According to most internet FB groups the 350L is the most accurate cartridge on earth. 10 shot groups under a 1/4"!!!!

Honestly though. It can be extremally accurate. More than it should be. But you will need to reload. Be careful of some of the factory loads. Right now it seems federal it blowing primer pockets like Win did at first. I have been picking up all kinds of them blown out at several ranges. All were FC headstamp.
