It's hard to do this. It's not unlike choosing the fastest checkout line at the grocery store. Ammo? Reloading components? Lower receivers? Magazines? Where do you focus your limited funds? It's like investing in a 401k-how do I spread out my investments so as to minimize risk and maximize profit?
I've found that, by spreading out what I spend my money on-a few magazines here, some components there, factory ammo here (I almost never buy actual guns anymore-too expensive), that what I actually end up with is an underprepared state in every category.
I've already eliminated all of my competitive shooting, all practice shooting, all professional training, and I've dropped my gun club membership, and still there isn't enough money to fully fund the purchases at the center of this discussion.
Life happens I guess. While reading the comments here motivate me to prepare more for the future, the lean times have already struck. It looks like I'm about as prepared for 2020 as I'm going to be.
