I'm planning ahead for the completion of my Tango-51 and ammo is on my checklist. Would anyone be able to provide some insight into how to best locate between 500 and 1000 rounds of matching lot 168gr fgmm? I have been monitoring this forum's for sale section along with the ARF exchange. Does anyone have webstore/forum recommendations that I should be periodically checking? I have a bunch of time to work with since the Tango was only ordered 2 months ago. Thanks in advance!
