The ammo issue for 300RCM I understand but the solution is pretty simple. Buy the rifle, purchase 5 boxes of ammo , purchase several bags of new brass. Most people aren’t shooting a 300RCM a ton.
But yes I understand and appreciate being able to walk into Walmart to buy ammo.
A gas station by my house has a case of hornady 300rcm
I got made fun of and heckled on here recently about gas stations selling ammo. When talking about it people acted like I had two heads.
