So, after doing some math, Target Sports reference, 5K rds of Wolf - $1800; Tulammo $1498; Federal brass $3747. I'd buy the steel, shoot up the 5K rounds, take the $2K I saved and buy another rifle, still saving about $1300.
Part of the problem is stuff like Fed XM193 is considerably more powerful than most of the steel trash ammo. The steel junk most people
shoot isn't even in the same category.
The argument becomes more compelling if someone actually takes steel cased ammo and loads it to 5.56 specs. I think Hornady might have been the only
one that did this at one time.
The money you saved? Depends on how long it took you to use all that ammo. If you don't shoot a lot it could take you several years to
save the money and it's lost in the noise. I otherwise agree, in principle, if you're burning up a shitload of ammo on an annual
basis, the concerns about burning up barrels or whatever are pretty much moot, then again the whole thing becomes moot.... if you can afford to shoot up 5000 rounds of factory ammo of (whatever) every year then the cost of just getting another stick or whatever likely isn't a big deal anyways, or you already have a few different rifles to shoot.
