@dntworry I would just shoot the 42 load. I don't buy into the graphing method. Too many variables, esp if your load process is not 100% spot on with everything you do. I have gone to shooting until I see signs of pressure then backing off 2.5 grains and shooting in .2 grain increases for 1 grain. I just did 4 rifles, they all landed in that area. It is a lot faster method. Bryan Litz told me about it at Shot Show this year. I reviewed previous loads for multiple rifles, and they landed in that area too. I am running these at .025, it is where I do all my load development. If I have to do a seating test, I will start at .010 and go to .035 in .005 increments. I load a bunch at .010 and use a Lee hand seater at the range. I rarely have to adjust seating though. Your 42 group looks nice with a good ES/SD. I would run it. Shoot it at distance, get more chrono data as you go too, but that looks like the load.
