Brass from shooters is getting hard to find since most of the folks are getting into reloading. I had the same problem with 340 Weatherby brass. If you Gioogle 264 Winchester you will find quite a few places that sell it and you can decide if it is in your price range.
Critter, Most places are on backorder for new 264 brass, I have a couple thousand rounds loaded but our prairie dog season is close so it won't last long. anyway I'm still looking for GOOD used brass if anyone has some they want to sell.
I cleaned out my local Sportsmans Warehouse when it was shutting down. But now that I think about it, I remember there being some at the Loveland store last week. If you're still looking, I can hook you up, assuming it's still there. PM me if you need it.
Want a quick and inexpensive call for Moose? Take an empty 32 ounce coffee can, and make a small slit in the bottom, only about a quarter inch. Then, take one of those really big red rubber bands, the ones that go around big folders. Cut the rubber band to make one long piece.
Now, thread one end of the band and tie a knot on the outside of the can so it won't pull through. Cut the band off on the other side so it is even with the top of the can.
Now, wet your finger,...
