AIR GUNS / Re: 5.52mm vs 5.51mm pellets -...
Last post by gitano - Today at 08:33:04 AMWhat I don't know about air rifles would fill volumes. Yet here I am commenting. All I can add is my experience with centerfire ammo.
Bullets for the .44 Rem Mag come in two diameters: 0.429", and 0.430". The 0.429" bullets shoot "patterns" from my revolvers, the .430s shoot groups.
Soviet-made rifles have bores that range in diameter from 0.306" to 0.314". The larger the bore, the crappier they shoot. Small-bored rifles get .308 bullets, large-bored rifles get .311 bullets. I had a brand new Soviet M44 that couldn't keep all of its shots on a 4-FOOT X 3-FOOT piece of sheetrock at 40 paces!
From what I've read, skirt diameter on pellets is critical to precision. That said, 0.01mm is 0.00039". While "stranger things have happened", it would certainly surprise me that that would make a SIGNIFICANT difference in precision. On the other hand, if it didn't, why would 'they' make the two sizes? Personally, I'd expect the bigger ones to shoot straighter, BUT, I'd shoot the ones that ACTUALLY shot the straightest. (Duh).
Paul
PS - Regarding pellet resizers: To make 'em bigger, seems like a cone one could push into the skirt to 'over' enlarge it, followed by pushing the pellet through the 'tube' of desired size, would be a method for "sizing up".
Paul
PPS - Kinda wish I had an excuse to get a nice Pre-charged pneumatic rifle like one of those.

AUSTRALIAN OUTDOORS / Re: Teaming up on the foxes in...
Last post by branxhunter - April 30, 2024, 02:46:16 AMHello Gabe.
While I am sure the scope could be made to fit I'm not sure whether the cantilever mount would Sakos have a tapered dovetail on top of the receiver.

Last post by jaeger88 - April 28, 2024, 04:53:31 AMSorry, just re read your last message & you said TDR mags.
T R Robb himself, says he doesn't think pellet size makes much difference to accuracy, unless they are so undersized they don't engage the rifling properly. The sizer does make pellets more uniform though, & that's where he believes the accuracy improvement comes from. Probably using quality pellets of a uniform weight helps too.

Last post by SmokeyJoe - April 28, 2024, 04:50:46 AMQuote from: jaeger88 on April 28, 2024, 04:44:15 AMOK, well don't forget to dial in temperature, wind, humidity, altitude & of course, Coriolis effect as well.Aaah, i see. I was under impression the resizer could flare the skirt out to a slightly bigger OAD. Ignore me, I'll put my dunce cap back on.
Unfortunately the pellet sizer's I have can only size down, not up. So that's not going to help you at all. Is this a problem with the S200 mags, TDR mags or both ?. Ive not had that problem with my S501 .177 Mags.
Basically, in their simplest form, pellet sizer's are just a tapered tube, with the exit hole of the desired diameter. You just push a pellet all the way through. You can get em from Amazon for an Ayrton Senna.(10 English dollars), The better quality ones are made by T R Rob, & are adjustable.
I see, so I can see why the resizer would be nice for a bit more consistency, especially with some of the junk pellets I've seen!

Last post by SmokeyJoe - April 28, 2024, 02:19:08 AMYes of course. I'll just have to factor in the 'curvature of the earth' then I'll let you know.
Did you say you use a pellet resizer? Sometimes the pellets drop out of the TDR's magazine, I am wondering if a pellet resizer may help prevent that

Last post by jaeger88 - April 27, 2024, 09:05:09 AMYou WILL let me know which is more accurate at 1,000 yds though, wont you ?.

Last post by jaeger88 - April 27, 2024, 08:03:49 AMAre 5.51's better than 5.52's ?.
The answer to that one is................I don't know the answer.
Individual rifles are all different, yours could prefer either.
Trial & error is the only way to find out.

Last post by SmokeyJoe - April 27, 2024, 04:54:49 AMhaha, why thank you Sir.
No, I mean, why should I?
Ok so now i know where the label is, wanna enlighten me on the different choices and whether 0.1mm extra tight skirt (steady) will give me lasers at 1000 yards with 10.7 fpe?
Don't worry, you can give your real opinion, nobody will jump on you (unless I organise a seance for a second opinion)
