Keep your money or buy something else.
Both the Colibri and SSS are POS ammos.
Each of them require special chambers and twists
to shoot anywhere close to "accurate",
and even then it's a gamble game.
I still have some Colibris left from some time ago.
They are 20gr, one of the lightest bullet heard of
if someone wants to use it in 22LR
(Colibri is 22 Long, NOT Long Rifle).
It requires something like 1:20 twist probably,
because in 1:16 twist bbls it shoots in the middle of next week.
It will not cycle automatics all the time.
SSS is a joke.
Theoretically it would require 1:9 twist,
but even US 1:9 bbls made specifically for that ammo
do not deliver accuracy.
As I said, keep your money or buy something else.
There are cheap ammos (bulk) out there with very good accuracy.
