I am just starting into gathering the components to reload for the 444 Marlin round. The bullets I have vary somewhat in diameter and I was wondering if that would be cause to adjust powder loads. I have some 300 gr JFN that measure .430 and some 265 gr. JFN that mic out at .429 (just like the Hornady box states) Should this .001 be something I should worry about? Rather ask the question that have to ask the smith to fix something down the road. Thanks
