My opinion
White box = shot fine, cleaned up good, never had a hang up or mis-fire.
Tulamo = shot fine, never had a hang up or mis-fire BUT, I shot 100 rounds and it looked like I had fired 500+ rounds of white box when I got home to clean it. I had just enough to clean up "The normal amount" of carbon as I had experienced with white box and I had to go to the Gun Shop and get more cleaning supplies. I was pissed. Never going to shoot it again, I don't care how much money I could save.
The last couple boxes I have shot was a brand I believe was called American Eagle. It was 165gr instead of 180gr like the others. I shot better with it after a few boxes and it was only $15.99 per 50 round box. The owner of the gun shop said that he would let me place an order to stock up on ammo and the price would be about $12 per box if I did so. I am going to take him up on the offer.
The owner of the gun shop said that there is a reason why he doesn't carry Tulamo, because he can't sleep at night knowing he is destroying people's weapons. He has nothing to gain by telling me that they are junk so I took his word for it. He said I had gotten lucky that I had only shot 100 rounds of it cause he hears people complaining all the time about it.
