20 Calibre saves a lot of hassle discuss

[Shed tuner]

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!!

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

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.

The .20 is a very underrated calibre most have not even tried it and gave it a chance that is why it has not taken off as good as .22 or .177 i had a rapid in.20 it was amazing the only big let down is pellet availability when you want them they just about out of stock everywhere and not many manufactures do them --i have not long sold it as this lead ban we keep hearing about worried me in being stuck with a gun i could not feed--so have gone back two now my main calibre .22 just because i can stock up with pellets the most i have a another gun in .177 but rarely use it and a small stash of pellets for it --if manufactures made more .20 there would have being more .20s sold over the years i can remember when if you wanted a .20 you had to buy a Sheridan pump up Then Theoben started offering them then later HW but it was then to late --we keep hearing about .30 and .35 these are not new back when i had a .25 Sharp innova when they were unheard of A barrel for .30 was available but no commercial ammo over here I think if Steve Harper had being taken up with his barrels sooner we might have been shooting .20s .25s.30s motr now

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

thats all that matters.!!

Absolutely love my 20 cal in fac.....

Absolutely love my 20 cal in fac.....

Try the jsb heavy in 20cal. If you need any al send you some.

Oh I bought ten tins lol..splendid combination

[gsxrman]

Wow, like cave man mentality. "Need big rock, smash puny creature". Accuracy is what kills period. Unless of course there is enough power to blow quarry up. I want to salvage and eat the rabbits I shoot, so clean head shots only.

.177 do produce smaller groups. Variation in slugs should be measured as a percentage and not a constant across calibres. The only constants are the range and the conditions. At 30+m my prems go through the same hole, how on earth can a larger calibre beat that., and they defo wont at 55.

Reason for FAC, produces flatter trajectory and can use body shot. 7.9 grain .177 is probably as flat if not flatter than a 16-20 gran .22 FAC, unless ridiculous power level but then accuracy wavers with pellets as they cant cope so ya switching to something hence just use a rim.
Body shots, I haven't taken a body shot for years and never will again.
I just don't get the "compromise" as .20 is not as flat and forgiving as .177 and those that believe in hitting power is a must, they don't hit as hard as .22. There go pointless. I'm not saying they wont do the job but they don't offer a big enough advantage over the other two calibres to warrant changing unless they become the new .177 in lead free.
