My personal opinion - late 2014 was the time to buy. There was massive oversupply and dealers were facing the new reality of the market glut - so amazing deals were to be had. We are still in the tail end of that, but prices basically only have one direction to go right now (with the exception of .22 LR and M855). Copper prices are also at record lows, with people closing copper mines in fact. Prices are still close to bottom right now.
This is going to change. The market always self corrects, and those who can't survive on razor thin margins or even losses (after all operating expenses are added up), are going to start falling off. Prices are going to start creeping up, and already have. We are still in the good times; if you think a $100 price increase is bad, wait 6 more months - because in my opinion you're never going to see prices this low again on pretty much anything ar15.com related.
Spend the next 3 months stocking up on guns, magazines, and non-223 based ammunition gents - is my advise. After that's done, budget funds to start resuming .223 stockpiling, after this current M855 silliness is over. My go-point for brass 5.56 ammo right now is $300/1000. If you see new brass 5.56 for that, get it.
As to reloading components, gunpowder is still rare and overpriced, but primers are cheap again - if you know where to shop. Look at the S&B primers, which are going for about $20/1k right now. That's a great deal. Wolf primers used to be a good deal, but I can't say if their QC today is as good as it once was. There are some great deals on bullets out there too. Sit tight on the gunpowder, it'll probably still come down over the next 6 months.
That's my budget planning at least.
