I'm not looking at it to go up much more than it already has. I wouldn't be buying any more for investment purchases. I think almost everyone who is going to buy a gun has already done so. However, I would keep at least a 1,000 minimum for every gun in the house. If you plan on practicing, you will need to replenish that stash. 2,000 rounds for each .22. You will notice that non-military calibers have become hard to find and/or very expensive.
The last 3030 rounds I bought maybe a year back was a dollar a round, same for 30 cal M1 carbine rounds. I bought a Ruger 9mm carbine just because the ammo was cheap, now can't even find it.
According to all the GOP money beggars they swear that if I don't send them some money today they will tax my weapons $800.00 a year plus, plus, plus.
