I would say that a lot of folks who intend to shoot a lot of that ammo are making bad decisions. You shoot the cheap stuff in practice, the expensive stuff you save for a specific purpose, like, hunting.
I would definitely shoot $2 a round ammo - as sighting in, and then carrying some for field use would amount to less than 50 rounds a year. Therefore, a .375 Socom is in my short list. Especially if the ATF Form 4999 becomes a reality and AR pistols are thrown into some twilight zone for years as we oppose it in the courts. I would then have major components rather than finance another lower and upper, which isn't really so much.
The point is that when AR15 alternative cartridges started coming out, with the 6.8 leading the advance, some of the first complaints made were that the ammo was Pricey! It was as if some expected a commercial round (however originally funded) would somehow sell for the same price as surplus. And then the next on the popularity surge suffered that, 6.5 is too Pricey! Then, .300 Blackout is too Pricey!
Nobody promised us a rose garden, the only way you get around it is reloading or buying a mass produced government supported cartridge with volume discounts. The exception is .50 BMG, and by golly, that stuff is still too Pricey!
Now that reality has intruded on some of the newer firearms owners, the practice of shooting 500 rounds in a range day is sinking in. It was always a special niche using surplus battle packs as low as 13c a round manufactured before the shooter was even born. As the worlds armies converted from one cartridge to another, and as those early stocks of the newer cartridges aged, we got cheap ammo. Now those governments don't wholesale it off any more, to prevent stocks from getting into the people's hands and fueling opposition to their overreach. No, cheap ammo isn't common anymore.
Lets not forget that this has been going on for a long time. Do you know why the CMP is selling a few 1911's at a time now, on lottery? Because Clinton had millions scrapped - literally thrown into large machinery resembling oversized ice crushers - and destroyed. Governments ruled by the likes of him have not only destroyed weapons but also block ammo sales as much as possible. SIG had to separate American operations to avoid German government interference. The golden years are long over.. And we aren't going back.
So, double the price on the OP's survey and you get an idea of what we face, sooner than we think. It's their agenda, not supply and demand, to make ammo so expensive we simply can't and won't shoot as much.They are even going to far as to illegally propose taxes and seize firearms if you are not compliant.
You do not comply your way out of tyranny.
