Ok, I don't own a "real" double but am going to put a scope on the EAA O/U .30-06 I just bought. Do you zero the scope to your most consistant barrel or as a rule should you zero it in the center of the two barrels at what ever range you are zeroing at? I have only fired 20 rounds from this rifle at 25 yards (barrels keeping the shots within 2 inchs offhand for 4 shot groups) so I may be hasty but I have a spare 2-7 Burris Compact on hand. I won't be scoping my other double, a Pedersoli Kodiak in 45-70.
