I have 2010 Ruger M77 30-06 that I'm thinking about having re-crowned. I was looking at the crown yesterday while cleaning it and it seems that crown is relatively flat. I'm wondering if having it re-crowned with a target crown would be a good idea or not. Obviously I would find a very qualified gunsmith to do the work.

I'm interested in hearing everyone's opinions.
 
Pictures would let us get an understanding of what you're talking about with the phrase relatively flat. There is a target crown that is only 11 degrees from "flat". There is a recessed target crown, which is flat except for the very smallest part around the bore.. which is 45 degrees.
 
What's your concern?
Hunting Rifle, Factory Ammo?
If you can put 3 shots into 2 and1/2 inches at 100 yds from rest with factory ammo, the rife is fine.
Average shooter, worried about your "deer rifle"?
Don't spend money needslessly.

It's grouping better than 2.5" at 100yds.

If by 'average shooter' you mean not on the range every weekend, then yes I am an average shooter and yes I am talking about the rifle I take to the deer woods when I go during rifle season.

My concern is that accidents do happen and I can handle it if I have to replace/re-sight in a scope, but I'd rather not have to correct damage to the crown if there are steps that could be taken to minimize the possibility of damage (does that make sense?).

Maybe I'm over thinking it, and if that's the case I'll happily admit it.
 
No.

A crown is a crown, regardless of what shape it is.
If it was cut square with the bore the first time, it will remain sqaure with the bore forever.

The only time a re-crown is called for is if it is damaged with a cleaning rod, or if the barrel is shortened for some reason.

Best test for damage I know of is a cotton Q-Tip.

Run it in & out of the muzzle and around and round it.

If there are any burs or defects, it will snag up some cotton fibers and you can easily see them.

Another good test is to look at the carbon fouling pattern on the muzzle.
If it is star shaped to match the rifling grooves, and even all around the muzzle, the crown is perfect.
