I can get a metal 75 round back loader for $70, or a Russian top loading snail mag for $250. I want to get at least two. I have heard from multiple people that the snail drum is better, but is is that much better? I'd like to have this tucked away before the fall, and I don't mind buy once cry once but I'd like to hear from someone with experience using both if they think it's worth the extra dough.
