I would always start my search at Numrich Gun Parts Corp.Then look to E-bay,gunbroker.com,gun shows,pawn shops etc.
Assuing you mean a Winchester 190, it holds 15 22LR cartridges
50 is the norm, although you can buy bricks of .22LR with up to 600 in a single box.
The supply is improving, and you may find it at local gun shops or sporting goods departments. Some is available from on-line sellers. There has been a major shortage of .22LR for the past year.
Type into a search engine on the internet.
