Thread: just Varminting - how far was your longest shot on your last walk

I know what 3" is. The KZ on a bunny is 2" at most, even a large hare, 1" for a headshot.

Anyone can fluke 3 shots, I'd like to see his 100 with 10 shots on, I'd pick he's holding 2 MOA or wider.
From my experience the opening up of groups occurs as the bullet goes transsonic. Which as said is about 120m for most brands/barrels. The heeled 22s aren't very aerodynamic in the first place. and once that shockwave overtakes them they can go to fuck pretty quick.

If you had been on here longer Pimms you would have seen some of Rossis earlier postings. He has got some very specialised long-range centrefire gear and we can be sure that any wounded rabbits are dispatched immediately. The effective kill zone is bigger than you think, depending on position. If a bunny is sitting up face on or facing away a hold at the top of the head gives a vertical kill zone of 180 mm. I am thinking wind may have had a hand ruining the 150 metre group

i have used subs out to +300 yards on paper/steel and Rabbits but there are problems, the Supers longer Point Blank Range is easier to use when your in a hurry in the field.
i have 2 X .22lr rifles, one for subs out to 400 yards the other for supers out to 200 yards . . . i was looking at some Rabbits passed 300 the other day with my Super setup and thinking the reticle ( mildot 3.5-10 ) is plenty fine enough with enough magnification and enough elevation to get out to 350 yards, thats enough to get me started on this path for awhile.

It is rather blanket. This guy explains it fairly well, or with better words than my self... The supersonic slows down, the point from super to sub Sonic is supposed to make projectiles unstable. (Transsonic) He seems to think around 120 mtrs. Which it might be, depending on the cartridge it was fired from.
So it seems backwards that the faster projectile leaving the barrel is worse for long range, but only because of the transsonic point. .22 might be 120 like he says.
Some 308 loads are a bit before 1000. That's why I say your long range .22 rimfire efforts may be better with subs, more predictable, or stable.
I haven't personally had this problem but I've heard of it a lot. But by all means put a target up and try, let us know.
