Ammo question for competitive .22LR

[u/edyuster]

I got a CZ 457 MTR Varmint and I’m looking to shoot competitively next season/ year. I did some small batch of ammo testing at 50 yards and the best results was between the SK Rifle Match and SK Long Range Match. I tried 100 yards and the SK Rifle seems to be all over the place.

I know .22LR ammo can also vary by lot. By the time I purchase more I’m not sure how the new lot will behave.

So the questions here are:

What’s the best approach to testing ammo and getting a large amount? Do I purchase a test batch at the beginning of the season and buy a boat load it quickly after?

I’m seeing a drought in ammo, do these come in waves and I just have to keep checking retailers? or do I need to preorder them so I get the amount I need?

Also for anyone shooting ISSF .22LR as well same questions. Looking to get a Pardini and doing this process but it seems like the pistol ammo is in even shorter supply.

Seems like sk long is sold out everywhere
