James Jones said exactly what I'd tell you. I have about 15 different boxes of factory ammo for 30-06. Different brands, bullets, weights, you get the idea.
I did that because I keep sighting in everyone elses 30-06 and finding their best factory load because they aren't handloaders.
Currently I have an encore with a 26" 30-06 barrel and it doesn't shoot the 168gr federal match ammo worth a darn. I have a Savage on order in 30-06 so I'll see what it can do. I have high expectations for any savage.
