be fitted. I got it back yesterday and was hoping for an easy job as the 177 TH was to fine tune - just a quick tweak to reduce the power was all that took. Got this one second hand and now I've had a look there's no doubt in my mind that the previous owner - well, never mind!. I won't bore you except to say you ought to see the state of the internals of the shroud/moderator! I'm going to have to spend a few quid and am thinking while I'm at it should I change the barrel for a standard length one. At the moment it's running at a tad over 19 ftlbs. I have to confess that I'm somewhat disappointed with this having read the reviews - albeit with the standard 15" barrel versions - and c25 ftlbs would be good - or would this be too much to expect. All opinions welcome. Quote Link to comment Share on other sites More sharing options...
Mice! Posted April 29, 2023 Report Share Posted April 29, 2023 19ft/lb seems really low for 22 in fac. If you've had the Huma fitted somewhere should they not have set the power st what you wanted? Quote Link to comment Share on other sites More sharing options...
eddoakley Posted April 29, 2023 Report Share Posted April 29, 2023 I have a .22 r10 doing 36ftlb and it's awesome. Unfortunately it doesn't belong to me. It's been sorted by Bowkett and really is as smooth and accurate as you could hope for. Custom barrel and shroud and could easily do more than 36ftlb if needed. I think you could achieve more the 19 from the short barrel but might take a lot of trial and error to get accuracy. I'd think that you'd be better off with a longer barrel to get mid 20's or more. I do like a good r10 but still prefer a super10. Edd Quote Link to comment Share on other sites More sharing options...

If you've had the Huma fitted somewhere should they not have set the power st what you wanted? Therein lies the rub. I asked the guy to give me "whatever he could sensibly get balancing power and accuracy". He explained that he was going to do his best to get it done before he went away for a few days. I wasn't in when he rang to say 'twas done so I haven't had chance to chat. I'm getting the same as the shop owner when he gave it a go on the premises. However, it all started to fall apart in my hands because I then got not one but possibly two pellets stuck in the barrel not having noticed initially that the pellet probe/bolt knob had come loose so had to abort proceedings. The trigger blade coming loose didn't help either! I'm not an air-gunner so am not sure, but could the bolt knob have come loose because of an excessive load to cock the rifle because the hammer spring was messed about? Also I think I may have been using too much air. Will go again tomorrow now all is sorted and pay more attention to the pellet count.

Mice! Posted April 29, 2023 Report Share Posted April 29, 2023 Sounds like I'd be taking the gun back, the job has possibly been rushed, and 19ft/lb isn't nearly enough in 22. Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted April 29, 2023 Report Share Posted April 29, 2023 Sounds like the oring on the pellet probe is worn and allowing air to bleed out of the magazine area .that's the usual reason for stuck pellets . I can comfortably get 23 fpe from my bsa ultra with a 12 inch barrel . So a 15 inch r10 barrel should easily do 28 fpe and more . 19 fpe is hardly worth it in .22 cal . That's like 730 fps with a jsb jumbo 16 grn ,a sub 12 .177 will have a flatter trajectory. And flatter trajectory is the main reason for fac air.

I have to come clean - Oppo has reminded me (which I'd forgotten) that we did a quick check while doing a more comprehensive one on his rifle and did get 22 ftlbs but this got lost in all the faffing about with his. Going to make haste slowly. I did have a sneaking suspicion re the probe O ring - thanks 'Stu. I think there's two problems there. One is the seal and the other is that the probe did push a pellet into the barrel but with the handle well loose it failed to cock. This latter is now sorted. What I didn't say is that several times out of the c60 shots is that I had some at c500 fps which is another clue. It's pointless going again just to get the same result so will order some seals and then try. Another (temporary) problem is I don't currently know about FAC airgun parts. If I change a barrel is this a Firearms Dep't notification? I'm told by the RFD that even straight-forward one for one variations are taking 3 months. Because of the shroud assembly I have no moderator on ticket and would just go for the barrel without the shroud and even if the existing unit hadn't been wrecked I'd still need a new one (which I know is notifiable) - any suggestions for one of these? Heyho, nothing is easy! Quote Link to comment Share on other sites More sharing options...
wymberley Posted May 1, 2023 Author Report Share Posted May 1, 2023 Hands up for the O ring. Couldn't do much because of my wrists having already over-done it but gave the O ring a poke which was funny as they get harder not softer with age and it appeared to 'stretch'. It hadn't; it had split and was only in place because it had 'set' in its groove. Got it out and had a look with the glass - a very sorry state. It's going to be interesting to see what happens in a few days when the rings on order arrive. Quote Link to comment Share on other sites More sharing options...
Mice! Posted May 1, 2023 Report Share Posted May 1, 2023 Hopefully that means it's an easy fix for you 👍 Quote Link to comment Share on other sites More sharing options...
wymberley Posted June 6, 2023 Author Report Share Posted June 6, 2023 Well, I'll be damned! RFD warned me that D&CC Firearms are taking forever to turn-round any applications which includes simple variations. Submitted my "one for one" on 10/5/23. Just had a call. "Can you answer 'yes' to this question". Caller asks said question and I reply, "yes, I can". "In that case your varied certificate will be in the post this afternoon".
