Here is what we shot off in one AFTERNOON:
3,000 rounds .223 Rem
2,300 rounds 7.62x39
2,000 rounds 9x19
1,400 rounds .45ACP
1,000 rounds .40S&W
1,000 rounds .22LR (2 boxes of 500 ea)
500 rounds 12-ga (assorted, birdshot and sabot slug)
150 rounds .44 Magnum
12 of the 1/2 pound Tannerite exploding targets
And there were only 5 guys shooting! All but the .22LR and the 12-ga ammo was reloaded ammo. My buddies pay me for materials + labor, I reload, we go out and (literally) have a BLAST!
If you shoot a lot of pistol/rifle ammo, and you have time on your hands (like weekends and such), and have the mindset for strict attention to detail, then you may want to look into reloading. Besides, when SHTF, what'll you do when you're out of ammo and the zombies will come back at sunset?
It is actually a very simple process. The only "difficulty" is the need to pay close attention to detail. Remember: if a loaded round gets screwed up, it could blow your gun up! I find it easy. It is demanding in detail and attention, but only insofar as the setup of each step is concerned. After that, it is brainless work.
I go with all mags loaded plus 100. I found out I can only take what I plan on shooting otherwise they would all be be gone at once! Practice is usually Purposeful, working on very specific aspects of shooting. Grip positioning and control, recovery for double tap. We also concentrate on tight groupings which is where I suffer the most although greatly improved.
When you are practicing drawing from concealed holster, do a lot of dry-fire practice in front of the mirror, with no ammunition in the room with you!! Then go to the range, in front of a target draw and fire one round. Repeat as necessary to be able to bring your point of impact into CBM. This requires a LOT of practice, and a LOT of ammo! Have fun!
