Careful with that strategy, it will cost you thousands in the end. One day soon you will look at that stack of ammo and say hmmm I Need to get a new gun in .40 S&W and a 10mm and a ....And yet Remington is bankrupt. If you go bankrupt during one the greatest gun and ammo buying panic I’ve ever seen, then you are a shit company.
On a side note I’ve started buying a box or two of ammo for calibers I don’t have guns for. Even though I don’t have 10mm or 40s&w etc someone I know may and then I can trade then for stuff I do shoot if need be
After the 17 HMR was rolled out in the early 2000s I went and bought one and ordered 2000 rounds with it. I was assured I would have the ammo when the rifle was ready to pick up. Well, I got the Rifle one week later but the ammo didn’t show for 6 months. Now I buy 1000-1500 rounds of the new caliber I am interested in before I buy the gun.
