[QUOTE="yorke-1, post: 1445539, member: 11960"] I've done it both ways, where I have a separate scope for each barrel and where I make adjustments to the zero for each barrel. If the barrels are in similar chamberings it worked well to just make adjustments to the scope. The adjustments were typically pretty minor. This method worked best for me on a 3 barrel gun built by Jim Borden with 270 RUM, 7mm RUM and 338 Edge barrels. The adjustment from one barrel to the next was less than 1 MIL and it was consistent every time. On something with a more dramatic change in caliber it worked better to have separate scopes. I had a Savage which I'd change between 22-250, 260 Rem and 358 Win barrels. That one used two different scopes because the POI shift was more than 6 MOA between the 22-250 and 260 and a 20x scope was pointless on a 358 Win. It was the same when going from a 6.5-06 to a 338 Win Mag on the long action Savage. [/QUOTE]
