My LGS had quite the selection of primers. About 30,000 primers of all sizes. I hope you find some in your area. I think online is going to be tough because people are literally scanning for them and snagging them up as they get them and many are back ordering and no one knows how back logged they really are. I think your best bet is to have cash ready to drop and keep checking the local shops.Near impossible to find. Anyone have a line on them online??
The trick IMO is to be diligent in going to the LGS every day. I went into 5 different gun shops this week, and 4 of those five I went to 3 times. I entered gun shops 13 times this week and netted 1100 rounds of 9mm bullets, and 1000 primers. So you just need to be there. Also, I always say HI to the guys and that helps because sometimes they will stash something back because they know I will be there on a regular basis. If you communicate with them and befriend them they will get to know you and then they might hold something for you.My local LGS told me yesterday that all he has for sale is on *********
