PV, Midway and Natchez have all had some Bullseye in stock fairly recently... maybe Graf too iirc.

I don't use the stuff myself, but I keep an eye out at the recent arrivals at Graf pretty regularly and was on the prowl for 2400 for quite a while before I managed to score some a couple months back. Alliant stuff just seems like it sells out faster than other brands... guessing thr supply is a bit shorter than other brands.
