If i can shoot through 100-200rds out of the box with no failures, its is reliable enough for me…
There are some platforms I’ve shot that have gone 400rds out of the box trouble free unless unless I used questionable ammo and got it to fail (using ammo in bad condition) so it was the ammo’s fault not the firearm.
My last 2 .22lr platforms I picked up have been amazing and are cycling better than I would have expected.
