.20 calibre

[gsxrman]

Sorry - I did misread the 90% thing.

My 20s were always more resistant to wind than my 177s and that's a real world advantage, at least it was for me.

I totally agree, that's why I test all pellets out doors.
So far I have found nothing to compete with 7.9 grain Premiers, there BC is high, they are short but in real tests out perform most others including most of the JSB range.

and in a PCP, 10.3 grain .177 JSB heavies are amazingly wind resistant...

[PCPShooter]

I find JSB Heavies great for killing, and the best for wind resistance (not that'd I'd hunt in anything other than the mildest of breeze with an airgun, because that's just plain unethical behaviour, like taking shots with diablo pellets at uk power limit beyond sensible ranges)

I'd never use 7.9's for hunting, the most ineffective pellet for killing generally I found.

Of course, a bigger hole is better, hence 20 Cal King

The audacity of some people eh.....
Using the Mickey Mouse calibre and 7.9 grain pellet, the cheek of it.

Accuracy is what counts. End of, not extra .5mm diameter hole or an extra/less couple grains.
Clean in the head and they wind up dead. Stone dead. Shoot a human with a .177 projectile through the ski mask with enough power to go right through the brain and you would kill them too.

Sometimes people just need to be "shown" the way. Been on many Rat and Pigeon forays with other shooters using all sorts of rifles and calibres. They all end up asking what I'm using.

I find any pellet of any calibre to be perfect for hunting as long as I can put it in the right place

But, as I said at the start, they also cancel the perceived advantages of .177 being fast & flat

Then all say "I'm not using what you use. You'd be better with a 22"

What's needed is a test with .177 .20 & .22 H&N FTT's

Under controlled conditions

All shot @ the same FPE

A set zero of ?

A set of mediums for impact tests

And all chronographed @ 40 yds for retained energy

Or Phil Prices AGW test from 2010 of the main 4 cals in sub 12 Rapids using JSB exacts

There was a chap in America did this with accupell at fac levels (but only in 20 and 22) and the difference at 100 yards was staggering to be honest.

Once the power level ups then everything changes. Just look at the .17HMR.

Flatter shooting makes hitting tiny vitals that much easier at the longer ranges.
A pellet stiletto, knitting needle, only requires a few lbs of force to cut/punch a path through to them.
Play with pellet weights then you might get a light .20 to seem similar to a heavy .177. Or a heavy .20 similar to a .22. A fun exercise but it is still shot perfect placement that counts.
Lastly, the quirkiness of springers probably negates such tiny advantages as no two springers are exactly alike. The limit to any combo is hitting that polo mint.

somewhat, but not completely; they are still flatter than the similarly weighted H&N, due to an exceptionally high BC, but they are not well suited to springers.. unlike the .20 H&N

[MrGreengrass]

If you have a .177 that shoots the Zan 10gn accurately...
and I have X3 that do..they take the wind better and retain more energy than
any conventional pellet.

[Bob6500]

I actually found 20 cal jsbs easier got than the 22 cal last time I bought..20 cal in fac is just brilliant 🙂

[Muskett]

I should think that at the lower FAC powers then the .20 could rock. Certainly it seems the .177 doesn't like being overly shoved. Up the power more then the .22 comes great. Massive power then even the .25 smacks.
