What I normally do is run 1/2 gr increments start to max if it's something that 80gr powder I may use 1gr increments between start and max. If I use more than one powder I'll clean between powders and I normally take another rifle or two along that way I give the barrel time to cool off and gives me something to do.

here is two targets one is from my 243AI and the other one is from new 300Wby I was working loads up. I had two 4 shot loads groups pretty close just over 1/2" next load 1gr more first shot to the right too far out not worth trying again.

I hate to posting pictures but I'll invite Clark to come out and shoot with me and I'll load him one of those rifles he doesn't think too highly of.
