Gun City has a chequered relationship with most people on this forum but they do sometimes offer some good deals.
No I don't have any connection to them other than I just bought 2 cases of this ammo.
CCI Standard Velocity .22LR
They are doing cases of 5000 for $429.
This is at least $50 cheaper than anyone else around from what I have seen.
I have a hungry Ruger 22/45 pistol and Ruger SR22 Rifle that both love this ammo.
