There's a difference in terms of salaries and costs in USA for sure (I know there is, especially for some jobs).
If I can save about 40$ for 1000 rounds, that's a lot. I try to pick whatever costs less and works, for training.
At the moment I'm paying about 3-3.5 cents (€) per bullet, 1.7 cents per primer, and about 1 cent per cartridge in terms of powder. That's about 6€ for 100 rounds. Factory rounds cost 10-14€ / 50, so from 20 to 28 for 100 rounds and it's nothing special, just FMJ bullets with a really hot load. That is using cast bullets (in training)
For competitions I'm using slightly better components, unless I find what works better.
Color coated bullets
Murom primers (2.5 cents per primer) -> they are soft like federal, just not as consistent
Same powder (at the moment)
Once fired brass, which costs me about 30€ / 1000. Hard to find enough to use them all in competitions so I have to buy them for important matches.
Up to 20 yards, accuracy is enough for training, maybe not the best available. I can still hit stuff at further distances but not with consistency
