Your post makes me cringe more and more every time I read it Loner, I can' t find anything to agree with in the length of it! You' re getting away with it because it' s only hunting, where exacting inches aren' t always important with a .30-06, put some holes in paper sometime and you' ll see the fallacy with published data sheets/programs. The remington and similar software are great starting points, to give you an idea, but should NOT be taken to the field as gospel. 30yrs of poor practices doesn' t make it a good idea, people have been cutting holes in their skulls for thousands of years to vent bad spirits, longevity doesn' t mean it' s a proven method. I' m sure you' ve done well as a hunter, but a dedicated trip to the range would show you a lot of things you might not be expecting. Those charts are good enough to get you ' more or less' sighted in, just enough to guarantee you' ll be on the page, with a .30-06, you' re flat shooting and straight flying enough that I' m sure it' s close, but measuring variant MOA at 30yrds is a joke, at 200yrds it' s quite noticeable. I don' t mean to tell a man his business, but I wouldn' t shoot/hunt with you if I knew that' s all the ' practicing' you did.
