csk and chamfer

I always run new rifle or handgun
brass thru a chamfer-ing and csk-ing
procedure to remove burrs before reloading.
I don't seem to see new ammo being chamfered.
Is this the norm, have I been wasting my time
for yrs?

Thanks-Ron

  I certainly don't consider neck sizing,trimming, and chamfering new brass to be a "waste of time". I made the mistake of NOT following this procedure on some 220 Swift brass a while back in an effort to produce some shooting ammo for a rifle test. The result was disappointing accuracy and a couple of instances of the bullet being pushed back into the case(bad news any way you look at it). Ended up pulling those loads and properly processing the brass anyway.

  rong,
  
  I guess I'm a creature of habits which always seem to promote a better end product. It is never a waste of time or effort to process brass, handgun or rifle, when starting with a new batch. Most factory brass has flaws in one or several places from a lack of attention to the process by the factories. Their goal is to produce a case as cheaply as possible then let us finish doing their job. Packaging will contribute to some of the flaws so final processing by the reloader is a necessity. I have found flaws in some of the most expensive and highly vaunted Lapua brass which required corrections.
  
  I always clean and chamfer the flash hole, size and cut the primer pocket, re-size, then trim and chamfer the case mouth. If I'm working on competition brass, it gets weight sorted.
  
  Best.
