If...if ARs and .223 ammo is supposed to decrease, then why wouldn't the price of Mosin Nagants decrease?
I have two $139 Big-Five Hex 91/30s. I wouldn't part with them for $250.
The Vallejo 9-10 February gun show sold-out of 7.62x54R spamcan ammo late Saturday or early Sunday morning. 9mm and 5.56 went ya-ha on Saturday. But they did bring pictures of primers.
Back to 'Ifs'...If our buddy stops the importation of spamcan surplus 7.62x54aarrr, then the popularity Mosin Nagants is dismal. That is just speculation.
