I have not tried the ammo. All I shoot in my 358s is that bullet though. It is very accurate and is a great deer bullet. It has taken a long time but it looks like the 358 is starting to get the respect it deserves. There is also a several different premium loads being offered by double tap. Expensive but at least you don't have to be a handloader to get the most out of this fine cartridge anymore.
