I have a small box of rejects to be pulled. Pretty much setup pistol rounds that failed the case gauge. All pretty much due to the full lenth size die not being screwed in far enough. They've never made it to the range, and I can either save the components or scrap them
There are a few that showed signs of pressue, that are also in the rejects box.
I've loaded test load batches that didn't meet my accuracy requirements, and they go in the plinking pile.
I'd take the VAST majority of my handloads over factory ammo. I'd take my .308 Win over Fed Gold Medal Match or Black Hills in a heartbeat, (both primo factory), since it's tuned to my .308 and shoots better. I'd take my 6BR Norma over Lapua loaded rounds as well, for the same reason.
Folks seem to get into reloading, hoping to save money. For most, it never happens. You just shoot more, and build better ammo with better components than you would find in factory ammunition.
I have several rifles that have never seen factory ammo, and I hope they never will. They're happy guns that are well fed, and my buddies at the range believe they are better guns than they are, since they shoot well due to having ammo tailored to them.
Your AR can have significant variety in it's diet. You'll soon feel sorry for those lost souls on AR15.com just hoping to scrounge any 55 or 62 Gr FMJ on sale, cheering for Wolf. You end up shooting 69 Gr MatchKings for the same price, with 60 Gr V-Max for some spice.
What is also great about reloading, is having purpose built ammo optimized for your rifle. I've got favorite loads in pistol rounds for IPSC, steel targets, personal defense, and bullseye. I've got favorite loads for my benchrest gun that serve for targets, and another for varmints. I've got .270 loads tuned for big game with 160 Nosler partitions, deer with 130 gr bullets, targets with 135 Gr MatchKings, and wickedly accurate varmint loads with 110 V-Max and 90 Sierra BTHP Varminter rounds. Then there is that fact that I can feed my 6.5-06...where are you gonna get that at a store, and what would it cost you?
Once you reload, you'll hate the idea of factory ammo. They can just discontinue your favorite round, or change it and it will no longer shoot well in your rifle.
Reloading will forever raise your expectation of what good ammo should be. It's the gun equivalent to sex, after you start, the world is different
