I have also seen persons pay large sums of money for instruction that I would not trust to use a Daisy Red Ryder without shooting their own eye out, even after attending several classes...This is not aimed to start a fight, but to follow this logic:
Think about how much you'd save if you just stayed at home and trained by playing Call of Duty?
It's also like saying that a Sniper is lesser trained than a Machine Gunner because he shoots less bullets.
I've seen way too many people just sling their reloads downrange and call it training. The quality of training will make up for the quantity of ammo. I realize money is tight, but invest in training, you'll gain dividends in your skill faster than the investment in reloads.
