Throwing this out there, an old boy told me a long time ago not to spend too much money on barrels and triggers to improve accuracy when a 15 dollar flash hole uniformer would tighten up a group better than anything .
Actually,  probably $3.00 would get you one when we had the conversation.

Maybe before we begin to even attempt to discuss accuracy, we should define what accuracy actually is, or at least what it entails.
Accuracy is the ability to correctly strike the target that is intended to be struck.
Note that this is quite a bit different from shooting a series, and measuring how close or far apart the holes are.
Shooting groups does give a good indication of gun + ammo consistency, but it really doesn't measure functional accuracy.
Some consistent combinations will be accurate, but others most definitely will not be. So, in a sense then accuracy is situational. If you are in the field intent on making a shot, small groups may improve one's confidence, yet functionally offer nothing over a combination that shoots larger groups. I've actually seen this many times.
Functional, or field accuracy as I like to call it, is arrived at via a long list of factors, including some we would consider intangibles. 
Group shooting is about 180` apart, since it seeks to remove and isolate the shooting experience from the person.
Any who, not sure if field accuracy is a useful concept in today's high tech world, but it's a definition that has allowed me to enjoy arms that don't shoot several rounds to a tiny hole.

Have to agree, I have found out the hard way that it's tough to find a bench and a sandbag when the elk are milling around and starting to look nervous out about 350 yards...
