I'm just getting into prs shooting. I'm a little ocd with wanting things to be pretty accurate. My current charge master can be +-.1 grains and I don't love it. I don't even feel like I can do ladder or OCW tests accurately because my charge could be off. If I have the money and want the peace of mind that my charges are pretty close. Is it worth it over the chargemaster? Have any of you switched from a charge master?
