With Steel Challenge, you just have to hit the target, doesn't matter where. Unlike Bulls eye, competitions. So I load the cheapest lead coated bullets I can find. I will even shoot just plain lead bullets also, if the price is right, barrel leading to date has been minimal. So I don't worry about it. Plus accuracy with coated or just plain lead bullets has been quite good. To me speed shoot ammo, does not need to be as precise. so cheap bullets work just fine. I get mine from BlueBullet.com and Missouri bullets. I'm a tight wad, so I like cheap.
