just a thought but sounds like a red herrin?????
i mean once you need the bdc seems like you'd be outa range??
heck i don't know just throwing something out there.
i may be missing something here, and i surely don't know what
i'm talking about here but, lets say you're looking at a 175
yd shot OK what would that be a 4 inch hold over? wouldn't need
a bdc for that. what would be the range here for an ethical shot? 200? 250?
i've shot slug guns before and couldn't get any kinda grouping past 100 yds
and decided not to hunt with it. this was 20 years ago and i realize they've come a long way
since then...
You could just use a mildot scope and use those marks for preset distances you choose after a range session, just an idea.
