Theskyfox Posted January 21, 2014 Report Share Posted January 21, 2014 Hi Guys, Looking to get my Air Arms TDR soon in .177. One of the first jobbies I have had a quote for is to get a regulator fitted to improve the shot count and consistency. As a part of the service, you also get a "tune up" to a pellet of your choice. My question is...what would be the best pellet to get the gun set up with? I'm looking for a reasonably heavy pellet that can be set to 11ftlbs, and do not want any risk of a heavier pellet taking the gun over the legal limit. -Andrew Quote Link to comment Share on other sites More sharing options...

-Mongrel- Posted January 23, 2014 Report Share Posted January 23, 2014 Heaviest from decent manufacturers I can find are H&N Rabbit Magnums 15.74 grain followed by, Crosman Premier Ultra Magnum 14.3 grain. Would you really want to use any heavier? Eun Jin apparently produce a 16 grain pellet but never heard of them so won't add them in. Do you really need such a heavy pellet? I only use a 10 grain pellet for hunting so would be asking them to set it up for what I use or a touch heavier. Quote Link to comment Share on other sites More sharing options...
Theskyfox Posted January 24, 2014 Author Report Share Posted January 24, 2014 Hi, Thanks for the replies, Well I'm not specifically looking for a heavy pellet, I'm just aware that heavy pellets give more power (to a certain point). I'd normally consider something like a 9.5 grain Logun Penetrator. After reading lots of scare stories you see on here and elsewhere, I'm just trying to work out what the best weight is give you the best performance whilst giving enough leeway to prevent any issues. 21 grain piledrivers - is that in .177? thats insane, who would actually use such a weight sub 12 ftlbs?! -Andrew Quote Link to comment Share on other sites More sharing options...
-Mongrel- Posted January 24, 2014 Report Share Posted January 24, 2014 If you're accurate, 9.5 grains is plenty enough. Airgunning is 90% shot placement. Hit your target in the right place at a sensible range, it will be killed. Quote Link to comment Share on other sites More sharing options...
norfolkgoose Posted January 24, 2014 Report Share Posted January 24, 2014 (edited) You should not go over power with heavier pellets as the regulator has a set level or power it delivers regardles off pellet weight un like unregulated power ... my bsa r10 mk2 has less power useing blisley mags than rws super or field ! bsa r10 is regulated as is my hw100 my webley raider 10 is not and does creep up .

-Mongrel- Posted January 24, 2014 Report Share Posted January 24, 2014 Interesting, I thought the regulators regulated the amount of air released per shot to keep the power the same as the reserve depletes. I didn't know they could 'sense' the pellet weight being used. Quote Link to comment Share on other sites More sharing options...
Good shot? Posted January 24, 2014 Report Share Posted January 24, 2014 (edited) I wouldn't go any heavier than Crosman Premmier Ultra magnum in .177 cal and at 10.5g is well heavy for .177.I do think that at that weight you would begin to loose some of the flat trajectory of the .177 calibre. I wouldn't bother going any heavier than 8.5g at 11.5 ft/Lb and concentrate on accurate shot placement. (error correction edit) Edited January 24, 2014 by Good shot?

norfolkgoose Posted January 24, 2014 Report Share Posted January 24, 2014 Have a read of one to baffle the brain on air gunners pw... I will try and find the page I was looking at on net on put the link on here. Quote Link to comment Share on other sites More sharing options...

-Mongrel- Posted January 24, 2014 Report Share Posted January 24, 2014 Right, just read that, and nowhere can I see where anyone's saying that the power output is regulated. A few people are saying that the power output is the same regardless of pellet, surely the only way that can be done is by regulating the amount of air released as I suggested. They all seem to be suggesting that there would be some variation with different weights, basically a heavier pellet pushed out of the barrel with the same amount of air will be travelling a bit slower, but being heavier it will carry more energy at POI. It's the correlation between the two. Why else would you need to put a pellet weight into a chrono when power testing? Quote Link to comment Share on other sites More sharing options...
evo Posted January 24, 2014 Report Share Posted January 24, 2014 (edited) and you now know why the brain is baffled, have to agree with mongrel on the following basically a heavier pellet pushed out of the barrel with the same amount of air will be travelling a bit slower, but being heavier it will carry more energy at POI but I was lead to believe the heavier the pellet the more power,,but this does not seem the case with regulated air rifles,but does seem to be the case with unregulated ones though, I was also lead to believe the reason we have our air rifles regulated was to give a very EVEN power curve wether your gun was full 200+bar or nearly empty ie 100bar Edited January 24, 2014 by evo Quote Link to comment Share on other sites More sharing options...
Theskyfox Posted January 24, 2014 Author Report Share Posted January 24, 2014 (edited) Thanks for the replies. Ok, My experience so far has only been with unregulated rifles where generally heavy pellets have resulted in higher ftlbs. I wasn't aware that regulated rifles didn't suffer from this - and its good to know! 8.5Grain at 11.5 ftlbs sounds about reasonable. I think I'll have a chat with the BTAS guys too and see what they recommend. -Andrew Edited January 25, 2014 by Theskyfox Quote Link to comment Share on other sites More sharing options...

My regulated AA 510 chronos higher with Bisley Mags than with AirArms fields. Quote Link to comment Share on other sites More sharing options...
