For lead Titegroup runs a little hot, and HS-6 is great once up in pressure but generally works better with heavier projectiles. I've had great results using Titegroup with both Copper coated and HiTec coated bullets, a little goes a long ways so be careful of double charges but the nice aspect besides economy is how even though the charges are small they aren't position sensitive. I use a fair amount of HS-6 in 9mm but only with 124-125 gr bullets and near max charges.
