777 and Pyro scares me how fast it will rust up a bore. I have heard that you should hunt with a dirty bore, to get a better seal. My ML season lasts 2 weeks, and I always buck hunt only, as it is in the middle of the rut, so I may not fire my ML for the entire 2 weeks. If I hunted with a dirty bore, that would mean letting 777 fouling sit there for possibly up to two weeks, and I just dont want to do that with a 500$ gun. So I practice with a clean bore, I clean between every shot while practicing, to simulate a hunting shot. Am I strange for doing this? Am I missing something by doing that? Do most people hunting with a dirty bore and just buy a new gun or barrel every few years when it rusts out? Thanks for any info, this site is amazing, I am finding answers to questions I have had for a long time.
