I like to try all sorts of different brands, bullet types and grain weight. Usually continue to buy whatever is inexpensive and has proven reliable once I've done the aforementioned. Fiocchi, S&B, Geco, American Eagle, Winchester, Remington, Blazer, PPU, PMC, Magtech all work. Magtech is probably my least favorite, made the list in order of favorites. When it comes to testing HP's I like the 185 or 200 grain options. Speer Gold Dot, Federal HST, Remington Golden Saber, Hornady Critical Duty 220+p. I have noticed with practice ammo, the Blazer doesn't seem to be as consistent (accuracy wise) as Fiocchi, S&B, our GECO, and Blazer isn't always cheaper then those brands in FMJ. Magtech seems to be the dirtiest from my experience and they are no longer inexpensive like they seemed to be years ago. My experience with these brands, seems similar regardless of the firearm or caliber I am shooting.
