20 Calibre saves a lot of hassle discuss

[angrybear]

Yarn Yarn. Same old same old.
.20 is unnecessary and almost pointless.
For the flattest trajectory, tightest groups and more success on a FT/HFT course you choose .177.
For hunting of any power level, accuracy kills not size, so again the most accurate calibre, smallest groups etc .177 under 12ftlb.
FAC air .22 or .25, but I don't really see the point. If you need more range than FT ranges then use Rim or HMR.

Except .177 is NOT "the most accurate calibre" because no 'calibre' is more accurate than any other,
.177 is simply advantageous to shoot because the flatter trajectory helps cover minor range estimation errors.

& frankly, if you "don't see the point" of FAC-air, you obviously don't know what you're talking about there's far more to it than just outright range.

Oh & "Rim or HMR" HMR is Rimfire

Sorry .177 is the most accurate in the sense that it produces the smallest groups. They are lighter so less variation of size and weight which all effect accuracy and grouping.

So out to FT range what advantage does FAC air give me?

Ok, my bad, I meant .22 Rim or .17 HMR

where to start...

.177 does not produce the smallest groups.. you are confusing group size with "hole size" or calibre size.

lighter weight makes variations worse not better - a 0.1 grain variation is a bigger percentage of 8 grains than it is of 14 grains

FAC air advantages out to 55 yards ? You kidding right ? Lets go with flatter trajectory, less wind affected, and a far greater impact energy (allowing shoulder / heart / chest shots rather than a small and potentially moving brain).

Here we go again......177 does not produce a tighter group than a .22 at a known distance, but it is the most accurate due to errors with range, and the need to be so much more accurate in range estimation. Just look at the scores put in by people like Tench in both calibres. It is impossible to get quite as high a score in real conditions such as HFT comps and hunting with a .22

I used .22 for 25 years until going .177 for everything. .22 is great over 12ft lbs and works better there.
.20, waste of time due to lack of benefit and lack of choice and availability of pellets. Anyone who shoots any competition shooting sports knows that you need a good choice of pellets to make a big difference, in fact all the difference.
Regarding FAC air, I think that they have their uses in a very few specific circumstances, but I am looking at .22 and HMR next time I renew my SGC, and go FAC as well. I need 90 yards rabbits on my land and I dont think .22 FAC air will give me that.

Oh I am going to put up a .22/.177 debate next week just to get everyone going again!!

[gingernut]

The only problem I had with .20 pellets is that they don’t work in a .22 gun

As my shooting mate pointed out when my .22 stopped working properly

I have a couple of .20 rifles and some pistols
Make a nice change now and then

[MrGreengrass]

I have 177 .22 and .25
FWIW ..if I only had to have one caliber, it would be .177. not .20 because i can hunt, benchrest, FT and HFT with it and all the most accurate guns I have are in .177.
HFT500
FTP900
TX200
HW99S
Kalibrgun Cricket.

All four of the standard air rifle calibres have their place, my own experience with .20 is my HW97, which shoots FTT's beautifully a bit below 700fps. A good compromise between .177 and .22.

Wow what's that, Page 2 of the 'Ladybird' beginners guide to becoming a narrow minded tin chicken hunter ?
