Thanks guys!

I see so much stuff on the topic, but rarely all in one place.
Now, I have a 30.06 and it looks like it wouldn't have enough space on the face of the muzzle to do anything fancy with it. Are these step crowns and things more commonly found on bull barrels or varmint barrels? I understand the gimmick of the recessed crowns or counter-boring. They say that in setting your crown back into the barrel a little ways, it protects the crown and rifling from damage if you were to knock your rifle on something.

Another thing I've wondered, is aside from the crown being even, and perpendicular to the bore, is there really any more effect to having a specific style of crown? Or, do different crowns produce different effects? The gas escaping evenly from all sides of the bullet the moment it leaves the barrel is the desired effect of any crown, but do any of the different styles do anything more than that?

Thanks for all your help by the way. It's just something I've been curious about.
