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.
Jim Zumbo, Craig Boddington, Ron Spomer and Wayne Van Zwoll are all solid contributers to the modern hunting literature. Through their gifts (both hunting and writing) they make us better hunters. Whether it is letting us learn from their mistakes or by teaching us new techniques,they help us harvest more game. But I suggest looking to the oldies, the fathers of the outdoor writing craft, to learn tricks that you might have not used.
I chose to shoot the 270 winchester because I grew up...
