Thread: Why do .22s have such different accuracy with different ammunition?

Even different batches of the same ammo will produce the "splatter" you mention. There us a saying in the 22 benchrest and PRS circles "your 22 is only as good as the batch of ammo that you have at hand".

As a for example I have a batch of S&B HP subs that shoots lights out in most rifles, but it seems to be unique to this batch, most times its pretty ordinary. Generally the top of the line ammo shoots pretty consistently but even that can have indifferent lots - one of the bricks of Fiochi 320 I have is very disappointing.

In my opinion the "my 22 only likes xxx" thing is a bit overstated, I have a Lithgow LA101 and a Vickers martini that both shoot just about everything well, and most match ammo amazingly well. My friends big Annie match rifle does the same. Most people don't shoot enough groups and/or cherry pick their results, so most of the claims made on the interweb of "my 22 shoots consistent 0.5" groups at 50Y or 50M dont stand up to scrutiny and for some reason the shooter can't show a 5x5 of 0.5 groups.
