Sorry if this thread has been misconstrued but it is
NOT about 7MM Rem Mag vs XXX, but rather why it hardly made it to the list above.
This came about because a friend in the 1990s asked me the same question and I didn't have an answer then or now. My friend has been in procurement and acquisition (40+ years until he retired in 2008 IIRC) of special weapons and tactics program throughout DoD which included small arms. He said, he had seen many request for proposals for sniper rifles at varying chamberings but never the 7MM Rem Mag.
Anyways, with all due respects to all that contributed to the thread, I was soliciting primarily "real world/hands on experience" as noted above and I'm glad WR chimed in.
Now that we got that out of the way, let's move on positively.
WR, if I haven't said it before, thanks for your service to our great nation. BTW, I've always have a soft heart for the SOC world
, esp. now that my son flies with the AFSOC unit at Hurburt Field and currently deployed.
Thank you all!
