that depends on how well regulated the barrels are. some of these guns regulate well some don't. if you have one that regulates poorly then you could use one sight for each barrel. some of these rifles regulate better with RB's and some with bullets. my .50 and .58 Kodiaks wouldn't regulate with RB's although the individual barrel groups were tight. so i could have used the one sight for each barrel idea. i personally prefer a load that makes both barrels hit to the same spot or close to the same spot. in my rifles it took a conical to do that. my .72 Kodiak shot RB's from both barrels within an inch of each other at 50 yards with the first load i tried. my .50 was the most difficult and time consuming to get a load to bring the barrels close together. if fact it was the worst one with regulation as when i finally got it to quit cross firing by upping the bullet weight one barrel still hit higher than the other. at 30 yards it was negligible but at 75 yards it was more like 4-5" and at 100 yards it was 6-8".Supercracker said:
