If you wanna use .5 grain increments you can, but once you get close to max such as you are now with 65 grains, then .2 increments of increase are better imo.
Increasing by increments of .2 of a grain narrows down more precisely or pinpoints better the max charge your rifle accepts.
Once you get to that point, back off 1/2 grain.
