I've used MagTech by the case in 38, 40, 44 mag, 45, 357 and 30 carbine. Good stuff at good prices. Price was what drew me to it to begin with, good results keeps it at or near the top of my shopping list.
MagTech "Guardian Gold" is a new line of hollow point ammo aimed at LE and home defense. The prices MAY sound cheap until you notice it's 20 round boxes.
